Chapter 11. Current Population Survey Supplemental Inquiries INTRODUCTION In addition to providing data on the labor force status of the population, the Current Population Survey (CPS) is used to collect data for a variety of studies on the entire U.S. population and specific population subsets. These studies keep the nation informed of the economic and social well-being of its people and are used by federal and state agencies, private foundations, and other organizations. Supplemental inquiries take advantage of several special features of the CPS: large sample size and general purpose design; highly skilled, experienced interviewing and field staff; and generalized processing systems that can easily accommodate the inclusion of additional questions. Some CPS supplemental inquiries are conducted annually, others every other year, and still others on a one-time basis. The frequency and recurrence of a supplement depend on what best meets the needs of the supplement’s sponsor. In addition, any supplemental inquiry must meet strict criteria discussed in the next section. Producing supplemental data from the CPS involves more than just including additional questions. Separate data processing is required to edit responses for consistency and to impute missing values. An additional weighting method is often necessary because the supplement targets a different universe from that of the basic CPS. A supplement can also engender a different level of response or cooperation from respondents. CRITERIA FOR SUPPLEMENTAL INQUIRIES A number of criteria to determine the acceptability of undertaking supplements for federal agencies or other sponsors have been developed and refined over the years by the U.S. Census Bureau, in consultation with the U.S. Bureau of Labor Statistics (BLS). The staff of the Census Bureau, working with the sponsoring agency, develops the survey design, including the methodology, questionnaires, pretesting options, interviewer instructions and processing requirements. The Census Bureau provides a written description of the statistical properties associated with each supplement. The same standards of quality that apply to the basic CPS apply to the supplements. The following criteria are considered before undertaking a supplement: Current Population Survey TP66 U.S. Bureau of Labor Statistics and U.S. Census Bureau 1. The subject matter of the inquiry must be in the public interest. 2. The inquiry must not have an adverse effect on the CPS or other Census Bureau programs. The questions must not cause respondents to question the importance of the survey and result in losses of response or quality. It is essential that the image of the Census Bureau as the objective fact finder for the nation is not damaged. Other important functions of the Census Bureau, such as the decennial censuses or the economic censuses, must not be affected in terms of quality or response rates or in congressional acceptance and approval of these programs. 3. The subject matter must be compatible with the basic CPS survey and not introduce a concept that could affect the accuracy of responses to the basic CPS information. For example, a series of questions incorporating a revised labor force concept that could inadvertently affect responses to the standard labor force items would not be allowed. 4. The inquiry must not slow down the work of the basic survey or impose a response burden that may affect future participation in the basic CPS. In general, the supplemental inquiry must not add more than 10 minutes of interview time per respondent or 25 minutes per household. Competing requirements for the use of Census Bureau staff or facilities that arise in dealing with a supplemental inquiry are resolved by giving the basic CPS first priority. The Census Bureau will not jeopardize the schedule for completing the CPS or other Census Bureau work to favor completing a supplemental inquiry within a specified time frame. 5. The subject matter must not be sensitive. This criterion is imprecise, and its interpretation has changed over time. For example, the subject of birth expectations, once considered sensitive, has been included as a CPS supplemental inquiry. 6. It must be possible to meet the objectives of the inquiry through the survey method. That is, it must be possible to translate the supplemental survey’s objectives into meaningful questions, and the respondent must be able to supply the information required to answer the questions. 7. If the supplemental information is to be collected during the CPS interview, the inquiry must be suitable for the personal visit/telephone procedures used in the CPS.
