INDLY is a 3-digit numeric variable. Codes are the same as those for IND.
(Codes for 1963-1967 are 2 digits; each is preceded by a zero in the first position).



INDLY reports the industry in which the respondent worked during the previous calendar year. A respondent who held more than one job during the preceding year was to report the job that lasted longest. The reference period for INDLY, the preceding calendar year, is the same as the reference period for income variables in IPUMS-CPS.

The CPS interviewer collected information by asking what kind of work the person was doing last year, and Census Bureau staff coded the information into the CPS or census industrial classification. Researchers who wish to work with a consistent occupational coding scheme for 1968-2002 should use the IND50LY variable.

The industry of persons employed at the time of the survey is reported in IND. IND also provides information about the most recent job for persons not in the labor force at the time of the survey. For general discussion of employment concepts, including the definition of those not in the labor force, see the documentation on EMPSTAT.

The 1962 sample is unavailable due to a shared code (0) between 'agriculture' and 'not in universe'. However, the unharmonized variable (INDLYR) is provided for users who wish to analyze the data independently.


In addition to universe changes, INDLY changed due to shifts in the industrial coding scheme. For 1963-1967, an industrial classification scheme with fewer than 50 codes was used. In 1968-1970, industries were coded using the 1960 census classification scheme; in 1971-1982, using the 1970 census classification scheme; in 1983-1991, using the 1980 census classification scheme; in 1992-2002, using the 1990 census classification scheme; and for 2003 forward, using the 2000 census classification scheme. INDLY provides the codes given in the original CPS data; IND50LY, which recodes industries into a common format using the 1950 census classification scheme, provides comparability over time beginning in 1968.


  • 1963-1967: Civilians age 14+ coded as "match" on the FEBMAR variable and who worked last year (pre-1968 samples do not include persons under age 14).
  • 1968-1979: Civilians age 14+ who worked last year.
  • 1980-1987: Persons age 15+ who worked last year and were not in the armed forces last year.
  • 1988+: Persons age 15+ who worked last year.
