This collection of datasets addresses social science issues and is housed at the University of Wisconsin. Free registration is required to access the datasets.

These datasets come from the book "STAT LABS: Mathematical Statistics Through Applications." Below the link for each dataset are descriptions of the variables for that dataset. Datasets are in text format and address topics such as maternal smoking and infant health, video games, radon, cytomegalovirus DNA, HIV, crab molting, voting, snow gauge calibration, down syndrome, and tape drive quality.
