Each redistricting dataset merges the electoral data the SWDB collected and processed over the preceding decade with the most current census data (PL94-171). The result is a census block level dataset that allows for longitudinal analysis of electoral data over time on the same unit of analysis. Electoral data consist of the Statements of Vote (SOV) and Statements of Registration (SOR) for each statewide election. These data are collected from the Registrars of Voters for each of the 58 California counties with each election.
The SWDB collects the Statement of Vote and the Statement of Registration along with various geography files from each of the 58 counties for every statewide election. The Statement of Vote is a precinct level dataset and precincts in California change frequently between elections. The goal of the SWDB is to make election data available that can be compared over time, on the same unit of analysis – a precinct, a census block or a census tract.
Update September 28, 2011 - The California Citizens Redistricting Commission completed the line-drawing process and certified its maps to the Secretary of State on August 15, 2011.
Historically the California Legislature has been responsible for redrawing the state's legislative district boundaries. Proposition 11 (the Voters FIRST Act), passed in the November 2008 General Election, transferred responsibility for redrawing the State Senate, Assembly and Board of Equalization district lines to a new Citizens Redistricting Commission. In November 2010, voters passed Proposition 20 (the Voters FIRST Act for Congress), adding drawing the boundary lines for the Congressional districts to the responsibilities of the Citizens Redistricting Commission. The Commission was required to draw all four maps by August 15, 2011.
California's first Citizens Redistricting Commission (CRC) is a 14-member Commission made up of five registered Democrats, five registered Republicans, and four California voters registered with no party at all (‘decline-to-state’). The Commission was tasked with drawing Congressional, State Senate, Assembly, and State Board of Equalization districts in conformity with specific criteria outlined in Propositions 11 and 20 and now in the California Constitution. The full Commission was selected on December 15, 2010, and after a very early resignation and replacement, the full commission (see below) had been sworn in by February 10, 2011. The Commissioners serve for ten years. Go here to see the meeting notices and agendas and here to view all meetings recorded and archived on the CRC website.
