Elections History and Voter Registration Data

  • Use of Elections data (election results and voter registration numbers) is required to comply with both federal and state law, in a manner consistent with the 14thAmendment of the U.S. Constitution.  Specifically, Elections data is required to comply with:
    • Sections 2 and 5 of the federal Voting Rights Act; and
    • Florida’s Constitution, Article III, Sections 20(a) and 21(a), which both read, “districts shall not be drawn with the intent or result of denying or abridging the equal opportunity of racial or language minorities to participate in the political process or to diminish their ability to elect representatives of their choice;”.
  • By Census Block, these are the 2006 and 2010 General Election results and 2010 voter registration numbers from the Secretary of State and Florida’s 67 Supervisors of Election.  We used aerial interpolation to allocate numbers to the block level, so you will see parts-of-people at the census block level.  We also included census county, VTD (voter tabulation districts) and block names in the data to make it easier to work with.  Download the data as used in MyDistrictBuilder: Click Here

    How do I find out what precincts are within a particular District, especially a newly-formed District?

    Don’t cut major communities like Panama City in half so we can never elect a represenative from here- only Pensacola or Tallahassee.
