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.


This variable is comparable across available years.

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.


  • Civilians 15+ currently employed as wage/salary workers and in 2 (out of 8) rotation groups and is paid annually. Excludes self-employed persons.
