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.

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.
