​This fact sheet looks at 14 micro-communities within California engaged in innovative efforts to improve health and well-being as part of the "Building Healthy Communities" (BHC) initiative of The California Endowment. The authors find that three-fourths of uninsured children and parents in the BHC sites will be eligible for coverage under health care reform. The findings are based on a 2009 California Health Interview Survey (CHIS 2009) oversample of the 14 communities.
