VENTURA - According to California's Department of Finance (DOF), the state grew by "only" 141,300 over the last year, but that was only because of a net outflow of almost 200,000 Californians to other states. The official state estimate for July 1, 2019, puts California's population at 39.96 million, a growth rate of 0.35 percent, the lowest recorded rate since 1900.
The DOF estimate indicates that the net domestic outmigration of 198,000 was offset by foreign immigration of 158,000 and natural increase (births minus deaths) of 181,000. Immigration drives population growth in the U.S., and even more so in California. According to the Pew Research Center, "Future immigrants and their descendants… are projected to account for 88 percent of the U.S. population increase," between 2015 and 2065.
