Geographic Area Description

State legislative districts (SLDs) are the areas from which members are elected to state legislatures. The SLDs embody the upper (senate) and lower (house) chambers of the state legislature. (Nebraska has a unicameral legislature and the District of Columbia has a city council, both of which the U.S. Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation. Therefore, there is no data by lower chamber for either Nebraska or the District of Columbia.) A unique census code of up to three characters, identified by state participants, is assigned to each SLD within state. The code "ZZZ" identifies parts of a county in which no SLDs were identified.

SLDs are provided to the Census Bureau as part of the Redistricting Data Program. Participation by the states is optional; not all states provided their SLDs for 2000.
