Expert Meeting on Changes to the Current Population Survey Annual Social and Economic Supplement (CPS ASEC)
SHADAC researcher Brett Fried served as a discussant at the Expert Meeting on Changes to the CPS ASEC, held in Suitland, Maryland on May 13, 2019. The U.S. Census Bureau convened this meeting to discuss the implications of the new data processing system implemented in the 2017 CPS ASEC Research File and gather feedback from key stakeholders.
The new processing system addresses changes made to the income and health insurance questions in the 2014 CPS ASEC and changes in the 2015 CPS ASEC that allow spouses and unmarried partners to identify as opposite- or same-sex.1,2,3 Further details on the new system and differences in health insurance estimates between the 2017 Research File and the 2017 Production File were recently published in a series of working papers by the Census.
For the May Expert meeting, Brett provided commentary on the health insurance portion of the Census presentations, placing the findings into the context of historical work performed by SHADAC in evaluating health insurance estimates in the CPS ASEC.
The invitation by the Census Bureau to present at this meeting continues a long tradition of partnering with SHADAC and other outside researchers to evaluate the impacts of changes to CPS processing systems and survey questions. Examples of SHADAC’s contribution to this work include a 2011 paper examining modifications of the imputation routine in the CPS ASEC4 and SHADAC’s current work with Census on measurement error in health insurance coverage in the CPS ASEC and the ACS.5,6 SHADAC is also currently working on two briefs that will address differences at the state level, and those will be available in late summer or early fall.
2019 American Community Survey (ACS) Data Users Conference
Among the many other presentations at the conference, three generated particularly high levels of interest. Census researcher Rolando Rodríguez presented on the Census Bureau’s new approach to data privacy, highlighting the concern that current ACS disclosure avoidance practices are not adequate and that more formal privacy methods, informed by those used for the 2020 Decennial census, will be needed.8 This could have potential implications for comparability of estimates across years, availability of public use files, and availability of estimates for small areas.
Census researcher Zach Whitman discussed the Census Bureau’s new data dissemination platform, data.census.gov, noting that no new data will be included in the American FactFinder as of June 2019 and legacy American FactFinder data will be transitioned to the new platform by June 2020.9 Users are encouraged to use the tool and provide feedback to the Census Bureau.
Constance Citro from the National Academies of Sciences provided commentary on the two presentations, noting that both were “excellent and thought provoking” talks. However, she was concerned that it was not enough to just invite input from users, but rather “two-way user interaction” is needed instead. She then outlined steps that the Census Bureau could take to “ensure that new privacy protection techniques and the new platform are implemented with full consideration of alternatives and user needs.”10
Finally, individuals from the Census Bureau responded in a plenary session to concerns about the potential impact of including a citizenship question on the 2020 Decennial Census by discussing an analysis they were conducting to estimate the effect on response rates. This paper, “Predicting the Effect of Adding a Citizenship Question,” is now available. The authors estimate that adding a citizenship question would result in an 8 percentage point drop in the response rate for households that have at least one non-citizen as compared to households with only citizens.11
