2018 State Legislative Block Equivalency Files

CRVRDO
Component ID: #ti481103471

These BEFs are the whole 2010 census tabulation block representations of the plans as submitted to the U.S. Census Bureau. In instances where plans included split blocks, it was requested that the state liaison identify a single district to assign the split block for use by the U.S. Census Bureau for data tabulation purposes. Each .ZIP file contains a national block equivalency file and individual state files for those states who reported changes during this collection cycle. In some instances, those reported changes were cosmetic and did not result in an actual change to the whole block assignments. The fields in these files should be imported as text to preserve leading zeros.

Notes

  • A unique 3-character census code, identified by state participants, is assigned to each state’s legislative district upper (senate) and lower (house) within a state. In Connecticut, Illinois, Louisiana, Maine, Maryland, Massachusetts, Michigan, Ohio, and Puerto Rico, the state participant did not assign the current state legislative districts to cover all of the state or equivalent area. The code “ZZZ” has been assigned to areas with no state legislative districts defined (usually large water bodies). These unassigned areas are treated within state as a single state legislative district for purposes of data presentation.
  • The state of Ohio generated their state legislative plans using custom geography from the state’s Ohio Common and Unified Redistricting Database produced by Cleveland State University. These files approximate those plans using Census Bureau geography.
  • The state of Kansas adjusted the 2010 Census P.L [94-171] redistricting data to exclude non-resident students and non-resident military personnel and to include resident students and members of the military at the place of their permanent residence for state legislative redistricting. Information on this adjustment is available on their website.
  • The state New York adjusted the 2010 Census P.L [94-171] redistricting data by reallocating state prisoner populations to their last known residence. Information on this adjustment is available on their website.
  • The state of Maryland adjusted the 2010 Census P.L [94-171] redistricting data by reallocating state prisoner populations to their last known residence. Information on this adjustment is available on their website.
  • The state of Hawaii adjusted the 2010 Census P.L [94-171] redistricting data to remove non-resident military personnel and non-resident students. Information on this adjustment is available on their website.

  • The state of New Hampshire uses floterial districts in their lower-chamber (SLDL) plan. Floterial districts are overlay districts made up of two or more discrete districts. These discrete or component districts are those represented in the New Hampshire SLDL TIGER/Line shapefile. A listing of the floterial districts and their component districts is available as a report Floterial Report and as a comma delimited text file Floterial Text File.

  • The state of Maryland will hold elections using their post 2010 Census state legislative district boundaries in 2014. Prior to those elections, sitting legislators are seated in their previously configured districts.
  • In California, only the odd numbered districts were competed in the 2012 elections for the State Legislative District Upper House (Senate) districts. The 2014 elections will include new representation in the even numbered districts. For those gaps in geographic coverage by a State senator between elections, the Senate Committee on Rules will assign a current senator until the 2014 elections are finalized.
  • Nebraska has a unicameral legislature and the District of Columbia has a single council, both of which the Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation. Therefore, there are no data by the lower house of the state legislative districts for either Nebraska or the District of Columbia.
  • The Commonwealth of Puerto Rico legislative district files are included with the state legislative districts.
