ANES 2020 Time Series Study Geocodes

This study is part of the American National Election Studies (ANES), a time series collection of national surveys fielded since 1948. The American National Election Studies are designed to present data on Americans' social backgrounds, political predispositions, social and political values, perceptions and evaluations of groups and candidates, opinions on questions of public policy, and participation in political life. The files included in this study are restricted-use due to the geocodes contained in them for the year listed in the title. Please review the contents of the ZIP file ANES_RDS_Documentation_Geocodes.zip for helpful information about the meanings of variables and changes to geocoding over time. Should you need to merge datasets across the 1992-1997 or 2000-2004 panel, ID bridging files for those panels are also included in the same ZIP file.
