Overview

What is voter history? When voters present to vote, they receive a ‘voter history’ entry on their voter record documenting their participation in that election; this entry includes voter county, precinct, and voting method.

Current Voter History Data
What’s included? Files contain a data entry for each election in which a voter participated in the past 10 years. Voter registration number, NCID, party affiliation, county, and precinct, as well as voting method (e.g., in-person on Election Day, absentee by mail) are included. See file layout for full list of variables.
Important note: The county-level voter history files contain the data for voters currently registered in the given county. As such, to get accurate numbers for voter history around a specific election, users should download the statewide file and use the voted_county_desc column to filter, instead of downloading the relevant county file.
What’s not included? Voter names and demographics are not included. However, the files are linkable (via NCID or county and voter registration number) to the Voter Registration Data files, which do contain voter names and demographics.
When are the files updated? Files are updated weekly on Saturday mornings. After each election, it may take multiple weeks for all 100 counties to finalize their voter history.
Historical Voter History Stats

What’s included? You can view the number of North Carolina voters who participated in a specific election, broken down by county, precinct, voting method, and voter demographics: party affiliation, race, ethnicity, sex, and age. For primary elections, the party voted (i.e., party primary in which the voter participated) is also included. See layout file (.txt) for full list of variables.
What’s not included? Individual voter-level data are not included. Candidate/ballot item choices are not included. Election results are not included.
When are the files updated? A file is generated for each election. After the election, it may take multiple weeks for all 100 counties to finalize their voter history.
When voters present to vote, they receive a ‘voter history’ entry on their voter record documenting their participation in that election; this entry includes voter county, precinct, and voting method.
During the weeks after an election, counties work to finalize their voter histories. Once a county’s voter history is finalized, the data will be published in the Current Voter History files the Saturday after that finalization (since these files update weekly, each Saturday).
In other words, if 5 counties finalize their voter histories during the first week after any election, those 5 counties’ voter history data will show up in the Saturday refresh of the Current Voter History files.
