Elections and Voting Data Guide: United States (U.S.) and International

Data, statistics, media, and other resources on elections and voting, turnout, campaigns and nominations, electoral administration, and more, both in the United States and internationally.

Global Coverage of Results

Several datasets on parties and parliaments also have election data combined with numerous variables coding parties.

Single or Multi-Country Results

Precinct- / Below the Constituency-level Returns

Finding voting results below the level of the electoral constituency/district (i.e., the level at which seats are distributed) can be very challenging. Each country reports at different levels of geographic aggregation. I have placed links to the lowest level I could find, which in all cases is below the constituency level. Emphasis is on parliamentary (specifically the lower house) elections.

Europe

  • European Election Database (This covers a higher geographic level, but allows comparison of elections in 35 countries over 20 years at NUTS levels 1-3 to facilitate comparison with Eurostat regional statistics.)

Denmark

Finland

France

  • Data.gouv.fr (Google Translate version) hosts a variety of French elections—presidential, legislative (Assemblée nationale), municipal, cantonal, European—in Excel or .csv format for a variety of geographies—circonscription (constituency), région, département, commune (municipality), canton, and bureaux de vote (polling station)—generally 1990s-present, but legislative back to 1958.

Germany

Mexico

  • Electoral Precinct-level Database for Mexican Municipal Elections, 1994-2019. Compiles and standardizes electoral precinct-level returns for municipal elections from 1994 to 2019 in 31 Mexican states (excluding Mexico City), comprising 456,051 precinct-level electoral returns for 15,581 municipal elections, 62,341 unique electoral precincts, and 2,033 unique municipalities. Includes data for all electoral coalitions in each election and votes for the coalitions of the party of the incumbent mayor, the party of the state incumbent governor, and the four most popular political parties. Also provides valid and total votes per precinct as well as voter turnout where available. Data in .csv. See the accompanying paper for details: Calderón-Hernández, B., Larreguy, H., Marshall, J. et al. Electoral precinct-level database for Mexican municipal elections. Sci Data 12, 582 (2025). https://doi.org/10.1038/s41597-025-04918-9.

Spain

  • The Spanish Electoral Archive holds all the results recorded from General (1979–2019), Regional (1989–2021), Local/Municipal (1979–2019), and European Parliamentary (1987–2019) elections held in Spain since the restoration of democracy in the late '70s. Results are provided at the following levels in most cases: mesas (ballot boxes), secciones (Census sections), distritos (Local districts), municipios (municipalities), provincias (provinces), and CCAA (autonomous regions). Data are best downloaded in the original Microsoft Excel workbook format.
