Mapping the Gaps: Mental Health in California

About 1 in 20 adults in California suffers from a serious mental illness, though rates can vary widely by region. What other factors tied to mental illness show similar geographic variations?

July 2013

California shows wide geographic variation in rates of serious mental illness. The state's poorest areas often have the highest rates of mental illness, and they are also among the regions with the fewest licensed mental health professionals to provide treatment.

The interactive infographic below displays this geographic variation. Hover your mouse over the map and charts, and click to learn more. This data visualization is a companion to Mental Health Care in California: Painting a Picture.

About the Data

  • A serious mental illness, a categorization for adults age 18 and older, is any mental illness that results in substantial impairment when carrying out major life activities.
  • Some counties are grouped with nearby counties because their individual populations are too small to calculate comparable rates.
  • Data are plotted on a logarithmic scale, whose intervals correspond to orders of magnitude, rather than on a linear scale. Presentation of data on a logarithmic scale reduces a large range of values to a more manageable size.
  • Poverty and population data are from 2010, serious mental illness data are for 2009, and number of psychiatrists is from 2012.
