Mapping California's Politically Vulnerable Communities

Interactive Maps - 2012 General Election

The CCEP's new mapping tool allows users to identify areas of high and low voter turnout, down to the neighborhood precinct level.  These interactive maps also allow users to investigate the interplay between electoral participation and economic, educational and health outcomes. Please see our Interactive 2012 General Election Maps below. Click here for our Interactive 2014 General Election Maps. 

Also available from the CCEP are a series of Static GIS Maps visualizing the relationship between low voter turnout (total, Latino and Asian-American turnout) in California communities and economic, educational and health challenges.
