Population of California 2021
California has been the most populous US state since 1962; today it has twice as many residents as New York State, which was the most populous until then.
Along with Texas, New Mexico and Hawaii, California is one of four so-called majority minority states, states in which non-Spanish-speaking whites make up less than 50 percent of the population. More than 200 languages are spoken in California, with Spanish being the second most widely spoken language after English. Spanish is widely used, especially in Southern California, where Hispanic immigrants are particularly strong due to the border with Mexico. Demographic projections assume that California will have a Hispanic majority population in 2020, due to both higher birth rates and higher immigration rates.
California is the second most populous (member) state in the western hemisphere, surpassed only by the Brazilian state of São Paulo. If California were its own country, it would be the 34th most populous state in the world, ahead of Canada and Australia, which are significantly larger in area.
