This document compares maps of uninsured populations to minority populations in California counties. Several counties with the highest percentages of Black and Hispanic residents also had large percentages of uninsured residents. However, the counties with the highest percentages of uninsured residents did not always correspond to those with large minority populations. The correlation was stronger between uninsured and Hispanic populations than between uninsured and Black populations. Additional factors like employment rates should be examined due to the lack of a perfect correlation.
