Federal Information Processing Standards Publications (FIPS PUBS) are issued by the National Institute of Standards and Technology after approval by the Secretary of Commerce pursuant to Section 111(d) of the Federal Property and Administrative Services Act of 1949, as amended by the Computer Security Act of 1987, Public Law 100-235.

1.Name of Guideline.Codes for Named Populated Places, Primary County Divisions, and Other Locational Entities of the United States, Puerto Rico, and the Outlying Areas.

2.Category of Guideline.Data Standards and Guidelines, Representations and Codes.

3.Explanation.Federal Information Processing Standard (FIPS) 55-3 provides codes for named popu lated places, primary county divisions (such as townships and census county divisions), American Indian and Alaska Native areas, and several kinds of facilities. It also provides comparable codes for counties and equivalent legal and statistical entities. In addition to the entity name and its code, the guideline provides other identifying and cross-reference information for each file entry. This guideline covers the 50 States, the District of Columbia, Puerto Rico, and the outlying areas (American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, the Virgin Islands of the United States, and United States Minor Outlying Islands) and freely associated areas (the Federated States of Micronesia, the Marshall Islands and the Republic of Palau) of the United States.

For each State, the District of Columbia, Puerto Rico, and outlying areas, the guideline records all incorporated places, census designated places, county subdivisions, counties and statistically equivalent entities and their primary divisions as recognized by the U.S. Bureau of the Census. It also includes all American Indian and Alaska Native areas included in the last census, and a list of many other named populated locations. Among the facilities included are national parks, military installations, Coast Guard bases, and major airports. The guideline provides a class designator, or code, for each entry to distinguish populated places, county subdivisions, counties, American Indian and Alaska Native areas, selected facili ties, and obsolete and unverified names. The class code structure also provides subcategories that distin guish active local governments from those that are inactive or nonfunctioning, various types of populated places and Federally and State recognized American Indian and Alaska Native entities, several types of government facilities, and so forth.

FIPS 55-3 supersedes FIPS 55-2 in its entirety and incorporates technical changes that have been issued by the U.S. Geological Survey, Department of the Interior, and the Bureau of the Census, Department of Commerce. Several categories of locational entities have been dropped in FIPS 55-3; these are documented in the text. In addition, the text of FIPS 55-3 contains minor editorial changes and updates from the text of FIPS 55-2.

4.Approving Authority.U.S. Department of Commerce, National Institute of Standards and Technology (Computer Systems Laboratory).

The files of Federal Information Processing Standards Publication (FIPS PUB) 55 provide a unique code for each listed populated place, primary county division, and other locational entity in the 50 States, the District of Columbia, Puerto Rico and the Outlying Areas. (References to ``State'' in this standard also apply to the District of Columbia, Puerto Rico, and each Outlying Area including the freely associated areas.) The file contains approximately 195,000 individual entities. The unique code combination consists of a 2-digit numeric State Code (as specified in FIPS PUB 5-2) and a 5-digit numeric FIPS entity code (as specified in this FIPS PUB). The entity code sequence is repeated for each State, so that an entity code requires the FIPS State code to identify each entity uniquely. For example, the city of Modesto, California is distinguished from all other places in the Nation by its 7-digit code, 0648354, in which ``06'' represents the State of California and ``48354'' uniquely identifies Modesto within that State. In addition to the State and entity codes, the record for each entity contains several related items of information for that entity.

1.1Main Alphabet Sequence

Records are listed numerically by FIPS place code within each State. The lowest-numbered entity code is assigned to the first entity in alphabetical sequence for each State. Successively assigned entity codes increase in numerical value as entity names progress in alphabetic order. The entity code assigned to the last entity in the main alphabetic sequence does not exceed 89999. This correspondence between alphabetic order and entity code sequence facilitates alphabetic sorting by permitting an alternate numeric sort on fewer characters. The alphabetic sequence is standard and represents the order a word would appear if all spaces and punctuation were removed. Characters within parentheses are ignored. The alphabetization is for the complete spelling of abbreviated entity names that may appear in the file, for example, Mt. Pleasant will be alphabetized as if unabbreviated as Mount Pleasant. There is a notable exception. Words beginning with the letters ``Mc'' are alphabetized as if spelled ``Mac''. Different entities with the same name are sorted by county code; if more than one entity of the same name exists in a single county, generally entities in Group 1 of the class code structure have a lower value than Group 2 class code entities, and so on. Some entities contain numeric characters; a numeric character string is treated as a single character, thus an entity name followed by a number 2 sorts earlier in the alphanumeric sort than the same name followed by a 10.

The codes assigned to the original set of entities in the main sequence for each State provided for a standard numerical increment between successive codes. The lone exception was the assignment of codes to the most well-known places; codes assigned to such places usually end in ``00'' or ``000,'' necessitating a larger-than-standard increment. In a State with a smaller number of entities, the standard increment between successive place codes is larger, while in a State with a larger number of entities, the standard increment between successive place codes is smaller. Thus, place codes are nearly uniformly distributed between the limits of the main sequence. The State with the largest number of entities is Pennsylvania; accordingly, it has the smallest standard increment, eight. The numeric gap between entity codes allows for the insertion of additional records in proper alphabetic sequence with code assignments that retain the ascending numerical sequence. As a result of entities being added since the original code assignment, the increment between some place codes will be smaller than the initial standard increment. In a very small number of instances since FIPS PUB 55-2, new entity records required recoding of existing records to maintain the alphanumeric sort.

1.2Inactive and Nonfunctioning Primary County Divisions

A second sequence of codes provides assignments for selected types of inactive, nonfunctioning, or statistical primary county divisions not listed in the main sequence. This sequence begins after entity code 90000 and does not exceed 97999. There may be two or more separate sets of entities and codes in this second sequence, such as the townships followed by the census county divisions in Nevada. Eighteen States do not have a second sequence at this time: Alaska, Connecticut, Indiana, Kansas, Massachusetts, Michi gan, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota, Vermont, and Wisconsin. The second sequence also is not used in Puerto Rico or any of the Outlying Areas.

In this sequence, as in the main sequence, entities are spaced in equal numerical increments between the limiting place codes, except where entities have been added to the original version of this file. Again, in States with many entities, the numeric difference between successive codes is less than in States with fewer entities. And in some instances since FIPS PUB 55-2, new entity records required recoding of existing records to maintain alphanumeric sort.

1.3Counties and Statistically Equivalent Entities

Another sequence of codes begins at or after 99001 in the file for each State. This sequence assigns a 5-digit FIPS 55 code to each county and statistically equivalent entity. The code consists of 99 followed by the 3-digit county code specified in FIPS PUB 6-4. For example, Autauga County, Alabama, with a county code of 001, is assigned a FIPS 55 code of 99001 in the Alabama file; Montgomery County, Maryland, with a county code of 031, is assigned a FIPS 55 code of 99031 in the Maryland file. This sequence is provided so that every local governmental unit, including counties, can be assigned a compatible 7-digit code. In addition, these records provide summarized information about the metropolitan area(s) and 103rd Congress congressional district(s) (CD) in which each county is located.

The sequence commencing at 99001 does NOT apply to the independent cities of Baltimore (city), Maryland; St. Louis (city), Missouri; Carson City, Nevada; and the 41 independent cities in Virginia. The county-equivalent codes assigned to these cities in FIPS PUB 6-4 are NOT used to create FIPS 55 codes because appropriate place codes are already assigned to the independent cities in the main sequence of this FIPS PUB.

1.4Data Included for Each Entity

Some of the data included for each entity in the file, in addition to its name and FIPS entity code, are the FIPS PUB 5-2 State code and the State postal abbreviation, the name and FIPS PUB 6-4 code of each county in which the entity is located, a class code (see Section 5) that identifies the type of entity, the ZIP Code (or code range) if the entity name also is the name of a post office, and a cross-reference to the Worldwide Geographic Location Codes issued by the U.S. General Services Administration. The ``Part of Code'' and ``Other Name Code'' fields provide for the identification of relationships between entities.

Additional data are included for each entity that represents a county, primary county division, incorpo rated place, census designated place, American Indian area, or Alaska Native area. For these entities, the CD(s) in which each is located is identified; the data reflect the reapportionment and redistricting for the 103rd Congress, whose term began in January 1993 and ended in January 1995. Also, for any entity located in a metropolitan statistical area or primary metropolitan statistical area, the code for that area is shown. For incorporated and census designated places and for American Indian/Alaska Native areas, the code assigned by the U.S. Bureau of the Census is listed. (Note that the Census Bureau plans to use only the FIPS 55 codes for these entities, beginning with the 1997 economic censuses and the 2000 decennial census.)

Four indexing fields are used on the tape, but are not printed in the hard-copy version. Section 4 provides a complete list of fields and their locations in each tape record and in the printed version.

Files are recorded on a single, standard 9-track tape at a density of 1600 bpi, odd parity. There are 64 logical records per physical record (8448 characters per block). Both ASCII and EBCDIC versions are available. Both versions are upper- and lower-case characters. Tapes are unlabeled.

3.1File Format

The FIPS 55 file is subdivided into 60 individual filesone for each State, the District of Columbia, Puerto Rico, and each Outlying Areaon a single reel of tape. This offers access to any State or statistically equivalent entity. The files are sequenced in numerical order based on the FIPS State codes; that is, the States and the District of Columbia occur first in alphabetical sequence, followed by Puerto Rico and the Outlying Areas in alphabetical sequence. The sequence, number of entities, and number of records in each file are listed in Table 1 (pp. 2526).

3.2Record Format

The record length is fixed at 132 characters. Entities that are located in only one county and in not more than three CDs require only one 132-character record; 99 percent of all entities require only one record. The remaining entities require more than one 132-character record because they are located in more than one county or in more than three CDs in a single county.

Data that are constant for an entity are repeated in each tape record for that entity (but are not repeated in the printed version). Any data for an entity can vary between counties except the FIPS State code, State abbreviation, entity code, and entity name.

Only one record format is used, regardless of how many records each entity requires. To provide for the possibility of a variable number of records per entity, the computer file uses four indexing fields. Two indexing fields are associated with additional records for CDs in one county and two fields relate to additional records for counties.

• To allow for more than three CDs in a single county, there are a 2-digit indexing field named ``Total Number of CDs'' and a 1-digit indexing field named ``CD Record Sequence Number.'' For example, in a county that is located in eight CDs, the first field would be set to ``8'' and the second field would be set to ``1,'' ``2,'' and ``3,'' respectively, in the first of the three successive records required to store the eight CD codes. The system allows for up to 27 CDs in a single entitymore than any entity currently requires.
  
  
• To allow for more than one county for an entity, a 2-digit indexing field named ``Total Number of Counties'' identifies how many counties each entity requires. Another 2-digit field, ``County Sequence Number,'' identifies the county sequence of the current record in the set of records for the entity. There will be more than one record with the same county sequence number if more than three CDs are listed for that county.

Note:``Location'' applies to the tape version only; ``Printed version'' identifies the placement of fields in the hard copy.

The following definitions are provided to facilitate understanding of the class code system.

active:Refers to a governmental unit (county or statistically equivalent area, minor civil division, consolidated city, or incorporated place) that exercises its legally constituted governmental functions and powers; see inactive and nonfunctioning.

Alaska Native Area: a)A legal entity recognized by the Federal Government pursuant to the Alaska Native Claims Settlement Act. These are the Alaska Native Regional Corporation (ANRC) and Alaska Native Village (ANV). Or a statistical entity that identifies the settled portion of the Alaska Native tribes, delineated for purposes of data presentation by or for the Census Bureauthis is the Alaska Native Village statistical area (ANVSA). b)a legal entity recognized by the Federal Government persuant to Alaska Native Claims settlement Act to conduct the business and nonprofit affairs for Alaskathis is the Alaska Native Regional Corporation.

American Indian Area: a)A legal entity with specific boundaries established by treaty, statute, and/or executive order, over which a Federally recognized American Indian trive has jurisdiction. This area is called an American Indian reservation, but includes entities with other designations such as pueblo, colony, and community; b)a legal entity for which lands are held in trust by the Federal Government for the use and benefit of a tribe or individual member of a tribethis is called trust land, either tribal or individual; c) a legal entity with specific boundaries established by state statute for a state-recognized American tribethis is called a state American Indian reservation; d) a statistical entity delineated for the purposes of data tabulation by or for the Census Bureau that delimits the population and area over which one or more American Indian tribes lacking a reservation have jurisdiction and/or provide benefits and services to members of the tribe this is called a tribal jurisdictional statistical area in Oklahoma, and tribal designated statistical area in other states.

authoritative common name:A name in common use and approved by an authoritative body such as the U.S. Board on Geographic Names.

census county division (CCD):A statistical entity that serves as a primary county division in 21 States that do not have minor civil divisions (MCDs) or whose MCDs are not used for data presentation by the Census Bureau.

census designated place (CDP):A statistical entity that represents a named populated settlement, not within the limits of an incorporated place, that has locally delineated boundaries and is recognized by the Census Bureau in the data tabulations for the most recent decennial census; in Puerto Rico the equivalent of a CDP is called a comunidad or zona urbana.

census subarea:A statistical entity that serves as a primary county division in Alaska.

census subdistrict:A legally defined entity, established for statistical purposes, that serves as a primary county division in the Virgin Islands of the United States.

community:A populated place that is not an incorporated or census designated place of the same name; includes neighborhood areas within an incorporated or census designated place with a different name and all types of named settlements.

county equivalent:A primary division of a State or a State equivalent; other than a county; for example, a parish in Louisiana, a borough or census area in Alaska, or an independent city in Maryland, Missouri, Nevada, or Virginia.

facility:A locational entity, established as a site for designated activities but not primarily for habitation (even though on-site habitation may be necessary to the execution of the primary activities); for example, a college, hospital, military installation, national park, office building, or prison.

inactive:Refers to a governmental unit (county or statistically equivalent areas, minor civil division, consolidated city, or incorporated place that has legally constituted governmental functions and powers, but currently does not exercise them; see active and nonfunctioning.

incorporated place:A populated place that is a legal entity having legally defined boundaries and legally constituted governmental functions and powers; also serves as a primary county division in some States.

independent city:An incorporated place that is not legally part of a county or county equivalent and, therefore, also serves as a county equivalent; applies only to Maryland, Missouri, Nevada, and Virginia.

independent place:An incorporated place that is also a primary county division.

minor civil division (MCD):A legal entity that is a subdivision of a county or county equivalent, other than an incorporated place, established by appropriate State or local governmental authorities and recog nized by the Census Bureau as a primary county division; for example, a township in Ohio, a town in Vermont, a magisterial district in Virginia. The Census Bureau recognizes MCDs in 28 States, Puerto Rico, and in all the Outlying Areas and freely associated areas.

nonfunctioning:A legal entity (county, or statistically equivalent area, minor civil division, or incorpo rated place that does not have legally constituted governmental functions and powers and cannot have elected officials; see active and inactive.

nonplace:A term that modifies the set of county equivalents and primary county divisions so as to exclude from membership all incorporated places and census designated places.

populated place:A named geographic concentration of residential population; a populated place that is a legal entity is an incorporated place or consolidated city; a populated place that is a statistical entity is a census designated place (aldea or zona urbana in Puerto Rico); a populated place that is neither is a community.

primary county division:The principal territorial unit into which a county or county equivalent (except an independent city) is completely subdivided, without overlap; see census county division, census subarea, census subdistrict, incorporated place, minor civil division, and unorganized territory.

State equivalent:The District of Columbia, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, Puerto Rico, United States Minor Outlying Islands, and the Virgin Islands of the United States; three freely associated statesthe Federated States of Micronesia, Republic of the Marshall Islandsand the Republic of Palau, also are defined as State equivalents for this FIPS.

unorganized territory (UNORG):A statistical entity established within a portion of a county or county equivalent that is not subdivided into minor civil divisions or part of an incorporated place that is also a primary county division or in an independent city, for the purposes of data presentation of the Census Bureau; occurs only in those States that have minor civil divisions, and always serves as a primary county division.

5.2Entity Selection With the Aid of the Class Code

Each file entity record is assigned a 2-character class code that distinguishes the type of entity. The first character is alphabetic and identifies a class. The second character either is blank if a class has no subclasses, or is a digit from 1 to 9 that identifies a subclass. See Section 5.3.

legal entity:a geographic unit with legally defined boundaries established under Federal, State, or local law as a government unit or as an area for the administration of a governmental function.

statistical entity:a geographic unit established for the purposes of data presentation by the Census Bureau that has no legally defined boundaries or governmental function.

governmental unit:a geographic entity that has the ability to have elected officials and raise revenues through taxes; see active and inactive.

The primary function of the class code structure is to distinguish different types of entities, such as counties, primary county divisions, and populated places. These three types generally form a hierarchy; that is, a county (or county equivalent) will contain one or more primary county divisions, while a primary county division may include one or more populated places. Some populated places, however, also serve as primary county divisions, and a few also serve as county equivalents. Some are coextensive with their primary county divisions. For each of these types of entities, the class code structure distinguishes the type of entity, whether it has a special relationship to another type of entity, and whether it is a legal entity (active, inactive, or nonfunctioning entity), a statistical entity, or another type of locational entity. For example, among the primary county divisions, the active governmental units are identified by two subclasses in Class T; for populated places, the active governmental units are identified as incorporated places and distinguished by several of the subclasses in Class C.

The class code structure is extremely important in distinguishing entities that have the same or a similar name and may be located in the same county. Below is an example from the Michigan file:

      Entity    Entity                 County    County         Class      Code      Name                   Code      Name           Code      51620     Marion (Township of)   029       Charlevoix     T1      51640     Marion (Township of)   093       Livingston     T1      51660     Marion                 133       Osceola        C1      51680     Marion (Township of)   133       Osceola        T1      51700     Marion (Township of)   145       Saginaw        T1      51720     Marion (Township of)   151       Sanilac        T1      51740     Marion Springs         145       Saginaw        U6 

The importance of the same name applying to multiple records in the same county takes on more importance as the class codes contain information about the realtionships between entities. As an example of the use of the class code in distinguishing between an incorporated place and a primary county division where the class code includes some determined relationship information between entity types, consider these data for two records in New York:

      Entity    Entity                 County    County         Class      Code      Name                   Code      Name           Code      30521     Green Island           001       Albany         C1      30532     Green Island (Town of) 001       Albany         T5    

An apparently similar situation exists in Wisconsin, as shown in the following example:

      Entity    Entity                 County    County         Class      Code      Name                   Code      Name           Code      48000     Madison                025       Dane           C5      48025     Madison (Town of)      025       Dane           T1    

A slightly different situation exists with the following two records in Massachusetts:

      Entity    Entity                 County    County         Class      Code      Name                   Code      Name           Code      09175     Brookline (Town of)    021       Norfolk        T1      09210     Brookline              021       Norfolk        U1    

The class code structure also is useful to distinguish alternate names for the same incorporated place. The Census Bureau identifies each incorporated place by its legal corporate name, as reported by State and local officials. In some instances, the place is commonly known by another name that may be very similar. For example, consider this pair of records in Alabama.

                                                                   Other      Entity    Entity                 County    County   Class     Name      Code      Name                   Code      Name     Code      Code      55824     Oakhill                131       Wilcox   C4        55848                (corporate name Oak Hill)      55848     Oak Hill               131       Wilcox   C1        55824                (corporate name for Oakhill) 

The class code can be useful in selecting a portion of a single entity with a particular status, as shown by this example in California:

      Entity    Entity                 County    County         Class      Code      Name                   Code      Name           Code      21600     Edwards Air Force Base 029       Kern           M2                                       037       Los Angeles    M1                                       071       San Bernadino  M1 

A similar situation occurs in this example in Ohio:

      Entity    Entity                 County    County         Class      Code      Name                   Code      Name           Code      36918     Hunting Valley         035       Cuyahoga       C5                                       055       Geauga         C1 

5.3Class Code Structure

Each class is included in one of five major groups: populated places not associated with facilities; counties and county equivalents, primary county divisions, and American Indian areas and Alaska Native areas; facilities other than communications and transportation; communications and transportation facili tates; and obsolete or incorrect names. The groups identify the distinctions among populated settlements, areally larger units that tend not to represent a cluster of population, a variety of facilities, and the inevitable other category. Some class codes are new for FIPS 55-3, and some categories recognized in previous versions of FIPS 55 have been dropped or revised; these changes are noted in the text.

The subclasses provide the ability to relate an entity to a class other than its own. This ability is useful because a number of entities serve in more than one capacity. For example, a military base may also serve as a commercial airport, and an American Indian reservation may also serve as a primary county division. Similarly, it is useful to identify close relationships through this method. A number of subclasses identify entities in different classes that are coextensive or approximately so, such as a place that is coextensive with a minor civil division or an Alaska Native Village statistical area. There also are subclasses that identify alternate names for the same entity. The groups, classes, and subclasses are described below.

5.3.1Group 1:Populated Places Not Associated With Facilities

Class C:Incorporated Places

Names appearing in this class are those recognized by the U.S. Bureau of the Census based on information provided by State, county, and local governments. Alternate authoritative common names recog nized by the U.S. Board on Geographic Names are recorded in subclass C4.

C1:Identifies an active incorporated place that is not also recognized as an Alaska Native Village statistical area, and does not also serve as a primary county division; that is, it is included in and is part of a primary county division. For example, the city of Hammond, Indiana is within and part of North township; the city of Austin, Texas is within and part of several census county divisions in several counties; Hammond and Austin are coded C1.

C2:Identifies an incorporated place that also serves as a primary county division because, although the place is coextensive with a minor civil division (MCD), the Census Bureau, in agreement with State officials, does not recognize the MCD for presenting census data because the MCD is a nonfunctioning entity; applies to Iowa and Ohio only. For example, the city of Dubuque, Iowa is coextensive with Julien township, which does not function as a governmental unit and may not be well-known even to local residents; the city is assigned code C2, and the township, Z8. This subclass is new for FIPS 55-3. Also see subclass C5.

C3:Identifies a consolidated city; that is, an incorporated place that has consolidated its governmental functions with a county or MCD, but continues to include other incorporated places that are legally part of the consolidated government. For example, the city of Columbus, Georgia is consolidated with Muscogee County, which continues to exist as a nonfunctioning legal entity in the State; however, the town of Bibb City continues to exist as a separate active incorporated place within the consolidated government and, therefore, Columbus is treated as a consolidated city. At the time of publication, there are seven consolidated cities in the United States: Athens-Clarke County, Georgia; Butte-Silver Bow, Montana; Columbus, Georgia; Indiana polis, Indiana; Jacksonville, Florida; Milford, Connecticut; and Nashville-Davidson, Tennessee. The subclass is new for FIPS 55-3.

C4:Identifies an alternate authoritative common name of any member of the other subclasses of Class C. The entity code of the legal name is referenced in the ``Other Name Code'' of the record, and in the entry for the legal name, the Other Name Code references the alternate. For example, the entity in California whose legal name is San Buenaventura (subclass C1) is commonly known as Ventura, which is coded C4.

C5:Identifies an incorporated place that also serves as a primary county division; that is, it is not included in any adjacent primary county division of class T or Z. For example, Boston, MA, is legally a primary division of the county and recognized as an incorporated place and, therefore, is coded C5. Also see subclass C2.

C6:Identifies an incorporated place that is coincident with or approximates an Alaska Native Village statistical area. The Other Name Code references the Alaska Native Village statistical area; see subclass E6.

C7:Identifies an independent city. At the time of publication, independent cities exist in only four States: Maryland (Baltimore City), Nevada (Carson City), Missouri (St Louis City), and Virginia (41 cities). These cities also serve as county equivalents, and all but Carson City also serve as primary county divisions.

C8:Identifies the portion of a consolidated city that is not within another incorporated place; see subclass C3. The Census Bureau identifies these nonfunctioning entities by taking the name of the consol idated city and appending in parentheses the word remainder. For example, Columbus (remainder) identifies the portion of the Columbus, Georgia consolidated city that is not also in Bibb City. This subclass is new for FIPS 55-3.

C9:Identifies an inactive or nonfunctioning incorporated place.

U1:Identifies a census designated place (CDP) with a name identical to the authoritative common name that describes essentially the same population. Also see subclass M2.

U2:Identifies a CDP with a name not identical to an authoritative common name of essentially the same area. If there is an alternate authoritative common name, it is referenced in the Other Name Code field. For example, Suitland-Silver Hill, Maryland is the name of a locally delineated CDP recognized by the Census Bureau which is a combination of two communitiesSuitland and Silver Hilland, therefore, because it is not the authoritative name of the area, is coded U2; Sierra Vista Southeast, Arizona is a CDP that includes the built-up area adjoining the city of Sierra Vista on the southeast, but is not an authoritative name for that area and, therefore, is coded U2. Also see subclass M2.

U3:Identifies (a) an alternate, authoritative common name of a population essentially described by a specific CDP with a different name (the Other Name Code references the CDP), or (b) a community wholly or substantially within the boundaries of a CDP with a different name (the Part of Code references the CDP). For example, Silver Hill and Suitland are coded U3 and cross-referenced to the CDP of Suitland-Silver Hill (see subclass U2).

U4:Identifies a populated place wholly or substantially within the boundaries of an incorporated place with a different name; the Part of Code identifies the incorporated place. For example, Harlem and Greenwich Village, which are part of New York city, and Hollywood, which is part of Los Angeles, California, are coded U4.

U5:Dropped. Only one placethe CDP of Arlington, Virginiawas in this subclass in FIPS PUB 95-2; it has been recoded as U1 as a place and as Z3 as a subclass in FIPS 55-3 as a county subdivision.

U6:Identifies a populated place located wholly or substantially outside the boundaries of any incorpo rated place or CDP with an authoritative common name recognized by the U.S. Geological Survey.

U8:Identifies a populated place located wholly or substantially outside the boundaries of an incor- porated place or CDP but whose name has not been verified as authoritative by the U.S. Geological Survey.

U9:Identifies a CDP that is coincident with or approximates the area of an Alaska Native Village statistical area. The Other Name Code references the Alaska Native Village statistical area; see subclass E2. This subclass is new for FIPS 55-3.

D1:Identifies a federally recognized American Indian reservation and its associated trust land that does not also serve as a primary county division.

D2:Identifies a federally recognized American Indian reservation that exists in a single county and also serves as a primary county division (applies only in Maine and New York). This subclass is new for FIPS 55-3.

D3:Identifies a federally recognized American Indian tribal government that holds off-reservation property in trusttrust landfor a tribe or individual member(s) of a tribe, and the trust land is not associated with a specific American Indian reservation. This subclass is new for FIPS 55-3.

D4:Identifies a State-recognized American Indian reservation that does not also serve as a primary county division.

D5:Identifies a State-recognized American Indian reservation that exists in a single county and also serves as a primary county division (applies only to New York).

D6:Identifies a statistical entity delineated for the Census Bureau to delimit an area containing the American Indian population over which a federally or State-recognized American Indian tribe not having a recognized reservation has jurisdiction (tribal jurisdiction statistical areaTJSAin Oklahoma) and/or provides benefits and services to its members (tribal designated statistical areaTDSAin other States). This subclass is new for FIPS 55-3.

D7:Identifies an administrative division of an American Indian tribal government. For example, the chapters of the Navajo Nation. This subclass is new for FIPS 55-3.

D8:Identifies an alternate authoritative common name of any member of the other subclasses of Class D. The place code of the legal name is referenced in the ``Other Name Code'' of the record, and in the entry for the legal name, the ``Other Name Code'' references the alternate. This subclass is new for FIPS 55-3.

D9:Dropped as a subclass in FIPS 55-3. The entity represented by this subclassthe Oklahoma Historic Reservation Area, which was allocated to 63 countieshas been deleted and replaced by the TJSAs identified as part of subclass D6.

Alaska Native Villages (ANVs) are legal entities that may not have legally established boundaries. The Census Bureau, in cooperation with Alaska Native officials, has delineated boundaries that identify the settled portion of most Alaska Native Village tribal communities them from the legal entities they represent, these statistical entities are referred to as Alaska Native Village statistical areas (ANVSAs). The FIPS entity code scheme assigns a single code to represnet both the legal ANV and ANVSA which designations appear in parentheses after the legal entity name. Alaska Native Regional Corporations (ANRCs) are legal entities with boundaries determined in the Alaska Native Claims Settlement Act to conduct the business and nonprofit affairs of Alaska Natives and their communities.

E1:Identifies an ANV/ANVSA where the ANVSA boundaries do not coincide with or approximate an incorporated place or a CDP.

E2:Identifies an ANV/ANVSA where the ANVSA boundaries coincide with or approximate a CDP. The Other Name Code identifies the CDP; see subclass U9.

E6:Identifies an ANV/ANVSA where the ANVSA boundaries coincide with or approximate an incorpo rated place. The Other Name Code identifies the incorporated place; see subclass C6.

E7:Identifies an ANRC, an area established by the Alaska Native Claims Settlement Act; twelve ANRCs cover all of the State of Alaska except the Annette Islands Reserve, an American Indian reserva tiona thirteenth ANRC is for Alaska Natives residing outside of Alaska and this ANRC is not included in FIPS 55. This subclass is new for FIPS 55-3.

Class H:Counties and County Equivalents

Class H includes all the primary divisions of a state or state equivalent usually called counties, but also includes borough and census areas in Alaska, parishes in louisiana, municipios in Puerto Rico, and districts, islands, and municipalities in the Outlying Areas. The class does not include independent cities which are classified as class C7.

H1:Identifies an active county or county equivalent that does not qualify under subclass C7 or H6.

H4:Identifies an inactive or nonfunctioning county or county equivalent that does not qualify under subclass H6.

H5:Dropped as a subclass in FIPS 55-3 . The 17 entities recorded in this subclass in FIPS 55-2, which identified inactive or nonfunctioning counties or county equivalents coextensive with a single primary county division, have been reassigned to code subclass H4 or H6, as appropriate.

H6:Identifies a county or county equivalent that is areally coextensive or governmentally consolidated with an incorporated place, part of an incorporated place (applies only to New York City), or a consolidated city (see subclass C3). The Other Name Code of the record references the name of the incorporated place or consolidated city. (The incorporated place serves as the active governmental unit.)

T1:Identifies an active minor civil division (MCD) that is not coextensive with an incorporated place.

T2:Dropped as a subclass in FIPS 55-3. The entities in this subclass in FIPS 55-2, which identified active MCDs coextensive with a census designated place (CDP), have been assigned to subclass T1.

T3:Dropped as a subclass in FIPS 55-3. The entities in this subclass in FIPS 55-2, which identified active MCDs not coextensive with a CDP or incorporated place but including a populated place of the same name, have been assigned to subclass T1.

T5:Identifies an active MCD that is coextensive with an incorporated place. (The incorporated place usually has the same name as the MCD, and usually the officials of the incorporated place administer the governmental functions of the MCD.)

Z1:Identifies an inactive or nonfunctioning minor civil division (MCD) recognized as a primary county division by the Census Bureau, such as the townships in Arkansas and North Carolina and the magisterial districts in Virginia and West Virginia.

Z2:Dropped as a subclass in FIPS 55-3. The 27 entities recorded in this subclass in FIPS 55-2, which identified unorganized territories (unorgs.) that were coextensive with a single disorganized MCD or member of subclass Z4, have been assigned to subclass Z3.

Z3:Identifies a unorg. established as an MCD equivalent by the Census Bureau. Some unorgs. may be coextensive with one or more disorganized MCDs and/or members of subclass Z4, or may include (but not be coextensive with) one or more such members. Subclass Z3 also identifies a primary county division that duplicates the county entry (applies only to Arlington County, Virginia).

Z4:Identifies a nonfunctioning or disorganized township or similar entity not recognized as an MCD by the Census Bureau; must be either coextensive with or included in an unorg., such as the survey townships in Maine (numbered in the 90000 series). If coextensive, the Other Name Code identifies a member of subclass Z3; if included, the Part of Code identifies a member of subclass Z3.

Z5:Identifies a census county division (in 21 States), census subarea (Alaska), or census subdistrict (Virgin Islands of the United States).

Z6:Identifies a sub-MCD in Puerto Rico (subbarrio) and the Federated States of Micronesia (a munic ipal district). This subclass is new for FIPS 55-3.

Z7:Identifies an independent incorporated place that serves as a primary county division in Iowa, North Carolina, and in counties containing only nonfunctioning MCDs in Nebraska.
