In 2016, the Census Bureau fielded a Split-Panel test of the Current Population Survey Annual Social and Economic Supplement (CPS ASEC) to fulfill budgetary requirements for the 2016 fiscal year. According to Public Law 113-235 Dec. 16, 2014, the Census Bureau was to "collect data for the Annual Social and Economic Supplement to the Current Population Survey using the same health insurance questions included in previous years, in addition to the revised questions implemented in the Current Population Survey beginning in February 2014."

There were 99,000 addresses in the 2016 CPS ASEC sample; a sub­sample of 5,000 addresses were randomly assigned to be eligible to receive the traditional health insurance questions (i.e., pre-2014 CPS ASEC questions).  The remaining sample (94,000 addresses) were eligible to receive the set of the redesigned health insurance questions.

According to the 2016 CPS ASEC Split-Panel Test, the uninsured rate of 9.6 percent from the traditional health insurance questions was not statistically different from the uninsured rate of 9.1 percent from the redesigned questions.
