Current Population Survey (CPS) Data at the NBER
Current Population Survey (CPS) Data at the NBER
The CPS is the U.S. Government's monthly survey of unemployment and labor force
participation. The BLS maintains a
CPS Home Page with a great deal of information about the survey and access
to downloads of recent data.
The NBER maintains an extensive collection of
historical CPS public use tapes for its research staff. Except for the MORG
file which is sold as a CD-ROM all of the data is available for download.
Five Categories:
- Basic Monthly Data are the primary
source of labor force statisitcs in the U.S. Topics include
employment, earnings, and demographic data. CPS Supplements, when collected,
are not a part of the Basic Monthly Data files. Households are in the survey
eight times: four consecutive months, eight months off, and then a final
four months. Available for every month from 1976 on.
SAS, SPSS, & Stata data definition statement files
- CPS Supplements,
have the same data as the
Basic Monthly Files sometimes in a different order, plus supplemental information on topics such
as schooling, fertility, immigration, and income. We have many of these files from
1964 to present in the original BLS formats.
SAS, SPSS, & Stata data definition statement files
- Merged Outgoing Rotation Groups (MORG)
are extracts of the Basic Monthly Data during the household's fourth and eighth
month in the survey, when usual weekly hours/earnings are asked.
Documentation Files are also available.
- Mare-Winship Files are (nearly) uniform
subsets of 168 variables from March Annual Demographic Supplement files.
These cover 1964-1992.
- CPS May Extracts are (relatively) standardized extracts
of 200 variables made from the CPS May Supplement. These are available for 1967 to 1987; 1978 was
the last year in which usual weekly hours/earnings were asked only in May.

Changes in Metropolitan Areas, 1950-1994
lists each metropolitan area in the CPS, the counties that comprise the MAs, and the changes in
the MA's county composition over time.
1990 Land Area for Metropolitan Areas (1998 Definition) lists the
changes in the MAs (a handful have been added, or added to) since the publication of
the chapter above.
