Restricted-Use Data Access

ANES items identified as Restricted-Use Data are not publicly released but can be requested for the purpose of scientific and public policy research. ANES Restricted-Use Data are not available directly from ANES.  The Inter-university Consortium for Political and Social Research (ICPSR) handles applications for ANES Restricted-Use Data and provides access to the data through their Virtual Data Enclave (VDE), a secure, virtual environment that is accessible from your own desktop computer.

Application Process in Brief

  1. Choose one of the ICPSR links below to start an application.
  2. Locate and click on the “Access Restricted Data” tab to begin.
  3. Enter your contact information, project title, description and an abstract of 250 words or less in length.
  4. Select the data files and analysis software you require. Please note: You can select multiple ANES restricted-use files in one application.
  5. Click “create project.”
  6. Check your email for the confirmation notice which will include a link to the ICPSR VDE Data Use Agreement.
  7. Follow the application instructions in the confirmation notice and email your IRB documentation and completed Data Use Agreement to icpsr-help@umich.edu.
  8. Once your request is approved, ICPSR staff will be in contact with you to set up your VDE license and account, as well as a quick training of how to use the VDE.

Geocode data for ANES Time Series studies conducted prior to 1978 are already available (unrestricted) in the public release of the studies; there are no restricted-use geocode data files for the 1948-1976 Time Series studies. The same variables are present in each “standard” RDA geocode file for ANES Time Series studies 1978 and later. In any one of these files, however, there may be no data in some of the variables; for example, the variable for Minor Civil Division has no data in the 1980 and 2012 “standard” RDA geocode files because MCD codes were not available during those years. See which variables are available for each Time Series study.

It should be noted that the ANES Time Series Cumulative Data File, which combines data from different Time Series studies for many questions that have been asked in multiple Time Series years, does not have a prepared “standard” RDA geocode file or RDA zip code file covering all years of the Time Series. A “standard” RDA geocode file or zip code file must be requested for individual Time Series study years.

Full Census Occupation and Prestige Scores

1986-2004 Full Census Occupation and Prestige Scores

There are no RDA data files of Census Occupation codes or prestige scores for any Time Series studies 1984 or earlier, or for Time Series studies after 2004. Prior to 1986, all occupation codes were made available in the Time Series public releases. Prior to 1976, these included data coded from master code sets other than U.S. Census Occupation Codes (e.g. Political Behavior Occupation Codes, which were not identical but corresponded closely to Census Occupation codes). In 1976, ANES began utilizing U.S. Census Occupation Codes to code open-end texts of respondent descriptions of occupation, and the full 3-digit Census codes were made available unrestricted in Time Series public releases 1976-1984.

Beginning in 1986, in the interest of protecting respondent anonymity, ANES began collapsing the full 3-digit Census Occupation Codes to a standard 71-category (2-digit) version for Time Series public releases. This practice continued until use of master Census Occupation codes from the 1980 and 1990 Censuses was replaced by use of master codes from the 2000 Census. The complete Census Bureau overhaul of Census Occupation Codes for the 2000 Census produced a new master code set without relation to the set used in the preceding two Censuses. For the 2004 Time Series public release, no version of the occupation codes from the 2000 Census, including any collapsed version, could be included in the public release, however variables were added to the release which provided the usual 71-category collapse of full occupation coding based on categories from the 1990 Census. Full 1990 Census occupation codes are available as RDA data for the 2004 Time Series study, as well as full 2000 Census occupation codes.

Open-Ended Responses

Open-Ended Responses files contain respondents’ exact responses to open-ended questions that have appeared in ANES surveys. Previously these files were only available through a restricted data application process.

Since then, responses within select Open-Ended Responses files have been redacted to remove identifying information and are now publicly available. The redacted files can be downloaded from the ANES website at the indicated locations. No restricted data application is necessary for the following files.

  • The ANES 2020 Time Series study page includes redacted files for Timing of Vote Decision, Likes-Dislikes, Office Recognition, and Most Important Problem.
  • The ANES 2016 Time Series study page includes redacted files for Likes-Dislikes, Industry/Occupation, Social Class, Party Contact, Office Recall, Most Important Problem, and Closest Party.
  • The ANES 2012 Time Series study page includes redacted files for TIming of Vote Decision, Likes-Dislikes, Social Class, Home Ownership, Party Contact, Industry/Occupation, Home Ownership, Office Recall, Most Important Problem, and more.
  • The ANES 2008 Time Series study page includes redacted files for Likes-Dislikes, Industry/Occupation, Vote Decision, Office Recall, Why Candidate Nominated/Won/Loss, Most Important Problem, and Reason for 9/11 Attack.
  • Likes-Dislikes for the ANES 1984-2004 Time Series studies have been redacted and are all stored in a single file that can be downloaded, for example, from the ANES 2004 Time Series study page.
  • Most Important Problem for the ANES 1984-2000 Time Series studies have been redacted and are all stored in a single file that can be downloaded, for example, from the ANES 2000 Time Series study page.

Additional Open-Ended Responses files are not yet available, in redacted or unredacted form. Requests to make additional Open-Ended Responses files available can be submitted by email to anes@electionstudies.org. Our ability to fulfill these requests depends upon data availability, difficulty (some older open-ends are not yet transcribed, for instance), and prioritization among other project activities.
