Availability of Data
Some studies listed on the TPDRC Web site are freely available to everyone because organizations such as the U.S. Department of Justice supported their processing; other studies listed under the TPDRC site are available only to those connected with an institution that supports the Inter-university Consortium for Political and Social Research (ICPSR). If you locate a membership-only study that fits your research needs and would like to purchase it, you can find more information about this process on the Nonmember Access to Data page. If you identify several studies or are interested in joining ICPSR, you can find more information about the benefits of membership on the Membership Benefits page.
Variable-Level Searching
This feature searches the variable and value labels across all TPDRC data files that are publicly available. Some TPDRC files have question text included as part of the metadata and, when available, question text is also included in the search.
- Searching is not case sensitive. "Dog" and "dog" return the same results.
- The search engine uses quotation marks to do phrase searching.
- If you enter multiple words (or single words in multiple fields), they are treated as a default Boolean "and" so you get results that have all the words. Boolean operators ("and," "or," and "not") are ignored.
- Do not use an asterisk (*) to match partial words. The search engine automatically performs "stemming," meaning that partial-word matches should appear in search results (more info).
