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.
