Founded in 1946, the Surveys of Consumers (SCA) promotes the importance of consumer spending and saving decisions in determining the course of the national economy. Each month, the survey interviews a minimum of 800 people to collect samples representative of all American households. SCA is proven to be an accurate indicator of the national economy’s future course.

Founded in 1968, the Panel Study of Income Dynamics PSID is the world’s longest-running household panel survey. It has made way for the study of dynamism in social and behavioral processes, resulting in over 4,000 peer-reviewed publications. The National Science Foundation, the study’s lead sponsor, named PSID as one of its 60 most significant innovations.
