Housed at ICPSR at the University of Michigan, this public repository makes available hundreds of datasets, mainly U.S.-based for free downloading. Examples of subject categories are Community Studies, Crime and Delinquency, Police, and Victimatization studies. A selection of PHDCN data collections is available for online data analysis via the Survey Documentation and Analysis program developed and maintained by the Computer-Assisted Survey Methods Program at the University of California, Berkeley.
