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 name, address, phone number, party registration and elections the person has voted in, among other things. This 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.
