ANES is not a source of factual population data on registration, eligibility, turnout, or vote. We are primarily a data collection organization for surveys, and all information in our data represents self-report by respondents who are selected as part of relatively small samples.

Data for population registration and turnout are collected at the state level by the state’s Election Board (which is often part of the Secretary of State office). For election result data, you can also check with the clerk of the House of Representatives.
