Founded 2011

Social Science Genetic Association Consortium

The SSGAC is a cooperative enterprise among medical researchers and social scientists that coordinates genetic association studies for social science outcomes and provides a platform for interdisciplinary collaboration and cross-fertilization of ideas. The SSGAC also promotes the collection of harmonized and well-measured phenotypes.

The consortium in numbers

29 publications
47 phenotypes in the PGI Repository
11 datasets in the PGI Repository
100+ contributing cohorts

Figures as of July 2026.

Current initiatives

Within-family GWAS of multiple phenotypes
Ongoing updates of the Polygenic Index Repository
Developing methods for multi-ancestry genetic analysis
Developing methods to estimate assortative mating
