Codes and Frequencies
WKSWORK2, like WKSWORK1, reports the number of weeks that the respondent worked for profit, pay, or as an unpaid family worker during the preceding calendar year. It differs from WKSWORK1 in that responses are given in intervals: 1-13 weeks; 14-26 weeks; 27-39 weeks; 40-47 weeks; 48-49 weeks; and 50-52 weeks. Respondents were prompted to include weeks in which they worked for even a few hours and to include paid vacation and sick leave as work.
Apart from changes in the universe, WKSWORK2 is comparable over time.
Comparability with IPUMS-USA
The lower age limit for WKSWORK2 differs for IPUMS-USA and IPUMS-CPS. The 1980, 1990, and 2000 censuses and the ACS collected employment information on persons 16 and older, while the CPS used an age limit of 14 and older for 1976 to 1979 and 15 and older beginning in 1980. Because the CPS is designed to measure the labor force experience of civilians, members of the armed forces were not asked this question in the survey. Persons in the military are included in the census and ACS data. Until the 1980 census, census data on weeks worked during the previous year were available only in the form of intervals. Fortunately, the same intervals are used in IPUMS-USA and IPUMS-CPS, so researchers wishing to combine data from several decades and the two sources can use the compatible WKSWORK2 variable.
- 1962-1967: 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.
- 1980-1989: Civilians age 15+ who worked last year.
- 1990-2018: Persons age 15+ who worked last year.
