Conducted to fulfill budgetary requirements for the 2015 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.' The Parallel Survey, which was fielded in March and April 2015, used the same traditional health insurance and income questions that were used in the 2013 CPS ASEC and previous years. Efforts were made to ensure that the Parallel survey resembled the traditional CPS ASEC, including using the same interviewers, a production setting, and the full CPS basic interview that precedes the March supplement questions. In addition, the Parallel survey was processed by the same system that processes the CPS ASEC.
