Most of the ICPSR datasets are downloadable only by current members, including Vassar College. Federally funded data are freely available to the general public.
For most datasets, ICPSR makes files available in ASCII, SPSS, SAS, and Stata file formats or provides the setup files for the statistical software packages. In some cases only the ASCII format is available.
Steps for downloading data:
ICPSR/ DSDR restricts the access and use of datasets containing information that might compromise the anonymity or privacy of individuals, or if the dataset contains particularly sensitive confidential information about the participants, Any dataset that includes information regarding populations at higher risk of deductive disclosure (such as children, adolescents, prisoners, and parents) is especially likely to be released as restricted-use.
Users must complete an agreement and apply for the public use version of the data. See Accessing Restricted Data at ICPSR for complete details.
