Voter Registration in the United States Series
Investigator(s): Inter-university Consortium for Political and Social Research (ICPSR)
The Voter Registration in the United States series was developed by ICPSR in 1968 from official and unofficial voter registration tabulations by state governments. The primary funding for this series was provided by the National Science Foundation. The purpose of this data series was to furnish additional research data on registration trends, the relationship between registration and voting, the role and strength of political parties, and the degree of partisan competition. County-level voter registration information is available for 48 states (North Dakota does not require registration and Wisconsin does not report statewide voter registration figures). These data tabulate the number of registered voters who were eligible to cast ballots in biennial national elections in the United States between 1968 and 1988. Where available, county-level totals are also presented for registration by race, major or minor political party, or other similar category provided by the reporting agency of the state.
