Social Science Data

A good place to start is the Hesburgh Libraries Datasets & Statistics Collection, which offers a comprehensive list of datasets and statistics organized by subject, location and source. 

An alternative is the Inter-university Consortium for Political and Social Research (ICPSR). The ICPSR maintains one of the world’s oldest and largest digital data archives in the social sciences. It hosts specialized collections of data in education, aging, criminal justice, substance abuse and terrorism, among many other fields. The University of Notre Dame is a member institution of the ICPSR and thus everyone affiliated with Notre Dame receives full access to the data archive.

Another alternative is the Dataverse Network, and in particular the Harvard Dataverse Network, which is open to all scientific data from all disciplines worldwide and it includes one of the world's largest collection of social science research data.

There are many other data archives and repositories, some of which are specific to certain research communities. Databib and re3data contain a large searchable collection of online research data repositories.
