Counties with the lowest life expectancy in California

Among 57 California counties with published values, the counties with the lowest life expectancy are Siskiyou County, CA (73.1, against the U.S. county median of 75.3), Del Norte County, CA (73.8, against the U.S. county median of 75.3) and Lake County, CA (74.1, against the U.S. county median of 75.3). Values are years.

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.
