Note: The Census 2000 occupational classification has 509 categories. Of these 369 exactly match SOC detailed categories; another 127 match the SOC at its broad category or minor group level. There are 13 aggregates of multiple SOC categories that do not have an exact match to a single SOC code. Since each of the 13 aggregates contains more than one SOC equivalent, the Census Bureau will us an "X" or "XX" designation in tabulations that show data for these aggregates. These aggregates are as follows: Census Code and Title: SOC Designation and Title: SOC Code: 073 - Other Business 13-11XX -Miscellaneous Business Operations 13-1061 Operations Specialists Specialists including Emergency Management 13-1199 Specialist 100 - Computer 15-10XX - Miscellaneous Computer Specialists 15-1011 Scientists and including Computer and Information 15-1051 Systems Analysts Scientists and Computer Systems Analysts 15-1099 196 - Other Life, 19-40XX - Miscellaneous Life, Physical, and 19-4061 Physical, and Social Social Science Technicians including 19-4090 Science Technicians Social Science Research Assistants 255 - Other Education, 25-90XX - Miscellaneous Education, 25-9011 Training, and Library Training, and Library Workers except 25-9021 Workers Teacher Assistants 25-9031 25-9099 365 - Medical Assistants 31-909X - Miscellaneous Healthcare Support 31-9092 and Other Healthcare Workers, except Dental Assistants 31-9093 Support Occupations 31-9094 31-9095 31-9096 31-9099 395 - Lifeguards and 33-909X - Miscellaneous Protective 33-9092 Other Protective Service Workers, except Crossing Guards 33-9099 Service Workers 422 - Janitors and 37-201X - Building Cleaning Workers, 37-2011 Building Cleaners except Maids and Housekeeping Cleaners 37-2019 694 - Other Extraction 47-50XX - Miscellaneous Extraction 47-5051 Workers Workers including Rock Splitters, Quarry 47-5099 710 - Electrical and 49-209X - Electrical and Electronics 49-2094 Electronics Repairers, Repairers, Commercial and Industrial 49-2095 Industrial and Utility Equipment, Powerhouse, Substation, and Relay 733 - Industrial and 49-904X - Industrial Machinery Mechanics 49-9041 Refractory Machinery plus Refractory Materials Repairers, 49-9045 Mechanics Except Brickmasons 762 - Other Installation, 49-909X - Installation, Maintenance, and 49-9093 Maintenance, and Repair Repair Workers, All Other, including 49-9099 Workers Fabric Menders, Except Garment 926 - Subway, Streetcar, 53-40XX - Miscellaneous Rail Transpor- 53-4041 and Other Rail Transpor- tation Workers including Subway and 53-4099 tation Workers Streetcar Operators 942 - Other Transporta- 53-60XX - Miscellaneous Transportation 53-6041 tion Workers Workers including Traffic Technicians 53-6099
