State Legislative District Upper Chamber
About State Legislative District Upper Chamber
State legislative districts are the areas from which members are elected to state or equivalent entity legislatures. The state legislative district embodies the upper (senate - SLDU) and lower (house - SLDL) chambers of the state legislature. The Census Bureau first reported data for state legislative districts as part of the 2000 Public Law (P.L.) 94-171 Redistricting Data File for the states that choose to submit them.
State legislative districts (2010 Election Cycle)
States participating in Phase 1 of the 2010 Census Redistricting Data Program, as part of P.L. 94-171, voluntarily provided the Census Bureau with the 2006 election cycle boundaries, codes, and in some cases names for their state legislative districts. All 50 states, plus the District of Columbia and Puerto Rico, participated in Phase 1. States subsequently provided legal changes and/or corrections to those plans through the Census Bureau's Redistricting Data Office or as part of Phase 2 of the 2010 Redistricting Data Program.
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.
State Legislative District Codes
A unique 3-character census code, identified by state participants, is assigned to each state legislative district within a state. In Connecticut, Hawaii, Illinois, Louisiana, Maine, Maryland, Massachusetts, New Jersey, Ohio, and Puerto Rico, the state participant did not define the current state legislative districts to cover all of the state or equivalent area. In states other than Maryland, the code "ZZZ" has been assigned to areas with no state legislative districts defined (usually water bodies). These unassigned areas are treated within state as a single state legislative district for purposes of data presentation. In Maryland, the code "Z**", where "**" represents the last two digits of the county code, has been assigned to areas with no state legislative district defined. These unassigned areas are treated within county as a single state legislative district for purposes of data presentation. ;
