    About Us

    To serve the research needs of social scientists, teachers, students, policy makers and journalists, the ANES produces high quality data from its own surveys on voting, public opinion, and political participation. Central to this mission is the active involvement of the ANES research community in all phases of the project.


    Our Mission

    Why does America vote as it does on Election Day? The mission of the American National Election Studies (ANES) is to inform explanations of election outcomes by providing data that support rich hypothesis testing, maximize methodological excellence, measure many variables, and promote comparisons across people, contexts, and time. The ANES serves this mission by providing researchers with a view of the political world through the eyes of ordinary citizens.

2016 Time Series Study

While we are in the process of reviewing the data and preparing it for release, we can report that we are just shy of 1,200 face-to-face respondents during the pre-election phase and over 1,050 participated in the post-election reinterview. Just under 3,100 respondents participated in the internet mode of the study and almost 2,600 completed the post-election questionnaire, however final numbers are pending verification of individual cases. We expect to have an initial release of the data late March 2017, but that's dependent on when the review of the data is completed. Please check back here or follow us on Twitter @electionstudies for updates.

Initial release expected late March

We work to update The ANES Biblography with new citations as much as possible and currently have over 7,000 citations from citations from books, books chapters, journal articles, conferences and more.

Guide to Public Opinion

The ANES Guide provides tables and graphs which display the over-time ebb and flow of public opinion, electoral behavior and choice. Data are from the ANES Time Series studies.

The ANES Guide was produced from the ANES Time Series Cumulative Data File which combines, for selected questions, data from individual Time Series study variables into common, cross-year variables. Questions which have been asked during 3 or more years in the Time Series are eligible for inclusion in the Cumulative Data File.
