About ICPSR:

The Inter-university Consortium for Political and Social Research (ICPSR),established in 1962, is an integral part of the infrastructure of social science research. ICPSR maintains and provides access to a vast archive of social science data for research and instruction, and offers training in quantitative methods to facilitate effective data use. To ensure that data resources are available to future generations of scholars, ICPSR preserves data, migrating them to new storage media as changes in technology warrant. In addition, ICPSR provides user support to assist researchers in identifying relevant data for analysis and in conducting their research projects.

Data Collection Notes:

(1) The data files are provided as SPSS export files and as SAS transport files that were created using the SAS XPORT engine.
(2) MIDUS is the main research activity of the John D.and Catherine T. MacArthur Foundation Network on Successful Midlife Development (MIDMAC). Additional information on MIDMAC research projects is provided on the MIDMAC Web site at http://midmac.med.harvard.edu.(link)
(3) This collection has not been processed by ICPSR staff. ICPSR is distributing the data and documentation for this collection in essentially the same form in which they were received. When appropriate, hardcopy documentation has been converted to machine-readable form and variables have been recoded to ensure respondents' anonymity.
(4) The codebooks and data collection instruments are provided by ICPSR as Portable Document Format(PDF)files. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided on the ICPSR Web site.

Mission Statement:

The Inter-university Consortium for Political and Social Research is an organization of member institutions working together to:

ICPSR encourages and facilitates research and instruction in the social sciences and related areas by acquiring, developing, archiving, and disseminating data and documentation relevant to a wide spectrum of disciplines, and by conducting related instructional programs.
