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.
This is a page containing links to all of the pre-2000 General election conversion files in the Statewide Database. They are only available as-is: that is, the files here are exactly those provided by the data contractor. Below you will find a matrix of election and conversion types. The geography type on the far left is that into which you want to resolve your data, that is, the unit of analysis in which you want to translate your data. The geographic indicator immediately to the right of this one is that from which you wish to convert. Next, a list of available conversions are shown. Click on the county or district number in which you are interested to download the corresponding geography. Note that if you see two identical labels, one will download a DAT file and one will download a DBF file.
Documentation and diagrams explaining the precinct file types and conversions can be found on this page.
