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.

The James M. and Cathleen D. Stone Center for Inequality Dynamics (CID) was founded at the University of Michigan Institute for Social Research in 2019. The mission of CID is to: produce cutting-edge research on social inequality, especially wealth inequality, train the next generation of inequality scholars, and build data infrastructure and increase data accessibility.
