ANES produces high quality data from its own surveys on voting, public opinion, and political participation.

The Collaborative Multi-Racial Post-election Survey is a multi-racial, multiethnic, multi-lingual, post-election online survey examining race, ethnicity, and politics in the United States. Data for the CMPS were collected between December 2016 and February 2017. This dataset has restricted-use data and includes a nationally representative sample of 10,146 survey respondents.

This organization collects data on the demographics of every elected official in office in order to study trends in who represents the American public (contains data from 2014-2024).

Includes biographical information about state lawmakers who held office in 21-22, 23-24. Compiled from legislative and campaign websites and other online sources. The project's principal aim was to record the current or most recent main occupation (outside of elected office) held by each member, but the dataset also includes information about a wide range of characteristics including race, gender, and education.
