For example, research on the predictors and consequences of family transitions will be transformed by IPUMS CPS. Linked CPS data open up new research opportunities for analysis over time. Surveys are often incompatible across years, and even when questions and variables do not change, researchers are hesitant to work with multiple files and codebooks.Д¬PSIDP means that researchers will no longer face these barriers to longitudinal analyses. Third, there is a data integration barrier for researchers. Second, navigating the maze of CPS documentation-even to determine the feasibility of a CPS-based longitudinal study-is daunting for researchers. Changes in the composition of the household due to migration and mortality (along with non-response and data recording errors) further complicate linking.

For several years of CPS data, the serial numbers (which constitute the most obvious basis for record linkage) are not unique across households. The 4-8-4 design the CPS survey-where households are in the survey for four months, out for eight, and back in the survey for four-limits the portion of the sample that could be linked in adjacent months and in consecutive years. First, linking records across data files without CPSIDP is technically difficult for several reasons.

With the addition of the new variable, IPUMS-CPS addresses the three main barriers to making full use of the CPS data as a longitudinal resource. The MPC dramatically expanded the IPUMS CPS data series to encompass over 500 U.S. Over the past five years, IPUMS CPS has been the fastest growing component of the IPUMS. The recent growth of the IPUMS CPS database has coincided with an explosion in use, by both old and new users. IPUMS CPS has been delivered by IPUMS for over a decade. It is also one of the most widely used data resources in social and economic research due to the breadth of topics covered in the survey including, employment, poverty, health insurance, food security, and voting. The Current Population Survey is the primary source of data for information about labor force participation in the United States.

The identifier, the result of a major initiative from the Minnesota Population Center, uniquely identifies individuals who are in the CPS and is assigned to the individual in each of the (up to) eight times over sixteen months that the individual is in the survey. IPUMS CPS has added a new variable to unlock longitudinal information in CPS data called CPSIDP.
