Counties with the highest infant mortality rates in California

Among 44 California counties with published values, the counties with the highest infant mortality rates are Siskiyou County, CA (7.8, 1.26 times the U.S. county median of 6.2), Glenn County, CA (7.7, 1.24 times the U.S. county median of 6.2) and Shasta County, CA (6.4, 1.03 times the U.S. county median of 6.2). Values are deaths under 1 per 1,000 births.

Source: County Health Rankings, built from CDC National Vital Statistics System death records. These are county-level figures, compared with the U.S. county median. A high rate does not prove an environmental cause: age, smoking, income, access to care, screening and chance all move county rates, and small counties swing widely.
