From March 1 through August 22, 2020, 146 557 deaths were recorded in California, with an estimated 19 806 (95% prediction interval, 16 364-23 210) deaths in excess of those predicted by historical trends (Table). Per capita excess mortality was highest among people aged 65 years and older, men, Black and Latino residents, and those without a college degree. Comparing deaths in March through April vs May through August, Latino residents and those without a high school degree or general education development (GED) certificate had the greatest increase in excess deaths, with Latino deaths tripling (from 16 to 51 excess deaths per million) and deaths in those without a high school degree/GED increasing by a factor of 3.4 (from 21 to 72 excess deaths per million). Across age groups, younger adults had the greatest increases in excess death, with rates more than doubling between shutdown and reopening (age, 25-54 years: from 4 to 11 excess deaths per million, 55-64 years: from 12 to 30 excess deaths per million).
In most weeks of the pandemic, Black residents had higher per capita excess mortality than other racial/ethnic group (Figure). Late in the shelter-in-place period, White, Asian, and Black residents had a decline in excess per capita mortality. In contrast, Latino residents and those without a high school degree/GED saw a substantial and sustained increase in per capita mortality.
