California is the most populous state in the nation. With slightly more than 39 million people (according to 2016 estimates), California is the nationâs most populous stateâits population is almost one and a half times that of second-place Texas (28 million). One of every eight US residents lives in California. By 2050, Californiaâs population is projected to reach 50 million people. During the 20th century, California experienced tremendous population growth â¦ In 1900, California was home to less than 2 million people; by 1950 the population had reached 10 million. Californiaâs population nearly tripled in the last half of the 20th century, and its growth rate remained much higher than that of the rest of the United States.
â¢ Migration will account for a small share of growth. Before 1990, most of Californiaâs population growth came from migration, primarily from the rest of the United States. Since 1990, most of the stateâs growth has been from natural increase, that is, the excess of births over deaths.
