This fact sheet presents county-by-county estimates of the number of California residents who have lost health insurance during the economic downturn. The authors find that the number of Californians without health insurance grew in all counties and that 37 counties — from Imperial to Kern to Shasta — had uninsured rates above the statewide average of 24.3%.

Loss of health insurance was concentrated in Southern California (Imperial, Riverside, San Bernardino counties), the San Joaquin Valley (all counties), and the Northern/ Sierra areas (all but Sutter and Humbolt), all of which had 2009 uninsured rates that were above the statewide average (24%).

The losses were due to sharp increases in local unemployment and corresponding drops in both household income and job-based coverage.
