Los Angeles County lost 165 people a day for five years. We ran the next century four ways
The county has lost 301,576 residents since 2020, the worst five years of any of the twenty-five largest counties in America. California’s official projection has it down another 1.4 million by 2070. Our cohort-component model ends 2070 about 808,000 below the state’s. Migration accounts for roughly 40 percent of that gap, and a higher starting count and more optimistic birth and death assumptions account for the rest.
