The Census Bureau conducts three major surveys to collect income and government program participation data. These include the Survey of Income Program Participation (SIPP), the Current Population Survey (CPS) Annual Demographic Survey (also known as the CPS March Supplement), and the Survey of Program Dynamics (SPD). Each of these surveys collects data on earnings, a full range of income sources, and government program participation. In addition to these surveys, the Census Bureau is conducting an experimental survey, referred to as the SIPP Methods Panel, to test new questions for the core SIPP interview.
