Reading Current Population Survey (CPS) Basic Monthly Data 2000-2002 Extract Files with SAS, SPSS, or Stata
The CPS adopted the 2002 Census Bureau industry and occupation classification systems, which are derived from the 2002 North American Industry Classification System and the 2000 Standard Occupation Classification System. These new classification systems create breaks in the time series for occupational and industry data at all levels of aggregation.In addition, the Census 2000-based weights were implemented beginning in January 2003. ( The CPS March 2002 supplement and the March 2001 SCHIP files used Census 2000-based weights as well ) .
For comparison over time, the BLS released the 2000-2002 Current Population Survey Extract files.
The Extract files contain revised class of worker, industry, occupation, union, and
Census 2000-based weight variables.
The BLS also produced many tables comparing the distribution of the 1990 and 2002 industry and occupation codes.
The SAS, SPSS, and Stata files were created by email@example.com at the NBER to make access to the BLS/Census Current Population Survey Extract files a bit more straightforward and easy. The monthly files can be matched to the original CPS Basic Monthly data files using QSTNUM, HRMONTH, HRYEAR4, and OCCURNUM.
