California’s population growth has chilled to its slowest advance in 80 years, as births and foreign immigration cooled and outflows to other states and deaths heated up.

The state Department of Finance, in its population update as of July 1, found 39.96 million Californias — that’s up 141,000 in a year, the smallest increase since 1939. Last year’s population growth was down 86,000 from 227,000 in 2018 and below the 283,000 averaged a year in the decade.
