Weeks worked per year, outgoing rotation groups


WKSWORKORG is a 2-digit numeric value.

0 = NIU (Not In Universe)
98 = Don't Know


WKSWORKORG reports the number of weeks, in single weeks, that the respondent usually works per year. WKSWORKORG is one of the earner study questions, which is also known as the outgoing rotation group questions. Private wage or salaried workers are asked the periodicity for which they are paid. Workers who are paid annually, excluding those who are self-employed, are asked how many weeks a year they are paid for. Researchers should use the EARNWT weight with this variable.

WKSWORKORG differs from WKSWORK1 in that the period of reference for WKSWORK1 is the preceding year, whereas WKSWORKORG corresponds to the respondent's current usual weeks worked per year.

WKSWORKORG is one of the Outgoing Rotation/Earner Study questions.


According to Technical Paper 66, issued jointly by the Census Bureau and the Bureau of Labor Statistics, individuals eligible for the earner study are civilians age 15 and older in rotation groups 4 or 8 who are not self-employed.  In any given month, approximately 1/4 of the CPS sample is in the earner study and each household should appear in the earner study exactly twice. Based on documentation from Unicon and NBER, and after an inspection of the original CPS data, we recommend that users impose the CPS eligibility restrictions in any analyses of earner study variables.

IPUMS CPS has been unable to produce a completely accurate universe statement for WKSWORKORG. The given universe is the best empirically investigated universe found. In each month there are a substantial number of respondents (generally around 500, but as high as 700 in some months) that meet known universe criteria yet have no responses to WKSWORKORG. There are also a small number of respondents (generally around 30 per month) who do not meet universe requirements and have responses to WKSWORKORG.

This variable is otherwise comparable across available years.


  • Employed civilians 15+ in outgoing rotation groups that were paid annually. Excludes self-employed persons.
