Maine

Types of Data

The data available for our states are Precinct Boundary and Election Results, Aggregated Voter File Data, Incumbent Addresses (by request), Population Projections, PL 94-171, Legislative Boundaries, American Community Survey (ACS), Citizen Voting Age Projections (CVAP) and TIGER Boundary files. Learn more about our data and if you need a redistricting dataset we don’t have, let us know what you need and why

This state does not have constitutional or statutory requirements for modifying the PL 94-171 data prior to redistricting. However, this state may still make modifications to the data prior to redistricting, and thus we cannot guarantee the data hosted on this website is identical to the data used by the official redistricting body or bodies in this state. For more information about state modifications, visit our State Modifications Report
