For a list of metropolitan areas identified and the corresponding codes, consult the links below for the appropriate time period. Note that some metropolitan areas are not available in all months of a time period.
99998 = Unidentified or nonmetropolitan
99999 = Missing data
METFIPS gives the original (unrecoded) codes for the respondent's metropolitan area of residence. For the same variable recoded to FIPS codes from the 1990 census, see (METAREA) (definitions of metropolitan areas can change over time, however). METFIPS information was added to the ASEC CPS data by the Census Bureau, not collected from respondents.
Not all metropolitan areas are identified: see under "Codes" for more information. Note also that some component counties are not included in the CPS sample of households in certain metropolitan areas. See the "Specific Metropolitan Identifiers" Appendix of the appropriate month's technical documentation for more information on whether a specific metropolitan area sample has excluded components. For more information on the definitions and components of metropolitan areas over time, see the Census Bureau website; for the current metropolitan area definitions, see here.
Note that the Census Bureau warns: "One set of estimates that can be produced from CPS microdata files should be treated with caution. These are estimates for individual metropolitan areas. Although estimates for the larger areas such as New York, Los Angeles, and so forth, should be fairly accurate and valid for a multitude of uses, estimates for the smaller metropolitan areas (those with populations under 500,000) should be used with caution because of the relatively large sampling variability associated with these estimates."
Definitions of metropolitan areas as well as codes change over time. Prior to 1977, the code scheme used is CPS-specific. After 1977, the code scheme is the metropolitan area's FIPS code. Starting May 2004, New England metropolitan areas are defined using New England City and Town Area (NECTA) definitions. The codes for these areas correspond to NECTA codes, not to the metropolitan area (CBSA) FIPS code. See under the "Codes" tab for more details on the specific codes over time.
