Mapping California's Politically Vulnerable Communities


On this page you will find a series of Static GIS Maps visualizing California communities’ voter turnout. These non-interactive maps include: 

Hot Spot Maps:  These maps identify ‘hot spots’ of Politically Vulnerable Communities, which are defined by the CCEP as low-turnout communities where residents face multiple disadvantages in terms of economic, educational and health outcomes (based on the CCEP’s calculated Index of Political Vulnerability).*

Two-layer Maps:  These maps show registered voter turnout overlaid with individual economic, educational and health outcome data.  Factors examined include education (low high-school graduation rates, a lack of post-secondary education), economic factors (poverty, high unemployment rate, not having access to a vehicle), health (poor environmental health, high teen birth rates, premature mortality) and civic access (limited English proficiency, percent of eligible voters).  

Registered Voter Turnout Maps (one-layer maps):  These maps present the registered voter turnout of Latinos and Asian-Americans, and of the general population in California.  Detailed static maps offer a statewide geographic view, and cover five key regions: the San Francisco Bay Area, the San Joaquin Valley and the greater Los Angeles, Sacramento, and San Diego areas.  

*The CCEP’s Index of Political Vulnerability is calculated with educational, economic, and health measures commonly associated with disadvantaged communities and low voter turnout.  CCEP’s Hot Spot Maps provide a clear picture of how and where Political Vulnerability is greatest in the Golden State.  For more information on the methodology used in this mapping research, click here.
