Introducing CPS-ASEC Longitudinal Extracts

The panel component of the Current Population Survey and new Longitudinal Extracts

Did you know that the Current Population Survey (CPS) – an important source of information on unemployment, poverty, and many other topics – has a panel component? If you didn’t, you’re not alone. The CPS rotation pattern is complex and can be difficult to work with. In fact, IPUMS CPS has held multi-day workshops intended to introduce researchers to the CPS panel component, help them understand the rotation pattern, and show some convenient IPUMS CPS features that make working with CPS panel data a little easier. If you’re completely new to the CPS panel, check out the materials from our latest workshop!

Maybe you did know about the CPS panel component, but looked at the complex rotation pattern, the Census Bureau guidelines and linking keys, and decided that this was for the birds. If this sounds like you, then our newest IPUMS CPS feature may be right for you! IPUMS CPS users can now download CPS-ASEC panels that contain two observations per person across a one-year period as longitudinal extracts. The rest of this blog post will explain what you are getting when you make a CPS-ASEC longitudinal extract and will walk you through how to create one for yourself.

IPUMS Announces 2020 Research Award Recipients

September 29, 2021May 17, 2021 by mpcblog

IPUMS is excited to announce the winners of its annual IPUMS Research Awards. These awards honor the best-published research and nominated graduate student papers from 2020 that used IPUMS data to advance or deepen our understanding of social and demographic processes.

IPUMS, developed by and housed at the University of Minnesota, is the world’s largest individual-level population database, providing harmonized data on people in the U.S. and around the world to researchers at no cost.

There are six award categories, and each is tied to the following IPUMS projects:

IPUMS USA, providing data from the U.S. decennial censuses, the American Community Survey, and IPUMS CPS from 1850 to the present.
IPUMS International, providing harmonized data contributed by more than 100 international statistical office partners; it currently includes information on 500 million people in more than 200 censuses from around the world, from 1960 forward.
IPUMS Health Surveys, which makes available the U.S. National Health Interview Survey (NHIS) and the Medical Expenditure Panel Survey (MEPS).
IPUMS Spatial, covering IPUMS NHGIS and IPUMS Terra. NHGIS includes GIS boundary files from 1790 to the present; Terra provides data on population and the environment from 1960 to the present.
IPUMS Global Health: providing harmonized data from the Demographic and Health Surveys and the Performance Monitoring and Accountability surveys, for low and middle-income countries from the 1980s to the present.
IPUMS Time Use, providing time diary data from the U.S. and around the world from 1965 to the present.

Over 2,500 publications based on IPUMS data appeared in journals, magazines, and newspapers worldwide last year. From these publications and from nominated graduate student papers, the award committees selected the 2020 honorees.

How has COVID-19 affected 2020 data collection efforts?

IPUMS integrates data from several major US surveys that collect data throughout the year. Below, we discuss how COVID-19 has affected how US statistical agencies have collected these survey data in 2020.

Current Population Survey (CPS)

The Bureau of Labor Statistics (BLS) and the Census Bureau have continued to collect data on a monthly basis during the COVID-19 pandemic, implementing some procedural modifications to protect the safety of respondents and Census Bureau employees and adding a short supplement to capture the effects of the pandemic on work in the United States.

Changes to Interviewing Procedures

Current Population Survey (CPS) data collection for March had already begun when the Census Bureau suspended in-person data collection on March 20th, 2020. Two call centers that assist with CPS data collection also closed down at this time. However, data collection continued exclusively by phone through June of 2020. In July, in-person interviews began in some areas of the country and the call centers that had been closed in March re-opened. In-person interviews were resumed in all areas of the country in September 2020 and data collection has returned to a normal routine. More information on how alternative data collection procedures affected response rates, attrition, and employment data is available on the IPUMS CPS website.

Additional COVID-related content

The COVID-19 outbreak prompted the BLS to add five questions to the monthly CPS survey about work in the time of COVID-19. These questions were first asked in May. Though the question about foregoing medical care due to the pandemic was dropped from the survey after October of 2020, all other questions will remain in the survey until further notice. Researchers may preview the questions or access the COVID-specific variables via IPUMS CPS.

IPUMS CPS will continue to update our documentation on the effects of the pandemic on CPS data collection and to make new data available as quickly as possible. Follow @ipums on Twitter for the latest updates.

IPUMS has updated the family interrelationship variables in IPUMS CPS and the Integrated Health Interview Series (IHIS) to include same-sex and cohabiting couples. The updated variables dramatically reduce research barriers for those interested in this family and household context.

IPUMS CPS has added a new variable to unlock longitudinal information in CPS data called CPSIDP. 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.
