How the NationBuilder voter file differs from a county voter file

NationBuilder acquires voter data directly from county and state election offices, so a lot of the information included is the same. After acquiring voter data, NationBuilder aggregates and standardizes the data across different counties and states to deliver it to you in a format that is easy to use.

A district or county voter file requested from NationBuilder is free. On the other hand, many county and state election offices charge for voter data and the costs vary. Prices range from a simple $5 processing fee to $29,000.

Municipal elections that take place on different days than statewide or national elections may not be included in the NationBuilder voter file. Contact your community strategist or email to clarify which elections are available in your district. You may be able to acquire the additional vote history data from your county or state elections office.
