California Historical Growth, Statehood

Another significant factor for the California population is immigration: California had huge appeal in the days of the Gold Rush and that fact holds true today. Between those years of 2000 and 2009, the state enjoyed a net migration gain of 306,925 people. It’s also been estimated that up to approxmiately 6.3% of California’s population is made up of illegal immigrants.
California was the 31st in line to be admitted as a State in 1850. The historical first census of this state is noted because California also conducted a state census in 1852 in addition to the federal census of 1850. Both results are included in the 1850 census publications. The federal census of 1850 is missing Contra Costa, San Francisco, and Santa Clara counties. They are included in the 1852 state census however.
