ICPSR (The Inter-University Consortium for Political and Social Research) is a repository of social science data that has been shared by researchers. It includes opinion polls, longitudinal studies, census data, social data and much more.
ICPSR is free to search but you must log in to download data.
Create a MyData account to access all datasets that are part of our membership. Once you create an account, you can access ICPSR from anywhere, but you will need to log in from campus or through the proxy server every six months to re-establish your affiliation.
Some data are free for the public to download, but you must still log in, either with a MyData account or with a social media account.
Staff at ICPSR recommend using this link only for establishing accounts. The proxy server can cause issues when downloading datasets and doing online analysis.
To prevent ICPSR access problems during the COVID-19 pandemic, users must revalidate their accounts. This requires logging in with a University of Chicago IP address. To do this, use the cVPN to connect to the University's IP range and then log into ICPSR.
Most data in ICPSR requires statistical software for analysis. Some data can be analyzed using online tools, but these are limited.
Data are available in many different file formats. Recent data are formatted for SAS, SPSS and Stata and all data are available in ASCII plain text.
