Never mind the 40 million that demographers predicted the Golden State would reach by 2018. The state's population dipped below 39 million to 38.965 million last July, according to Census data released in March, the lowest since 2015.

Projections are just that. Case in point – California population.
“Forty million people will live in California by the end of 2018 and 50 million by 2048, the state Department of Finance said in estimates released Tuesday,” reported The Mercury News on May 8, 2012.
And then there's reality.
“The U.S. Census Bureau reported in March that California’s population as of last July had dropped to an estimated 38,965,000,” wrote George Skelton, Capitol Journal columnist for the Los Angeles Times on April 8. “That’s down by 75,400 in a year — and 573,000 below California’s peak of 39.5 million in 2020.”
[Correspondent's note: The Census Bureau released county data on March 14. The July 2023 population is the same as the estimates posted last December, noting the state's 2015 population.]
Domestic migration
Skelton offers a number of reasons for the three-year population decline, including a questionable “carrying capacity" explanation, before adding:
But “the biggest reason we’re losing population is that people are moving out,” says [Hans Johnson, a demographer at the nonpartisan Public Policy Institute of California]. “That has slowed, but we’re still losing hundreds of thousands to other states.” That’s a net loss after factoring in people moving to California.
And why are they leaving? Mainly because of California’s high cost of living, particularly housing. That’s the biggest reason movers cite.
While domestic migration “is the main cause of California’s continuing population loss,” it is not the only factor, adds Skelton.
“California’s fertility rate has fallen faster than most [states],” the public policy institute reported in October. “In 2008 its rate was above the national average (2.15). By 2020, it fell to the seventh lowest (1.52).”
Is California too blue?
According to the California Community Poll, an ongoing partnership between Strategies 360 and the Los Angeles Times, the state's politics and policies play a role as well.
“Nearly 30% of [California residents] surveyed said they might leave because the state’s policies and laws don’t align with their political views, a reflection of the polarization of the state and the nation at the moment,” reported the Times on June 23, 2023.
That's consistent with the findings of a policy brief, “California's population drain," published October 2023 by the Stanford Institute for Economic Policy Research, that found that "[t]wo-thirds of those who moved said that politics was not a factor in their decision.” The researchers add under 'key takeaways':
- California’s environmental policies and mandates could fuel the economic and political exodus to more lenient states like Arizona and Texas.
Hat tip to the Los Angeles Times 'Essential California' newsletter, April 8: “California is still losing Californians. It’s no mystery why.”
