App. 1a-11a) is reported at 665 F.2d 48. The opinion of the district court (Pet. App. 12a-14a) is unreported. The decisions of the Social Security Administration Appeals Council (Pet. App. 16a-19a) and the Administrative Law Judge (Pet. App. 20a-29a) are unreported. JURISDICTION The judgment of the court of appeals (Pet. App. 32a-33a) was entered on November 30, 1981. A petition for rehearing was denied on February 11, 1982 (Pet. App. 30a-31a). The petition for a writ of certiorari was filed on April 26, 1982, and was granted on June 21, 1982 (J.A.56). The jurisdiction of this Court is invoked under 28 U.S.C. 1254 (1). STATUTE AND REGULATIONS INVOLVED The pertinent provisions of Sections 205(a) and 223(d) of the Social Security Act, 42 U.S.C. 405(a) and 42 U.S.C. (& Supp. IV) 423(d); 20 C.F.R. 404.1545; 20 C.F.R. 404.1560 to 404.1569; and 20 C.F.R. Part 404, Subpart P, App. 2, are set forth in Pet. App. 34a-75a. QUESTIONS PRESENTED Whether the Secretary of Health and Human Services in appropriate cases may rely upon published medical-vocational guidelines, rather than testimony of vocational experts, to determine the existence of substantial gainful work in the national economy for disability claimants under the Social Security Act. STATEMENT 1. Titles II and XVI of the Social Security Act provide disability benefits to individuals who, because of a physical or mental impairment, are unable to do their previous work or to "engage in any * * * kind of substantial gainful work which exists in the national economy * * * ." 42 U.S.C. 423(d)(2)(A), 1382c(a)(3)(B). /1/ In determining whether a claimant is disabled, the Act requires the Secretary of Health and Human Services to consider, in addition to a claimant's physical and mental impairments, the vocational factors of age, education, and work experience. Ibid. In 1978, after years of study and consultation with Congress, and after giving interested parties notice and an opportunity for comment, /2/ the Secretary promulgated regulations governing the effect such factors should have in disability cases. 43 Fed. Reg. 55349 (1978). The regulations became effective on February 26, 1979. Ibid. /3/ The regulations are the basis for hundreds of thousands of disability determinations each year. The disability hearing system managed by the Department of Health and Human Services pursuant to the Social Security Act is "'probably the largest adjudicative agency in the western world.'" Santise v. Schweiker, 676 F.2d 925, 930 (3d Cir. 1982), petition for cert. pending, No. 82-5276 (filed Oct. 18, 1982), quoting J. Mashaw, C. Goetz, F. Goodman, W. Schwartz, P. Verkuil & M. Carrow, Social Security Hearings and Appeals: A Study of the Social Security Administration Hearing System xi (1978) ("Mashaw"). Approximately 2.3 million claims for Title II disability insurance benefits and Title XVI disability benefits were filed in fiscal year 1981. /4/ Department of Health and Human Services, Social Security Annual Report to the Congress for Fiscal Year 1981, 22, 26 (1982). More than a quarter of a million claimants requested hearings before an administrative law judge ("ALJ"). Id. at 29. More than 8000 filed suit in federal district court seeking review of an adverse administrative decision. Id. at 31. With respect to a large number of those claims, the ultimate question was whether the claimant's age, education, and work experience, coupled with his impairment, rendered him unable to perform "substantial gainful work which exists in the national economy." 42 U.S.C. 423(d)(2)(A). From an early date ALJs were required in many cases to decide that ultimate question with the assistance of vocational experts. See, e.g., Kerner v. Flemming, 283 F.2d 916 (2d Cir. 1960). These experts, who worked under contract with the Social Security Administration ("SSA"), were professors of rehabilitation counseling, directors of employment agencies, and other persons skilled in job placement and knowledgeable about labor market conditions. After evidence had been introduced about the claimant's medical problems and work experience, the vocational expert would be the last witness called by the ALJ. He would be asked to assume certain relevant facts about the claimant and would then testify about specific job opportunities for a person of that age, education, work experience, and medical condition. The use of vocational experts was fraught with difficulties. Not only did reliance on vocational experts produce inconsistent results in similar cases, but their testimony was time-consuming and expensive. The medical-vocational regulations /5/ were designed to eliminate the need for experts in a large number of cases. They establish a sequence for decision of disability claims. Before the guidelines in 20 C.F.R. Part 404, Subpart P, App. 2 may be consulted, the claimant must demonstrate that he is not currently working. If he is, the claim will be denied. 20 C.F.R. 404.1520(b). Second, the claimant must show, on the basis of medical evidence alone, that his impairment is "severe," i.e., that it "significantly limits (his) physical or mental ability to do basic work activities." If it does not, the claim will be denied. 20 C.F.R. 404.1520(c). Third, if the impairment is as severe as those listed in Appendix 1 of the regulations, 20 C.F.R. Part 404, Subpart P, the claimant will receive benefits without regard to his age, education, and skills. 20 C.F.R. 404.1520(d). Fourth, if the impairment is less severe than those listed in Appendix 1, the claimant must show that, because of his impairment, he can no longer perform work he has done in the past. If he can still do such work, his claim will be denied. 20 C.F.R. 404.1520(e). If he cannot do such work, there must be further factual determinations about each of the variables made relevant by the Act and the regulations: the claimant's "residual functional capacity" (i.e., the level of work he can perform, based upon medical evidence, despite his impairment), age, education, and work experience. 42 U.S.C. 423(d)(2)(A); 20 C.F.R. 404.1545, 404.1560 to 404.1568. With regard to each of these factors, the claimant may introduce evidence and rebut the factual findings made by the Secretary. 20 C.F.R. Part 404, Subpart P, App. 2, Section 200.00(a). It is only after this detailed and individualized factual inquiry into a claimant's medical and vocational characteristics that the guidelines and tables in Appendix 2 come into play. They are consulted to determine the one question that formerly was the subject of testimony by vocational experts: whether jobs exist in the national economy that can be performed by a person of the claimant's residual functional capacity, age, education, and work experience. The tables do not purport to answer that question for all claimants who have reached the last stage in the decisional sequence. For example, although many physical limitations are relevant to disability determinations, the tables consider only a claimant's strength. For one whose impairment results from mental or sensory limitations, a more individualized determination of available work must be made. 20 C.F.R. Part 404, Subpart P, App. 2, Section 200.00(e). For those cases in which use of the tables is appropriate, the Secretary in rulemaking proceedings has determined what jobs are available in the national economy. Underlying the table for sedentary work -- the most restricted category encompassed by the tables -- are approximately 200 unskilled occupations, each representing numerous jobs, that can be performed by claimants with the exertional capacity for a full range of sedentary work. 20 C.F.R. Part 404, Subpart P, App. 2, Section 201.00(a). See also Section 202.00(a) (1600 unskilled occupations for those able to do light work); Section 203.00(a) (2500 unskilled occupations for those able to do medium work). The weight given to the combinations of age, education, and work experience in each table is based on a further determination of the significance of those factors for the claimant's ability to adapt to new work situations. 43 Fed. Reg. 55353-55355 (1978). /6/ 2. Respondent filed a claim for disability benefits in October 1979, alleging disability due to a back problem and high blood pressure (Pet. App. 2a). Her claim was denied initially, and upon reconsideration (ibid.). On September 26, 1980, an ALJ concluded after a hearing that respondent was not disabled. He found that while she was unable to perform her past work, she retained the residual functional capacity for light work (id. at 22a-27a). The ALJ found that respondent was then 52 years old ("closely approaching advanced age"), had a marginal education, was able to read and communicate in English, and had unskilled work experience (id. at 27a-29a). On the basis of these findings, the ALJ applied Rule 202.10 in Table 2 of Appendix 2, which directed a conclusion that respondent was not disabled (see Pet. App. 69a). In December 1980, the Social Security Administration Appeals Council denied respondent's request for review (Pet. App. 16a-19a). /7/ Respondent then sought judicial review in the United States District Court for the Eastern District of New York. On April 29, 1981, the district court concluded that there was substantial evidence to support the Secretary's decision and dismissed the complaint (id. at 15a). The court of appeals remanded to the Secretary for further evidentiary proceedings (Pet. App. 1a-11a). The court agreed that there was substantial evidence in the administrative record to support the finding that respondent had the residual functional capacity to perform a wide range of light work (id. at 7a). It also did not dispute the appropriate classification of respondent's age, education, and work experience. The court of appeals nevertheless held that the Secretary, in determining whether there was "work * * * in the national economy" (see 42 U.S.C. 423(d)(2)(A)) that respondent could perform, was not entitled simply to rely on the tables in Appendix 2. Rather, the court held, the Secretary must "'identify specific alternative occupations available in the national economy that would be suitable for the claimant'" and give for each "'a job description clarifying the nature of the job, (and) demonstrating that the job does not require' exertion or skills not possessed by the claimant." (Pet. App. 9a, quoting Decker v. Harris, 647 F.2d 291, 298 (2d Cir. 1981)). Without such specificity, the court believed, "the claimant is deprived of any real chance to present evidence showing that she cannot in fact perform the types of jobs that are administratively noticed by the guidelines" (Pet. App. 10a). 3. The court of appeals did not specifically state that the medical-vocational regulations are invalid. The very purpose of the regulations, however, is to determine conclusively the types and numbers of occupations available, and their suitability for claimants whose medical and vocational characteristics are described in the tables. To reopen any of those questions is to render the regulations useless, if not invalid. Moreover, given the limitations on judicial review of agency action, see 42 U.S.C. (Supp. IV) 405(g), the court had no authority to supplant reliance on the tables in Appendix 2 unless the regulations directing such reliance are invalid. 20 C.F.R. 404.1569; App. 2, Section 200.00(a). /8/ The court of appeals also recognized that the demands it was making on the adjudicatory system had "(i)n the past * * * been (satisfied) largely through the use of vocational testimony to establish that there are specific jobs suitable to the claimant's capabilities" (Pet. App. 9a). It has since indicated its inclination to require the same procedure in future cases. Noel v. Schweiker, No. 81-6156 (2d Cir. Feb. 22, 1982) (unpublished). See Reply Br. 4. SUMMARY OF ARGUMENT I. The medical-vocational regulations implement the explicit authority given to the Secretary in 42 U.S.C. 405(a) and 42 U.S.C. (Supp. IV) 423(d)(5). Section 405(a) authorizes the promulgation of all rules "appropriate" to carry out the provisions of Title II and states that the Secretary "shall adopt" rules governing the quantity and quality of evidence necessary to support a finding of eligibility for benefits. Section 423(d)(5) reiterates the Secretary's power to regulate proof in disability cases. The regulations issued pursuant to this authorization to interpret the terms of the statute are entitled to legislative effect. Schweiker v. Gray Panthers, 453 U.S. 34, 44 (1981). The courts of appeals, with the exception of the Second Circuit, have given them that deference. The authorization for the regulations is evident not only on the face of the Act, but also in the legislative history that preceded and followed their promulgation. From the time the Act was amended to include disability provisions, Congress expressed a desire that the broad terms of the legislative definition be implemented by specific regulations based on the Secretary's experience in administering it. And for 18 years before promulgation of the medical-vocational regulations Congress expressed its hope that the Secretary would develop specific criteria to govern the effect of nonmedical factors on the evaluation of disability. Since the regulations were proposed, Congress has amended the disability provisions on six occasions, but has declined to disturb the regulations. II. The medical-vocational regulations are a significant improvement over the former procedure for evaluating vocational characteristics. The testimony of vocational experts about the effect of a claimant's age, education, work experience, and impairment on his job capabilities proved to be expensive, time-consuming, inaccurate, and inconsistent. Those difficulties resulted from a number of causes: the experts' knowledge of the labor market was both limited and variable; their testimony also slighted, on occasion, the vocational factors that Congress considered relevant; and perhaps most important, there was no way to assure that experts in different cases assigned the same weight to claimant's medical and vocational traits. The regulations replace that system with a uniform, accurate, and efficient means for making disability determinations, based on the job sources formerly considered by vocational experts, in the thousands of cases each year in which age, education, and work experience are relevant. III. The regulations are procedurally fair. They do not come into play except in cases reaching the last step in the sequential disability evaluation process. Even then, they are consulted only after all of the claimant's relevant individual characteristics have been ascertained through proof at a hearing. It is unnecessary to require, as respondent would (Br. in Opp. 9-10), that the Secretary identify specific jobs for a claimant in order to illustrate the meaning of residual functional capacity. The physical demands of jobs underlying the tables are clearly spelled out in the regulations, which are available to claimants at district and branch offices. Claimants have the right to be represented at hearings, and when they are not, the administrative law judge has a special obligation to develop a full and fair record -- an obligation that was satisfied in this case. It is also unwise to relitigate in each case, as the court of appeals would require, the question of the types and numbers of jobs that exist in the national economy. Even when vocational experts were used at hearings, proof of those facts was unnecessary in many cases. Moreover, the court of appeals erred in believing that it was necessary to prove the suitability of specific jobs for disability claimants. That burden need not be imposed because the guidelines only direct a finding of nondisability in cases where the number of jobs that exist is very large. Neither the court of appeals nor respondent has challenged the accuracy of the job data underlying the regulations and tables. Finally, the court's requirement ignores the Secretary's authority to dispense with costly fact-finding procedures in the face of a burgeoning disability caseload and to proceed by general rule. ARGUMENT THE MEDICAL-VOCATIONAL REGULATIONS ARE A LAWFUL EXERCISE OF THE SECRETARY'S RULEMAKING AUTHORITY UNDER THE SOCIAL SECURITY ACT I. The Medical-Vocational Regulations Implement The Authority Delegated To The Secretary By Congress Regulations that implement an explicit delegation of authority by Congress are entitled to legislative effect and should be upheld unless they are arbitrary or exceed the statutory mandate. The medical-vocational regulations are a reasonable and appropriate exercise of the Secretary's rule-making authority. They were adopted at the repeated urging of the congressional committees charged with oversight of the social security laws. A. The Regulations Carry Out Explicit Delegations of Statutory Authority In Connection With the Disability Programs 1. The medical-vocational regulations were promulgated by the Secretary pursuant to a broad grant of statutory authority. 42 U.S.C. 405(a) provides: The Secretary shall have full power and authority to make rules and regulations * * * which are necessary or appropriate to carry out (the) provisions (of Title II), and shall adopt reasonable and proper rules and regulations to regulate and provide for the nature and extent of the proofs and evidence and the method of taking and furnishing the same in order to establish the right to benefits hereunder. This section gives two directions. The first grants the Secretary "full power and authority" to promulgate any regulations "necessary or appropriate" to implement the disability provisions of the Act. The medical-vocational regulations are an appropriate means to carry out the statutory command that age, education, and work experience be considered along with claimants' mental or physical impairments in determining entitlement to disability benefits. 42 U.S.C. 423(d)(2)(A). The second direction in Section 405(a) is both more explicit and mandatory. It states that the Secretary "shall adopt" rules that are both procedural ("the method of taking and furnishing" proof) and substantive ("the nature and extent for the proofs and evidence"). In the second clause "Congress has authorized, if it has not required, the Secretary to issue regulations prescribing both the quality ('nature') and quantity ('extent') of evidence necessary to support a finding of entitlement to disability benefits." McCoy v. Schweiker, 683 F.2d 1138, 1143 (8th Cir. 1982). As the Eighth Circuit stated in McCoy (ibid.), "a decision as to what kinds of cases are appropriate for the testimony of vocational experts is squarely within the rubric 'nature and extent of the proofs and evidence.'" Section 405(a) is not the only basis for the authority exercised by the Secretary. 42 U.S.C. (Supp. IV) 423(d)(5) states: An individual shall not be considered to be under a disability unless he furnishes such medical and other evidence of the existence thereof as the Secretary may require. This provision repeats -- in the very section in which "disability" is defined -- the direction given in Section 405(a) regarding Title II generally: that the existence of a disability is to be determined according to standards regarding "medical and other evidence" fixed by the Secretary. /9/ The issue whether a vocational expert should be required to give evidence about the interplay of the medical and vocational factors with the demands of the labor market falls squarely within the authority given the Secretary. Other provisions in the same section underscore Congress's evident purpose to have the Secretary flesh out the meaning of the statutory term. The definition of disability, which merely directs "consider(ation)" of how the claimant's age, education, and work experience affect his ability to do substantial gainful work, 42 U.S.C. 423(d)(2)(A), is clearly not self-executing. It would be irrational to conclude that the Secretary has exceeded the generous scope of his rule-making authority by attempting to assure that a general congressional definition of entitlement is made specific enough to be applied consistently in vast numbers of cases. Moreover, the subsection immediately following the definition of disability states that widows and certain other claimants shall be considered disabled only if their "impairments are of a level of severity which under regulations prescribed by the Secretary (are) deemed to be sufficient to preclude * * * gainful activity." 42 U.S.C. 423(d)(2)(B). And 42 U.S.C. (Supp. IV) 423(d)(4) states that "(t)he Secretary shall by regulations prescribe the criteria for determining when services performed or earnings derived from services demonstrate an individual's ability to engage in substantial gainful activity." /10/ It would be odd if the Secretary were given the power to define by regulation the requisite severity of an impairment, but denied the power to specify what consideration should be given to the equally general vocational factors enumerated in the same section. It would also be strange if the Secretary were permitted to promulgate rules disqualifying claimants because of the kind of work they are currently performing, but not allowed to promulgate rules governing the effect that past work should be given. 2. This Court recently rejected a claim, similar to the court of appeals' conclusion, that the Secretary was required to make individualized factual determinations regarding the income "available" to Medicaid applicants under 42 U.S.C. 1396a(a)(17). That section states that the availability of income and resources shall be determined "in accordance with standards prescribed by the Secretary * * * ." In Schweiker v. Gray Panthers, 453 U.S. 34, 44 (1981), the Court held: In view of this explicit delegation of substantive authority, the Secretary's definition of the term "available" is "entitled to more than mere deference or weight" * * * . Rather, the Secretary's definition is entitled to "legislative effect" because, "(i)n a situation of this kind, Congress entrusts to the Secretary, rather than to the courts, the primary responsibility for interpreting the statutory term." * * * Although we do not abdicate review in these circumstances, our task is the limited one of ensuring that the Secretary did not "excee(d) his statutory authority" and that the regulation is not arbitrary or capricious. See also Herweg v. Ray, No. 80-60 (Feb. 23, 1982), slip op. 9; Batterton v. Francis, 432 U.S. 416, 425-426 (1977). With the exception of the Second Circuit, the courts of appeals have found "(t)he language of 42 U.S.C. Section 405(a) (and 423(d)(5)) * * * different from that of the authorizing statutes in Herweg, Gray Panthers, and Batterton, but * * * hardly less emphatic" (McCoy v. Schweiker, supra, 683 F.2d at 1144. They also have concluded that the medical-vocational regulations are an appropriate means of carrying out the Secretary's statutory authority. Id. at 15-22; 1144-1149; Torres v. Secretary of Health and Human Services, 677 F.2d 167, 169 (1st Cir. 1982); Santise v. Schweiker, 676 F.2d 925, 932-936 (3d Cir. 1982), petition for cert. pending, No. 82-5276 (filed Oct. 18, 1982); Rivers v. Schweiker, No. 81-1413 (5th Cir. Sept. 7, 1982), slip op. 4481; Kirk v. Secretary of Health and Human Services, 667 F.2d 524, 530-531 (6th Cir. 1981), petition for cert. pending, No. 81-6754 (filed May 20, 1982); Cummins v. Schweiker, 670 F.2d 81, 83 (7th Cir. 1982); Broz v. Schweiker, 677 F.2d 1351, 1357-1359 (11th Cir. 1982). /11/ See also Frady v. Harris, 646 F.2d 143, 144-145 (4th Cir. 1981). 3. It is not surprising that the courts have found, with such uniformity, that the medical-vocational regulations effectuate the Secretary's statutory authority. The definition of disability in the statute provides the framework both for the regulations themselves and for the guidelines and tables in Appendix 2. The statute declares that a claimant shall be considered disabled if his physical or mental impairment, taken together with his age, education, and work experience, renders him unable to engage in "work which exists in significant numbers either in the region where such individual lives or in several regions of the country." 42 U.S.C. 423(d)(2)(A). As we explain in Part II, the decision of that issue depends on several judgments that can most consistently, accurately, and efficiently be made by rule, rather than case-by-case adjudication. In the first place, the decision demands an encyclopedic knowledge of the types of jobs available throughout the country, the numbers of such jobs that exist, and the physical, educational, and experiential requirements for satisfactory performance of each type of job. The tables in Appendix 2, which are the product of years of exhaustive research and public comment (see pages 2-3, supra), incorporate the Secretary's determination of how many types of unskilled jobs are available in significant numbers for people whose strength is limited in certain ways. See 20 C.F.R. Part 404, Subpart P, App. 2, Sections 201.00(a), 202.00(a), 203.00(a). /12/ The tables also incorporate the Secretary's determination that where a claimant has a greater level of education or work skills, he may have a greater range of occupations to choose from if his knowledge is "readily transferable to a significant range of semi-skilled or skilled work within an individual's residual functional capacity * * * ." App. 2, Section 202.00(e). They accordingly give separate consideration to claimants whose education or experience provides for direct entry into skilled work, based on the Secretary's determination of the availability of skilled and semi-skilled occupations. See 20 C.F.R. 404.1564, 404.1565, 404.1568. In the second place, the tables, guidelines, and regulations incorporate the Secretary's determination of issues that are less strictly empirical, but that Congress nonetheless left for his resolution. These include such factors as the effect of age on a claimant's ability to adapt to a new job and the number of job opportunities that will satisfy the "significant numbers" requirement in Section 423(d)(2)(A). A comparison with Appendix 1 will illustrate this point. 20 C.F.R. Part 404, Subpart P, App. 1 lists certain medical impairments thought to be so severe that they are per se disabling. Among them are deafness and muteness, App. 1, Sections 2.08, 2.09, even though many deaf and mute individuals in fact are able to hold jobs. On the other hand Appendix 1 does not list the loss of a hand as presumptively disabling, cf. App. 1, Section 1.09, even though that may be a great functional impairment. The line drawn is not a scientific one; rather, it represents an informed judgment about the individual's likely ability to adapt and perform successfully in a competitive labor market. See Goldhammer, The Effect of New Vocational Regulations on Social Security and Supplemental Security Income Disability Claims, 32 Ad. L. Rev. 501, 502-503 (1980). The same is true about the Secretary's determination of the effect of age, or his decision that a person who is 45, severely impaired, and illiterate is disabled, while an otherwise identical individual with a limited education is not. 20 C.F.R. Part 404, Subpart P, App. 2, Table No. 1, Rules 201.17, 201.18. Given the nature of those judgments, it makes little sense to repeat them, with varying outcomes, in individual proceedings. The very existence of a disability program necessitates the drawing of such lines, but the task of doing so was left by Congress to the Secretary. B. Congress Urged The Adoption Of, And Has Implicitly Ratified, The Regulations In 1954, when Congress amended the Social Security Act to afford disability coverage, /13/ it provided that an individual should be deemed disabled if he is unable "to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment" that could be expected to be prolonged or result in death. 42 U.S.C. 423(d)(1)(A). /14/ What Congress offered was "a legislative definition written in rather broad terms to be implemented by more specific administrative regulations on the basis of operational experience." Subcomm. on the Administration of the Social Security Laws, 86th Cong., 2d Sess., Administration of Social Security Disability Insurance Program: Preliminary Report to the House Comm. on Ways and Means 14 (Comm. Print 1960) ("Preliminary Report"); S. Rep. No. 1987, 83d Cong., 2d Sess. 21 (1954). Although the original statutory definition of disability was framed in terms of purely medical criteria, the Social Security Administration recognized from the outset "the importance of the nonmedical factors, such as age, experience, and education of the individual." Administration of Social Security Disability Insurance Program: Hearings Before the Subcomm. on the Administration of the Social Security Laws of the House Comm. on Ways and Means, 86th Cong., 1st Sess. 81, 82-88 (1959). Congress not only viewed that as an appropriate interpretation of the Act; it also suggested that SSA should provide by regulations the precise weight to be given such considerations. Preliminary Report, supra, at 18 (emphasis in original): The subcommittee recognizes the difficulty of developing and enunciating specific criteria for the weight to be given nonmedical factors in the evaluation of disability and the extreme sensitivity of this area. But the subcommittee believes that the time has come, if it is not well overdue, to make a determined effort to develop and refine these criteria and make them available to the evaluators and to the public in the form of published regulations. Although SSA developed administrative materials (for use by state agencies in their initial and reconsideration determinations) that detailed the weight to be given to vocational factors, 43 Fed. Reg. 55350-55351 (1978); see pages 28-29, infra, it did not issue vocational regulations at that time. In 1967 Congress amended the Act to make explicit its concern that such factors be weighed as part of disability determinations. 42 U.S.C. 423(d)(2)(A). It also redefined "substantial gainful work" to mean work that exists in the national economy, not work that a claimant could actually find in the area where he lives. Ibid. Although the legislative history of those amendments does not specifically address the publication of vocational regulations, it does make several points relevant to a decision about their validity. First, it notes with approval the approach that the Secretary had taken to implement the Act -- an approach that had included the use at the state level of materials very similar to the current regulations. See pages 28-29, infra; 113 Cong. Rec.23116 (1967) (remarks of Rep. Rostenkowski); id. at 23065 (remarks of Rep. King); see also H.R. Rep. No. 544, 90th Cong., 1st Sess. 28-31 (1967); S. Rep. No. 744, 90th Cong., 1st Sess. 46-49 (1967). Second, Congress noted its concern that the statutory definition "be applied with uniformity and consistency throughout the Nation * * * ." H.R. Rep. No. 544, supra, at 30; 113 Cong. Rec. 23065 (1967) (remarks of Rep. King). Finally, and perhaps most significantly, there is the stated recognition that the Secretary would continue to implement the statute through regulations that would explain and elaborate upon the broad statutory language. Concerning the newly adopted section on the effect of work and earnings, 42 U.S.C. 423(d)(4), the Statement of the Managers on the Part of the House declared (H.R. Conf. Rep. 1030, 90th Cong., 1st Sess. 51-52 (1967)): "The Secretary of Health, Education, and Welfare is directed to establish criteria which are to be conclusive for determining when work or earnings demonstrate ability to engage in substantial gainful activity." Similarly, both the House and Senate Reports state that the level of severity at which an impairment -- taken alone -- should be considered presumptively disabling is a matter for the Secretary to determine by administrative rules. H.R. Rep. No. 544, supra, at 30, 31; S. Rep. No. 744, supra, at 49. The administrative policies affirmed in the 1967 amendments continued, however, to be published only in the manuals used by state agencies processing initial and reconsideration determinations. They were not binding on or even readily available to administrative law judges or the federal courts. See 43 Fed. Reg. 55349 (1978). As a result, the first two levels of administrative consideration of disability claims applied standards not always reflected in the courts and in decisions of administrative law judges, who had to rely on the testimony of vocational experts. A 1974 report on the disability insurance program prepared by the staff of the House Ways and Means Committee criticized this situation. The original idea was that the broad language of the statutory definition would be amplfied by regulations based on operational experience. As it turned out the Courts, rather than the Social Security Administration or the Congress, have effectuated the major changes in the definition, particularly in the area of the definition's somewhat subjective nonmedical factors. * * * * * * * * * * * The staff believes that the Department of HEW with the assistance of skilled personnel from the State Agencies and those in the private sector with expertise in disability adjudication should explore the possibilities as to whether the definition of disability can be stated more specifically in the law or regulations, and whether more operational presumptions may be incorporated into its administration so that the definition can be more effectively applied to greatly accelerating caseloads. Staff of House Comm. on Ways and Means, 93d Cong., 2d Sess., Report on the Disability Insurance Program 6 (1974) ("1974 Report"); see also id. at 45, 50, 81. Several months after publication of the 1974 Report, the Social Security Administration completed an internal report on the disability claims process which also concluded that disability standards needed to be spelled out in regulations. Social Security Administration, Report of the Disability Claims Process Task Force 46 (1974), reprinted in Subcomm. on Social Security of the House Comm. on Ways and Means, 94th Cong., 1st Sess., Recent Studies Relevant to the Disability Hearings and Appeals Crisis, at 46 (Comm. Print 1975). The agency then drafted the medical-vocational regulations and began the review process that precedes issuance by the Secretary of a notice of proposed rulemaking. In the case of the medical-vocational regulations, this process involved extensive review by expert consultants, state agency personnel, and congressional committees and their staffs. In May and June 1976, the Subcommittee on Social Security of the House Ways and Means Committee held hearings that focused on the draft regulations. In connection with the hearings, the Subcommittee staff reprinted the regulations and prepared a legislative issue paper noting that Congress had been pressing for issuance of regulations on the vocational factors for 16 years. Disability Insurance Program: Hearings Before the Subcomm. on Social Security of the House Comm. on Ways and Means, 94th Cong., 2d Sess. 22, 166-266 (1976) ("Disability Insurance Program: 1976 Hearings"). In response to written questions from the Subcommittee, the Commissioner of Social Security stated that Section 205(a) of the Act, 42 U.S.C. 405(a), provided sufficient statutory authority for the Secretary's issuance of the draft regulations. Disability Insurance Program: 1976 Hearings, supra, at 289-290. In 1976 Representative Burke (Chairman of the House Subcommittee on Social Security) introduced a bill that would have required the Secretary to promulgate the medical-vocational regulations after a 60-day comment period. H.R. 15630, 94th Cong., 2d Sess. Section 7, at 23 (1976). Representative Burke acknowledged that it was too late in the legislative session to take action on the bill, but stated that he wished to focus discussion on the disability program so that action would be taken early in the next session. Subcomm. on Social Security of the House Comm. on Ways and Means, 94th Cong., 2d Sess., H.R. 15630 -- Disability Insurance Amendments of 1976, 1 (Comm. Print 1976). The next year Representative Burke introduced a revised bill. H.R. 8076, 95th Cong., 1st Sess. (1977). He noted that the agency had promised to publish a notice of proposed rulemaking concerning the medical-vocational regulations that year and that the Administration believed the regulations were authorized by the statute. Subcomm. on Social Security of the House Comm. on Ways and Means, 95th Cong., 1st Sess., H.R. 8076 -- Disability Insurance Amendments of 1977, 7 (Comm. Print 1977). Consequently, the revised bill included no provision requiring promulgation of the regulations. The notice of proposed rulemaking was not issued, however, by the time the House Subcommittee held hearings on the disability program in February 1978. In a colloquy during the hearings, the Acting Commissioner of Social Security stated that the notice would be published shortly. Disability Insurance Program -- 1978: Hearings Before the Subcomm. on Social Security of the House Comm. on Ways and Means, 95th Cong., 2d Sess. 66 (1978). A month later the notice was published, 43 Fed. Reg. 9284 (1978), a fact noted favorably by the House Subcommittee. Subcomm. on Social Security of the House Comm. on Ways and Means, 95th Cong., 2d Sess., Disability Insurance -- Possible Areas of Subcommittee Action 14 (Comm. Print 1978). Shortly thereafter, after considering several bills that would have redefined disability in the Act, the Subcommittee concluded that no legislative action should be taken until it could be determined whether operation of the new regulations adequately met the problems in the program. It unanimously approved a bill that included no change in the definition of disability. See Subcomm. on Social Security of the House Comm. on Ways and Means, 95th Cong., 2d Sess., Proposed Disability Insurance Amendments of 1978 (H.R. 14084) (Comm. Print 1978). The final regulations were promulgated in November 1978 and became effective on February 26, 1979. 43 Fed. Reg. 55349 (1978). Since 1976, when it first held hearings on the medical-vocational regulations, Congress has amended 42 U.S.C. 405 and 423 -- which define disability and authorize the Secretary to implement the definition with regulations -- on six different occasions. /15/ Among other changes, Congress has required the Secretary to justify unfavorable disability decisions with a discussion of the evidence and the basis for the decision (Pub. L. No. 96 265, Section 305(a), 94 Stat. 457 (Section 405(b)); amended the provision dealing with judicial review (Pub. L. No. 96-265, Section 307, 94 Stat. 458 (Section 405(g)); and enlarged Section 423(d)(5), which authorizes the Secretary to promulgate the regulations at issue here (Pub. L. 96-265, Section 309(a), 94 Stat. 459). On each of those occasions Congress declined to disturb the Secretary's exercise of his statutory authority of which it was fully cognizant. "Congress has been made aware of (the regulations), yet (six) times has 'revisited the Act and left the (regulations) untouched.'" Board of Governors of the Federal Reserve System v. First Lincolnwood Corp., 439 U.S. 234, 248 (1978) (footnote omitted), quoting Saxbe v Bustos, 419 U.S. 65, 74 (1974). In light of this history, the court of appeals was plainly unwarranted in rejecting the sufficiency of the medical-vocational guidelines to support determinations of nondisability. Judicial deference is especially appropriate "'when Congress has refused to alter the administrative construction * * * " and "that construction accords with well-established congressional goals." Board of Governors of the Federal Reserve System v. First Lincolnwood Corp., supra, 439 U.S. at 248 251, quoting Red Lion Broadcasting Co. v. FCC, 395 U.S. 367, 381 (1969). "(O)nce an agency's statutory construction has been 'fully brought to the attention of the public and the Congress,' and the latter has not sought to alter that interpretation although it has amended the statute in other respects, then presumably the legislative intent has been correctly discerned." United States v. Rutherford, 442 U.S. 544, 554 n.10 (1979), quoting Apex Hosiery Co. v. Leader, 310 U.S. 469, 489 (1940). See also Haig v. Agee, 453 U.S. 280, 300-301 (1981). II. The Medical-Vocational Regulations Provide A Uniform, Accurate, And Efficient Means For Making Disability Determinations The medical-vocational guidelines improve disability determinations made both by state agencies at the initial and reconsideration stages and by administrative law judges at the hearing stage. Before the medical-vocational regulations were promulgated in 1978, state agencies and administrative law judges integrated medical evidence with information about a claimant's age, education, and work experience in different ways. State agencies used detailed guides developed by the Social Security Administration that incorporated the same principles as the guidelines, but lacked the structure and organization of the tables in the guidelines. For example, the Disability Insurance State Manual ("Manual") provided in 1963 that "(c)ases should be put through sequential evaluation tests." Department of Health, Education, and Welfare, Social Security Administration, OASI Disability Insurance Letter No. III-3, at 1 (Sept. 20, 1963) ("DIL No. III-3). /16/ The first issue was whether the claimant -- if not actually working -- could be found disabled solely on the basis of the medical listings then found in 20 C.F.R. 404.1502(a) (1961). Except in unusual cases, see 20 C.F.R. 404.1502(c) (Cum. Supp. 1964), state agencies were then directed to determine whether a claimant was able to do his past work (DIL No. III-3, supra, at 3). If he was not, the next issue was whether there was other substantial gainful activity the claimant could perform. As an example, the Manual suggested (id. at 5): Generally, the applicant who retains the physical ability to do a wide range of light work, who is not of advanced age (ordinarily under 55 years of age), and is able to communicate, read and write on an elementary level may be considered to still be in the competitive labor market for light unskilled work, despite the absence of special experience or skills * * * . "Light work" was defined as: equivalent to lifting 20 pounds maximum with frequent lifting and/or carrying of objects weighing up to 10 pounds, or requiring walking or standing to a significant degree, or requiring sitting most of the time but entailing pushing and pulling of arm and/or leg controls. Bureau of Disability Insurance, Vocational Specialist Training Handbook 2-50 ("Training Handbook). /17/ Cf. 20 C.F.R. 404.1567(b). As is evident from the similarity to the currently effective provisions, these guides were incorporated into the medical-vocational regulations at issue here. 43 Fed. Reg. 55351 (1978). /18/ Although these state agency materials included the same principles as the current regulations, they "were often incomplete, vague, contradictory, time consuming to implement, and subject to divergent interpretations." Comptroller General of the United States, The Social Security Administration Should Provide More Management And Leadership In Determining Who Is Eligible For Disability Benefits 10 (1976). The 1976 study by the Comptroller General reported that a study of ten state agencies showed complete agreement on the proper disposition of only 22% of a test group of disability claims. Id. at 6-10. On the other hand, administrative law judges -- who were not bound by the Disability Insurance State Manual and to whom the Manual was not even generally available (see 43 Fed. Reg. 55351 (1978)) -- relied on vocational experts to weight the significance of claimants' medical and vocational characteristics. After evidence had been introduced about the claimant's medical problems and work experience, the vocational expert would be called by the ALJ. SSA's Office of Hearings and Appeals provided the following example of the proper method for an ALJ to question the vocational expert (1974 Report, supra, at 95): Q. Dr. Jones (the Vocational Expert), we have a picture of what Mr. Smith did in the past from the documentary evidence of record. Will you kindly summarize his background, especially his work experience and all other factors which you take into consideration in evaluating vocational capacity of an individual, especially Mr. Smith's. A. (Vocational expert summarizes claimant's education and work history.) Q. The jobs that you mentioned were jobs that you found the claimant had done some time in the past according to the record, is that right? A. Yes, sir. Q. Now, Dr. Jones, what is your understanding of sedentary work? A. (Answer given probably as in Dictionary of Occupational Titles.) Q. What is your understanding of light work? A. (Answer given probably as in Dictionary of Occupational Titles.) Q. What is your understanding of moderate work? A. (Answer given probably as in Dictionary of Occupational Titles.) Q. Under the assumption that I will find from the medical evidence in this case that there is no physical impediment to Mr. Smith's undertaking and performing sedentary (light or moderate) work activity, as same was described by you, do you know of any jobs which exist in this region which you feel Mr. Smith is vocationally qualified to perform based on his age, education, training, and background? A. (Vocational expert responds.) (T)he hearing examiner * * * can follow through for further amplification with specific questions as to the physical requirements, such as the necessity for bending, lifting, turning, stooping, etc.; the tools and equipment used; the working conditions * * * . In making his decision about the existence of suitable jobs for a particular claimant, the vocational expert would rely on the same sources that state agencies used in the initial and reconsideration decisions. /19/ Applying that information to particular cases required the vocational expert to make several judgments. /20/ These included: (i) in cases where the claimant had physical limitations other than strength (e.g., lack of dexterity, or a reaction to dust), the types of jobs unavailable because of the demands of the work or the environment; (ii) the effect of the claimant's education and skills on the types of jobs open to him; (iii) the effect of the claimant's age on his ability to adapt to his impairment and to a job situation requiring unfamiliar skills, and on his physical abilities (such as vision, hearing, manual dexterity, balance, and agility) other than strength; and (iv) given the types of jobs the claimant could perform, the number of such jobs existing in the national economy. Because of the nature of the judgments made by vocational experts, it is not surprising that they frequently reached inconsistent results in similar cases. Santise v. Schweiker, supra, 676 F.2d at 930. The apparent arbitrariness of this adjudicatory system resulted from a number of causes. First was the occasional failure of the expert to consider all the vocational factors that Congress considered relevant and to relate them to the claimant's medical condition. See Dobrowolsky v. Califano, 606 F.2d 403, 408 (3d Cir. 1979). Second, and perhaps more serious, was the tendency of experts to assign different weights to the claimant's relevant medical and vocational characteristics. Although the question about the jobs available to a claimant of a given description masqueraded as a factual issue, it actually involved judgments like those mentioned in the last paragraph, and policy decisions. For example, the statutory requirement that age be considered in determining a claimant's ability to perform a job (42 U.S.C. 423(d)(2)) is not susceptible of any precise calibration. There is unquestionably an "increasing physiological deterioration in the senses, joints, eye-hand coordination, reflexes, thinking processes, etc., which diminish(es) a severely impaired person's aptitude for new learning and adaptation to new jobs." 43 Fed. Reg. 55359 (1978); cf. Massachusetts Board of Retirement v. Murgia, 427 U.S. 307, 315 (1976). But precisely how those often unmeasurable effects of senescence should affect a claimant's entitlement to disability benefits is a matter that Congress did not specify and on which various experts could disagree. See also Mashaw, supra, at 78. Third, an important part of what the vocational expert did was to inform the ALJ of the number and types of jobs available in the national economy, and that question received different answers because of the ALJs' and the experts' "limited and variable knowledge of the labor market." Cummins v. Schweiker, supra, 670 F.2d at 83. There were other problems with the use of vocational experts as well. "Their usage in live testimony * * * increased from slightly under 5,000 in 1965 to over 13,000 in fiscal 1973." 1974 Report, supra, at 94. By 1978 vocational experts were used in more than 40% of all disability hearings, which by then numbered approximately 200,000 annually. DMIS/OHA, Participant Involvement In Request For Hearing Cases (Mar. 1982); DMIS/OHA, FY 81 Key Workload Indicators 1 (Nov. 20, 1981). That imposed significant monetary costs on the hearing process, since experts were under contract with SSA. 1974 Report, supra, at 94. It also was time-consuming. Kirk v. Secretary of Health and Human Services, supra, 667 F.2d at 530. The medical-vocational regulations were designed to resolve these difficulties. Most obviously, and most importantly, they address the problem of inconsistent treatment of disability claimants. One virtue of the approach required by the regulations is that it focuses the ALJ's attention on the specific factors that afffect an individual's employability. Before he can even profitably consult the guidelines the ALJ must take evidence and make specific findings regarding the claimant's residual functional capacity, work experience, education, and age. He must also consider any non-exertional physical or mental impairments the claimant may have, since the existence of such problems will preclude a straightforward use of the guidelines. 20 C.F.R. 404.1569; 20 C.F.R. Part 404, Subpart P, App. 2, Section 200.00(e). A second virtue of the regulations is that they provide a consistent judgment about the weight to be given the various vocational characteristics. For instance, the regulations eliminate the unfairness of treating claimants of the same age differently on the basis of unmeasurable facts about senescence. In place of the former system they provide, for example, that all those over 55 who are severely impaired, and have limited education and no work experience, are disabled regardless of their residual functional capacity. 20 C.F.R. Part 404, Subpart P, App. 2, Tables 1, 2 and 3, Rules 201.01, 202.01, 203.01. They also provide that all impaired claimants over 50 who are illiterate and unskilled are disabled, unless they have at least the residual functional capacity to do medium work. See, Rules 201.09, 202.09, 203.18. Each of those conclusions rests on a factual judgment about the types of jobs open to such individuals, a judgment made by the Secretary after a thorough review and interpretation of the available data. 43 Fed. Reg. 55352-55355 (1978). Each also relies, however, on a policy judgment about whether the jobs an individual is capable of performing are sufficiently "significant" in number to satisfy the statutory requirement. 42 U.S.C. 423(d)(2)(A). Still a third aspect of the regulations that leads to more consistency is the fact that they incorporate a fund of knowledge about the types and numbers of jobs available that is more encyclopedic than a vocational expert's information could ever be. For example, on the basis of the available sources, and surveys prepared for SSA by various state employment agencies, the regulations take notice of some 1600 different sedentary and light occupations that can be performed after a short demonstration or within 30 days, and that do not require any special skills. 20 C.F.R. Part 404, Subpart P, App. 2, Sections 200(b), 202.00(a). Similar data support the determinations about the effects of education, work experience, and age on the types and numbers of jobs open to claimants. 43 Fed. Reg. 55353-55355 (1978). Moreover, "(t)he regulations and Appendix 2 take appropriate account of the Social Security Administration's extensive experience * * * in administering disability programs." Id. at 55362. By eliminating the need in many cases for the testimony of a vocational expert, the regulations also accomplish the twin efficiencies of reducing costs and hearing time. See page 34, supra. Of course they do not render altogether unnecessary the use of such testimony. It may still be required where the claimant suffers from a limitation, such as a mental or sensory impairment, unrelated to strength. See App. 2, Section 200.00(e); Thomas v. Schweiker, 666 F.2d 999, 1004 (5th Cir. 1982). /21/ But it is undoubtedly true that the current regulations represent a significant improvement -- in uniformity, accuracy, and efficiency -- over the former system for making disability determinations. See Cummins v. Schweiker, supra, 670 F.2d at 83 ("We think it was not only lawful * * *, but highly appropriate, for the Secretary to try to streamline the adjudication of Social Security disability cases and bring about some greater uniformity in the results of these adjudications * * * made by hundreds of different administrative law judges"). III. The Medical-Vocational Regulations Are Procedurally Fair The court of appeals did not challenge the accuracy of the job data embodied in the medical-vocational regulations. Rather, the court held that the Secretary could not rely exclusively on the regulations and Appendix 2 to direct a conclusion that respondent was not disabled because they failed "'to achieve the underlying objectives of procedural fairness to the claimant and preservation of an adequate record for review'" (Pet. App. 10a, quoting Decker v. Harris, supra, 647 F.2d at 298). Respondent has echoed that contention (Br. in Opp. 6-11), which is based on a misunderstanding of the disability review process. A. The Guidelines Provide For Individualized Consideration Of All Facts Unique To Each Claimant's Case To understand the "procedural fairness" of the tables and guidelines in Appendix 2, it is important to comprehend the process that precedes their application. Appendix 2 does not even become relevant until the last stage of the sequential disability evaluation process. It must first be determined that the claimant is not currently working, has a severe impairment (though not severe enough to be listed in Appendix 1), and is unable to perform work he has done in the past. The claimant is then given the opportunity to present, and to rebut, all relevant evidence bearing on his residual functional capacity -- which determines which one of the tables will be consulted. /22/ Similar consideration is given to a claimant's age (see J.A. 40), education (see id. at 42), and work experience (see id. at 44-47), which determine the appropriate rule to be consulted in the applicable table. /23/ The factual inquiry into each of those medical and vocational factors is not a perfunctory undertaking. Age, for example, usually is easily determined, but the regulations expressly state that age categories will not be applied "mechanically in a borderline situation." 20 C.F.R. 404.1563(a). When a claimant has (as respondent did not) skills acquired from prior work experience, the determination whether his skills are transferable (and so suit him for jobs other than those unskilled occupations underlying the tables) demands an inquiry into the degree of skill required in the other jobs, and the similarity of tools, machines, raw materials, products, processes, and services involved. 20 C.F.R. 404.1568(d)(2). In such cases, the regulations state that "we may use the services of a vocational expert or other specialist." 20 C.F.R. 404.1566(e); cf. Vazquez v. Secretary of Health and Human Services, 683 F.2d 1 (1st Cir. 1982). Education is analyzed with like flexibility. "(T)he numerical grade level that you completed in school may not represent your actual educational abilities." 20 C.F.R. 404.1564(b). Other information, such as hobbies, daily activities, and test results, are considered for the contributions they may make to "reasoning ability, communication skills, and arithmetical ability." 20 C.F.R. 404.1564(a). Not only is there a detailed factual inquiry into the characteristics analyzed in the tables, but the regulations also specifically dictate that "a conclusion of disabled or not disabled" is not directed if a claimant's vocational and medical profile is not precisely contained in Appendix 2. 20 C.F.R. Part 404, Subpart P, App. 2, Section 200.00(a), (d); 20 C.F.R. 404.1569. For example, if the claimant has an impairment unrelated to physical strength, the tables cannot be used to deny benefits. 20 C.F.R. Part 404, Subpart P, App. 2, Section 200.00(e). Such impairments would include "mental, sensory, or skin" conditions; they also encompass "(e)nvironmental restrictions * * * which result in inability to tolerate some physical feature(s) of work settings * * *, e.g., an inability to tolerate dust or fumes." Ibid. /24/ Similarly, if a claimant's impairment is exertional, but falls between the ranges indicated in the tables, the rules only offer guidance, not a fixed result. Ibid. /25/ B. A Claimant Need Not Be Given Notice And An Opportunity To Challenge The Suitability And Availability Of The Jobs Underlying The Tables The court of appeals expressed concern that a claimant be given notice and an "adequate opportunity to challenge the suitability or availability of the jobs noticed (in Appendix 2)." * * * Absent sufficient notice, the claimant is deprived of any real chance to present evidence showing that she cannot in fact perform the types of jobs that are administratively noticed by the guidelines. (Pet. App. 10a, quoting Decker v. Harris, supra, 647 F.2d at 298). Respondent, perhaps aware of the indefensibility of that position, has argued that the Secretary's burden of specifying the types of jobs available is not an evidentiary requirement, but a way (albeit mandatory) of explaining "the critical factor of residual capacity" to claimants (Br. in Opp. 9-10). We have already demonstrated that this reading is inconsistent with what the court said, with what it has done subsequently, and with the understanding of other circuits that have interpreted the opinion. Pages 9-10, supra; Reply Br. 3-4. In any event, the positions taken by the court of appeals and respondent are both without merit. 1. It is entirely unnecessary to impose on the Secretary the duty -- urged by respondent -- of illustrating the meaning of residual functional capacity by identifying specific jobs a claimant could perform. The meanings of "sedentary," "light," and "medium" work -- and of each other step in the disability determination process -- are spelled out in the regulations. See 20 C.F.R. 404.1567. The Secretary has required that those regulations be made available to claimants at district and branch offices. 20 C.F.R. 422.430(a)(3). He has also required that claimants be allowed to inspect and copy such materials as the Disability Insurance State Manual, on which state agencies rely in making initial and reconsideration decisions. 20 C.F.R. 422.430(b)(4). /26/ Claimants are entitled to be represented at hearings, a fact of which respondent was repeatedly advised. /27/ The regulations also impose on the administrative law judge an obligation "to develop a full and fair record, which * * * rises to a 'special duty . . . to scrupulously and conscientiously explore for all the relevant facts' where an unrepresented claimant has not waived counsel." Broz v. Schweiker, supra, 677 F.2d at 1364; 20 C.F.R. 404.944. The ALJ in this case fully satisfied that obligation. See pages 38-40 and notes 22, 24 supra. He concluded that respondent retained "sufficient residual functional capacity for light work" (Pet. App. 25a). His decision was upheld by the Appeals Council (id. at 17a-18a), the district court (id. at 14a), and the court of appeals (id. at 7a). There is no reason to undo that determination simply because the ALJ failed to give the type of illustration that respondent now feels would have been most satisfactory. The regulations contain no such requirement. They are fully consistent with the statute, and it is not the judicial function to rewrite them. 2. The court of appeals seemed to suggest that the Secretary must prove the existence of particular jobs so that claimants may have an opportunity to show that such jobs do not exist (Pet. App. 10a, quoting Decker v. Harris, supra, 647 F.2d at 298 (emphasis added) (the claimant must have an "adequate opportunity to challenge the * * * availability of the jobs noticed'"). But where a claimant is -- like respondent -- capable of a full range of light work, the decision about the types and numbers of jobs that exist in the national economy is particularly unsuited to adjudication. As the Seventh Circuit recently noted (Cummins v. Schweiker, supra, 670 F.2d at 83): Such a judgment, to be well informed, requires a broad knowledge of the labor market. The Department of Health and Human Services has this knowledge and can both supplement and draw upon it in a rulemaking proceeding. It was entitled to substitute an institutional judgment for the ad hoc judgments of administrative law judges based on the testimony of vocational experts and other witnesses and on their own limited and variable knowledge of the labor market. See also Torres v. Secretary of Health and Human Services, supra, 677 F.2d at 169. Unless the regulations rest on an incorrect factual basis -- and neither respondent nor the court of appeals has suggested that they do -- there are some 1600 types of unskilled jobs (i.e., jobs that can be learned by one with minimal education and skills) that exist for people (like respondent) with no physical or mental limitations other than an inability to do more than light work. To afford individual claimants a chance to dispute that proposition in case after case would uselessly consume administrative and judicial resources and would destroy the utility of the guidelines. It was well established even before the medical-vocational regulations were promulgated that, in cases like respondent's where the claimant was able to do a full range of light work, the Secretary was entitled to dispense with proof of the fact that such work existed. Breaux v. Finch, 421 F.2d 687, 689-690 (5th Cir. 1970); Mashaw, supra, at 78-80. 3. Contrary to the court of appeals' assumption, the claimant is not precluded from showing that he "cannot in fact perform the types of jobs that are administratively noticed by the guidelines" (Pet. App. 10a). One of the primary functions of the guidelines is to provide a structure that will require the ALJ to elicit all relevant information about age, education, work skills, residual functional capacity, and non-exertional limitations insofar as they bear on a claimant's ability to do the types of work underlying the tables. Moreover, before the hearing the claimant will have seen the medical and other evidence upon which the initial and reconsideration denials of his claim rested (J.A. 37). The claimant is thus free to rebut that and any other contrary evidence concerning his medical and vocational characteristics. The guidelines make this right explicit: "(E)ach of these findings of fact is subject to rebuttal and the individual may present evidence to refute such findings." 20 C.F.R. Part 404, Subpart P, App. 2, Section 200.00(a). The information that the claimant is asked to supply is not, of course, targeted at specific occupations. But in the class of cases to which the guidelines apply, that focus is unnecessary. Take respondent's situation as an illustration. What the ALJ found was that she was able to perform a wide range of unskilled light work (Pet. App. 27a) that could be undertaken "after a short demonstration or within 30 days, and (that does) not require special skills or experience." 20 C.F.R. Part 404, Subpart P, App. 2, Section 202.00(a). It was shown above (page 31) that a claimant's ability to perform light work (his exertional capacity) was not a matter about which the vocational expert testified. In that regard the guidelines effect no change from the prior system. On the other hand, it would be pointless to allow extended proof of the ways in which respondent was uneducated or unskilled, since the approximately 1600 jobs noticed in the tables presume that the claimant has no skills, and only minimal literacy and the ability to communicate in English. 20 C.F.R. 404.1564(b)(1) to (3); App. 2, Table 2, Rules 202.09, 202.10. It would be possible for a claimant to show that he could not perform many of the jobs noticed in Table 2 because he had nonexertional limitations -- e.g., an allergy to dust. But in cases (unlike respondent's) where such limitations are present, the guidelines can no longer be used to direct a conclusion of nondisability. See pages 39-40, supra. The court of appeals stated (Pet. App. 10a) that "(i)f there are so many types of jobs available, it would not be too great a burden for the Secretary or the ALJ to specify a few suitable alternative available types of jobs so that a claimant is given an opportunity to show that she is incapable of performing those jobs." But to review, one by one, the approximately 1600 jobs underlying the table applicable to respondent's case, and permit her to introduce evidence about her inability to perform each of them, would be an utterly fruitless investment of administrative resources. The very point of the guidelines is to obviate the need for such an inquiry. Once a claimant's medical and vocational characteristics have been thoroughly reviewed, then, unless the data on which the guidelines are based are seriously deficient (a point not contended in this case), it is clear that he can perform a full range of the jobs incorporated in the applicable table. 4. The court of appeals' conclusion that respondent should be allowed to dispute the availability and suitability of particular occupations not only interjects a superfluous procedure into disability hearings, but also rests on a mistaken perception of the disability determination process. The statutory term "disability" is not a historical fact that can only be ascertained on a case-by-case basis. /28/ Cummins v. Schweiker, supra, 670 F.2d at 83. Its implementation involves in the first instance a judgment about what kind of impairments -- coupled with what age, educational, and vocational characteristics -- render claimants sufficiently unable to work that they are entitled to benefits. Congress has delegated to the Secretary the responsibility of making specific the relevant medical and vocational factors, and he has done so by the regulations at issue here. "The administration of public assistance based on the use of (such) a formula is not inherently arbitrary. There are limited resources to spend on welfare. To require individual determinations of need would mandate costly fact-finding procedures that would dissipate resources that could have been spent on the needy. Sometimes, of course, Congress has required individualized findings of fact. In this case, however, the Act and legislative history make clear that Congress" both authorized and approved the Secretary's decision to proceed by general rule. Schweiker v. Gray Panthers, supra, 453 U.S. at 48 (citations and footnotes omitted). CONCLUSION The judgment of the court of appeals should be reversed. Respectfully submitted. REX E. LEE Solicitor General J. PAUL McGRATH Assistant Attorney General KENNETH S. GELLER Deputy Solicitor General JOHN H. GARVEY Assistant to the Solicitor General ROBERT S. GREENSPAN ANNE BUXTON SOBOL Attorneys SEPTEMBER 1982 /1/ The Act's definition of disability is the same for both the Federal Old-Age, Survivors, and Disability Insurance program (Title II) and the Supplemental Security Income ( SSI") program (Title XVI). Compare Section 223(d) of Title II, 42 U.S.C. (& Supp. IV) 423(d), with Section 1614(a)(3) of Title XVI, 42 U.S.C. (& Supp. IV) 1382c(a)(3). The medical-vocational regulations apply to disability determinations under both programs: 20 C.F.R. Part 404, Subpart P governs Title II Claims; 20 C.F.R. Part 416, Subpart I, which is virtually identical to Subpart P, applies to SSI claims, 20 C.F.R. 416.969. Respondent claimed benefits only under Title II. /2/Numerous public interest groups participated in this phase of the rulemaking process. See 42 Fed. Reg. 8223 (1977); 41 Fed. Reg. 51471 (1976). /3/ The agency later rewrote the regulations to make them clearer and easier to use. 45 Fed. Reg. 55566 (1980). /4/ There are four levels of administrative consideration of disability claims. The first two levels of decision, the initial and reconsideration determinations, are made by state agencies. 42 U.S.C. (Supp. IV) 421(a). The third level of the administrative process is a hearing before an administrative law judge in the Social Security Administration. 42 U.S.C. (Supp. IV) 405(b), 421(d). The fourth level is review by the Appeals Council of the Social Security Administration. Judicial review of the final administrative decision is authorized by 42 U.S.C. (Supp. IV) 405(g), 421(d). See Califano v. Sanders, 430 U.S. 99, 101-102 (1977). /5/ The term "regulations" will generally be used to refer to 20 C.F.R. Part 404, Subpart P in its entirety. Subpart P includes, following 20 C.F.R. 404.1598, two appendices. Appendix 1 is a listing of impairments that are considered presumptively disabling. Appendix 2 is entitled "Medical-Vocational Guidelines" and will generally be referred to as the "guidelines" or "Appendix 2." Within Appendix 2 are various "tables" directing disability outcomes according to claimants' residual functional capacity. Each of the tables contains a number of "rules" for different combinations of age, education, and work experience. See Pet. App. 35a-75a. /6/ The sources of data on the numbers of unskilled jobs and the vocational significance of age, education, and work experience are set forth in the preamble to the regulations, 43 Fed. Reg. 55352-55355 (1978), and in the text of the regulations, 20 C.F.R. 404.1566(d) (job data); App. 2, Section 200.00(b) (job data). For example, the determinations about unskilled jobs at various levels are "supported by the 'Dictionary of Occupational Titles' and the 'Occupational Outlook Handbook,' published by the Department of Labor; the 'County Business Patterns' and 'Census Surveys' published by the Bureau of the Census; and occupational surveys of light and sedentary jobs prepared for the Social Security Administration by various State emploment agencies." 20 C.F.R. Part 404, Subpart P, App. 2, Section 200.00(b). As later editions of these publications become available -- e.g., the fourth edition of the Dictionary of Occupational Titles (1977), recently published by the Department of Labor -- the guidelines will be updated to incorporate them. 43 Fed. Reg. 55351 (1978); cf. Sherwin v. Secretary of Health and Human Services, No. 81-1885 (1st Cir. June 22, 1982), slip op. 8-9. The guidelines also include a detailed textual statement that explains and justifies the tables and rules in Appendix 2 (Pet. App. 52a-75a). /7/ On April 28, 1982, the agency adjudicated a claim for disability benefits filed by respondent on February 9, 1982. The agency found respondent disabled as of January 1, 1981 on the basis of a change in her condition. The decision on respondent's subsequent claim has no effect on her right to benefits through December 31, 1980, the date of the agency's final decision on the claim now before this Court. See 42 U.S.C. 405(h); 20 C.F.R. 404.957(c)(1); Califano v. Sanders, 430 U.S. 99 (1977). /8/ The court did state that "(i)n failing to show suitable available alternative jobs for Ms. Campbell, the Secretary's finding of 'not disabled' is not supported by substantial evidence" (Pet. App. 11a). That criticism evidently applies to the adjudication of respondent's claim, rather than to the rulemaking proceeding that resulted in promulgation of the regulations. Cf. 5 U.S.C. 706(2)(E). But the evidence that the court found lacking was rendered unnecessary by the regulations, so its absence is significant only if the regulations are invalid. /9/ Provisions comparable to Sections 405(a) and 423(d)(5) are found in Title XVI. See 42 U.S.C. 1383(d)(1), (e)(1). /10/ Section 423(d)(4) also provides that there shall be excluded from earnings the cost of services, devices, and drugs "which are necessary (as determined by the Secretary in regulations)" to enable the individual to work, and "that the amounts to be excluded shall be subject to such reasonable limits as the Secretary may prescribe." /11/ In Broz the court sustained the Secretary's authority to enact regulations specifying the effect of residual functional capacity, education, and work experience on a claimant's ability to engage in substantial gainful work, but held that individualized consideration must be given to the effect of age on disability claimants. 677 F.2d at 1359-1361. /12/ Unskilled jobs are those that "can be performed after a short demonstration or within 30 days, and do not require special skills or experience." 20 C.F.R. Part 404, Subpart P, App. 2, Section 202.00(a). /13/ In 1954 Congress created a "freeze" program perpetuating coverage of workers during periods of disability when they were unable to continue paying into the Social Security system. Social Security Amendments of 1954, ch. 1206, Section 106, 68 Stat. 1080. In 1956 Congress authorized the payment of benefits to disabled workers at age 50. Social Security Amendments of 1956, ch. 836, Section 103, 70 Stat. 815. In 1958 benefits were extended to the dependents of disabled workers. Social Security Amendments of 1958, Pub. L. No. 85-840, Section 205, 72 Stat. 1021. In 1960 Congress extended eligibility for benefits to disabled workers below age 50. Social Security Amendments of 1960, Pub. L. No. 86-778, Section 401, 74 Stat. 967. /14/ The currently effective provision, cited in text, differs in respects not here relevant from that enacted in 1954. /15/ Pub. L. No. 97-123, Section 6, 95 Stat. 1664 (Section 423(f)); Pub. L. No. 96-473, Section 5(a)(1), (c), 94 Stat. 2264, 2265 (Section 423(d)(6), (f)); Pub. L.

No. 94-455, Title XII, Section 211(b), 90 Stat. 1711 (Section 405(c)(2)). /16/ The Disability Insurance State Manual included Disability Insurance Letters like that cited in text. The same materials were included in the Bureau of Disability Insurance, Vocational Specialist Training Handbook, cited below. Copies of relevant portions of the Vocational Specialist Training Handbook, including DIL No. III-3, have been lodged with the Court and furnished to counsel for petitioner. /17/ The Vocational Specialist Training Handbook was used by SSA to train vocational specialists within each state office responsible for making the initial and reconsideration decisions. Such state offices were established by agreement between the state and the Secretary, 42 U.S.C. 421(b), and were reimbursed for their services out of trust funds. 42 U.S.C. 421(e). Sections 421(b) and 421(e) have since been amended. /18/ Both the Disability Insurance State Manual and the Vocational Specialist Training Handbook, in assessing the significance of the vocational factors, relied upon many of the sources underlying the medical-vocational regulations, such as the Dictionary of Occupational Titles, supra, the Bureau of Labor Statistics, Occupational Outlook Handbook; Bureau of the Census, County Business Patterns; and the Bureau of the Census, Census Reports; 43 Fed. Reg. 55350-55351 (1978); Training Handbook, supra, at 5-1 to 5-6. /19/ See note 18, supra. These materials are also among those of which the current regulations take administrative notice. 20 C.F.R. 404.1566(d); Kirk v. Secretary of Health and Human Services, supra, 667 F.2d at 530. /20/ Every job involves various physical demands, such as strength (exertion), balancing, stooping, manual dexterity, and aural and visual acuity. Moreover, jobs are performed under a variety of different working conditions: they may be indoors or outdoors, subject to extremes of temperature, humidity, noise, toxic conditions, or other hazards. They may also require an applicant to have more or less education or vocational training. For example, operating a dough mixer in the baking industry is classified as light work, but it involves stooping or crouching, as well as a degree of manual dexterity. The job is also performed in conditions that are often hot, humid, and dusty. The training required to undertake the job may last from six months to a year. Department of Labor, Selected Characteristics of Occupations Defined in the Dictionary of Occupational Titles 129 (1981). By contrast, the job of garment bagger in the laundry industry -- also classified as light work -- involves no additional physical demands other than some manual dexterity. The job is not performed under any unusual environmental conditions and can be learned after only a brief demonstration. Id. at 212. /21/ Moreover, expert testimony may be desirable for deciding some difficult questions that can arise under the guidelines. One such issue is whether a particular claimant's skills are transferable to a relatively wide range of jobs. 20 C.F.R. 404.1566(e); McCoy v. Schweiker, supra, 683 F.2d at 1141 n.1. Compare App. 2, Table 1, Rule 201.14 with Rule 201.15. /22/ "Light work" (the table applied in respondent's case), for example, is described as involv(ing) lifting no more than 20 pounds at a time with frequent lifting or carrying of objects weighing up to 10 pounds. * * * (A) job is in this category when it requires a good deal of walking or standing, or when it involves sitting most of the time with some pushing and pulling or arm or leg controls. 20 C.F.R. 404.1567(b). At her hearing respondent introduced evidence on each of those facts. J.A. 21, 28-29, 31-33, 46-51. She was also instructed by the administrative law judge at the beginning of the hearing that he would "take * * * evidence on your residual functional capacity to engage in sedentary, light, medium, or heavy work. This essentially (is) * * * your ability to walk, stand, sit, lift, push, pull or carry." Id. at 37. /23/ The circuits that have upheld the regulations have recognized that an ALJ's decision is not supported by substantial evidence if it does not establish each of these factors. See, e.g., Spencer v. Schweiker, 678 F.2d 42, 44-45 (5th Cir. 1982) (no substantial evidence supporting ALJ's conclusion that claimant could do sedentary work); Dodgins v. Schweiker, 681 F.2d 813 (4th Cir. 1982) (light work). /24/ In this case the administrative law judge specifically questioned respondent about the nonexertional impairments she might have. J.A. 39 ("If your case does not fall under a particular rule or you have some non-exertional impairments, the rule will be used as a frame of reference to determine whether you are disabled"), 40-41, 47-54 (Q. "You have told me just about your medical problem, have you not, as you understand it to be?" A. "I think so, sir. * * * I don't think I forget anything.") Even the circuits that have upheld the regulations have been careful to find that the tables may not be used where a claimant has some significant nonexertional impairment. Burnam v. Schweiker, 682 F.2d 456, 458 (3d Cir. 1982); McClenny v. Harris, 681 F.2d 814 (4th Cir. 1982); Thomas v. Schweiker, supra, 666 F.2d at 1004 (sensitivity to dust, heat, fumes); Roberts v. Schweiker, 667 F.2d 1143, 1145 (4th Cir. 1981) (sensitivity to lint); Torres v. Secretary of Health and Human Services, 668 F.2d 67, 69 (1st Cir. 1981) (psychiatric impairment); Cannon v. Harris, 651 F.2d 513, 518-520 (7th Cir. 1981) (alcoholism); Gagnon v. Secretary of Health and Human Services, 666 F.2d 662, 666 n.8 (1st Cir. 1981) (pain). /25/ 20 C.F.R. Part 404, Subpart P, App. 2, Section 201.00(h) gives the following example: Example 1: An individual under age 45 with a high school education can no longer do past work and is restricted to unskilled sedentary jobs because of a severe medically determinable cardiovascular impairment (which does not meet or equal the listings in Appendix 1). A permanent injury of the right hand limits the individual to sedentary jobs which do not require bilateral manual dexterity. None of the rules in Appendix 2 are applicable to this particular set of facts, because this individual cannot perform the full range of work defined as sedentary. Since the inability to perform jobs requiring bilateral manual dexterity significantly compromises the only range of work for which the individual is otherwise qualified (i.e., sedentary), a finding of disabled would be appropriate. /26/ We are informed by the Secretary that the Notice of Hearing sent to claimants is accompanied by Form HA-4607, which states that Appendix 2 will be considered in making the disability determination. Form HA-4607 also outlines the sequential disability evaluation process. The Form is reproduced in the Appendix to this brief. /27/ See, e.g., J.A. 36: Q. All right. I might say this to you. If you want legal assistance or help and they are busy now, the case could be put off at a later time and whenever they could represent you. But if you want to go forward today and see what the evidence is and see if you need -- need a representative, we are ready to do so. A. I'm willing to go forward. /28/ The disability insurance system should not be confused with unemployment compensation. The issue in disability cases is not whether the claimant has sought and been unable to find a job. Appendix Omitted
