Everyone's heard of the voter file.
But what exactly is it?
At its core, "the voter file" is a list of registered voters in a particular area.
The file typically includes the names, addresses, phone numbers and party registration of registered voters, and what elections they've voted in. The information does vary across databases, and we'll discuss those in additional guides.
Voter files are usually compiled at the county level and are maintained by each state's Secretary of State or Board of Elections. There is a lot of variation from state to state on the voter file, so the final product that most people interact with in politics is a standardized and enhanced version of what the state maintains.
