California
Population

Presently, close to one out of every nine United States residents lives in California. The United States Census Bureau reported that the population of California was 39.54 million on April 1, 2020, a 6.13% increase since the 2010 census. During that decade, the state's population grew more slowly than the rest of the nation, resulting in the loss of one seat on the US House of Representatives, the first loss in its entire history. The estimated state population in 2023 was 38.94 million. For well over a century (1900 – 2020), California experienced steady population growth. Even while the rate of growth began to slow by the 1990s, some growth continued into the first two decades of the 21st century; California added an average of around 400,000 people per year to its population during the period 1940–2020. Then in 2020, the state began to experience population declines continuing every year, attributable mostly to moves out of state but also due to declining birth rates, COVID-19 pandemic deaths, and less internal migration from other states to California. According to the U.S. Census Bureau, between 2021 and 2022, 818,000 California residents moved out of state with emigrants listing high cost of living, high taxes, and a difficult business environment as the motivation. The net loss of population in California between July 2020 and July 2023 was 433,000.

The Greater Los Angeles Area is the second-largest metropolitan area in the United States (U.S.), while Los Angeles is the second-largest city in the U.S. Conversely, San Francisco is the most densely-populated city in California and one of the most densely populated cities in the U.S.. Also, Los Angeles County has held the title of most populous U.S. county for decades, and it alone is more populous than 42 U.S. states. Including Los Angeles, four of the top 20 most populous cities in the U.S. are in California: Los Angeles (2nd), San Diego (8th), San Jose (10th), and San Francisco (17th). The center of population of California is located four miles west-southwest of the city of Shafter, Kern County.

As of 2019, California ranked second among states by life expectancy, with a life expectancy of 80.9 years.

Starting in the year 2010, for the first time since the California Gold Rush, California-born residents made up the majority of the state's population. Along with the rest of the United States, California's immigration pattern has also shifted over the course of the late 2000s to early 2010s. Immigration from Latin American countries has dropped significantly with most immigrants now coming from Asia. In total for 2011, there were 277,304 immigrants. Fifty-seven percent came from Asian countries versus 22% from Latin American countries. Net immigration from Mexico, previously the most common country of origin for new immigrants, has dropped to zero / less than zero since more Mexican nationals are departing for their home country than immigrating.

The state's population of undocumented immigrants has been shrinking in recent years, due to increased enforcement and decreased job opportunities for lower-skilled workers. The number of migrants arrested attempting to cross the Mexican border in the Southwest decreased from a high of 1.1 million in 2005 to 367,000 in 2011. Despite these recent trends, illegal aliens constituted an estimated 7.3 percent of the state's population, the third highest percentage of any state in the country, totaling nearly 2.6 million. In particular, illegal immigrants tended to be concentrated in Los Angeles, Monterey, San Benito, Imperial, and Napa Counties—the latter four of which have significant agricultural industries that depend on manual labor. More than half of illegal immigrants originate from Mexico. The state of California and some California cities, including Los Angeles, Oakland and San Francisco, have adopted sanctuary policies.

According to HUD 's 2022 Annual Homeless Assessment Report, there were an estimated 171,521 homeless people in California.
