The ICPSR Internet Gopher Server provides services and data from the Inter-university Consortium for Political and Social Research (ICPSR). This data includes the 1990 US census, the VARIABLES database, which provides information from many ICPSR surveys, and data archives such as the National Archive of Computerized Data on Aging. Most of the information is searchable by keywords or by WAIS. ICPSR is a non-profit group which acts as a central repository for data of interest to social scientists.
