Greatest California Population Growth from Within the U.S.

The number of foreign-born people living in California increased from about 925,000 in 1940 to nearly 1,760,000 in 1970. But the percentage of foreign-born to U.S. born residents of the state declined from 13.4 percent in 1940 to 8.8 percent in 1970. This meant that most of the millions who moved to California in this era came from within the United States.
