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.

Tulsa County commissioners Monday approved new district boundaries.
The county's three districts are redrawn every 10 years to reflect new Census figures.
Tulsa County's population grew by 40,104 people between 2000 and 2010, from 563,299 to 603,403. More than 75 percent of the growth took place in Districts 1 and 3, with District 2's population growing by 6,086 people.
According to the Census, District 1 had the largest population with 206,001 people; District 2 has the smallest population with 193,901 people.
The objective of the redistricting process, as set forth in state law, is to create clearly definable districts that are compact and as equal in population as is practical.
Given the new Census figures, the ideal population for each of the three districts is 201,134.
Each district approved Monday is within 400 of the ideal population.
County commissioners - working one at a time with the Indian Nations Council of Governments staff - drew up the district boundary proposal.
