The computerized questionnaire for just the labor force portion of a CPS interview consists of more than 200 questions. However, complex skip patterns using the responses to several questions insure respondents are asked only a very small set of questions about themselves. Averaged over the 8 months of interviews, the labor force portion of the CPS interview lasts about 6 minutes per person. Obviously, larger households and households containing someone who has multiple jobs or started a new job take longer. Single-person households or households containing only retired persons who do not wish to work take less time.
For supplement data that has already been released, you can find complete questionnaires in each supplement's technical documentation.
