In the 20th century, thousands of Japanese people migrated to California. The state in 1913 passed the [[California Alien Land Law of 1913|Alien Land Act]], excluding Asian immigrants from owning land.<ref>{{Cite web |title=The U.S. Mainland: Growth and Resistance |url=https://www.loc.gov/classroom-materials/immigration/japanese/the-us-mainland-growth-and-resistance/ |website=Library of Congress}}</ref> During World War II, [[Internment of Japanese Americans|Japanese Americans in California were interned]] in concentration camps;<ref>{{Cite web |title=Behind the Wire: Japanese Immigration and Relocation in U.S. History |url=https://www.loc.gov/classroom-materials/immigration/japanese/behind-the-wire/ |access-date=February 8, 2021 |website=Library of Congress}}</ref> in 2020, California apologized.<ref>{{Cite web |last=Dil |first=Cuneyt |date=February 20, 2020 |title=California apologizes for Japanese American internment |url=https://apnews.com/article/4b9234383de4814974f81e78a1edaa95 |access-date=February 8, 2021 |website=AP NEWS}}</ref>

Migration to California accelerated during the early 20th century with the completion of transcontinental highways like the [[U.S. Route 66 (California)|Route 66]]. From 1900 to 1965, the population grew from fewer than one million to the greatest in the Union. In 1940, the Census Bureau reported California's population as 6% Hispanic, 2.4% Asian, and 90% non-Hispanic white.<ref>{{Cite web |title=California—Race and Hispanic Origin: 1850 to 1990 |url=https://www.census.gov/population/www/documentation/twps0056/twps0056.html |archive-url=https://web.archive.org/web/20141224151538/http://www.census.gov/population/www/documentation/twps0056/twps0056.html |archive-date=December 24, 2014 |publisher=U.S. Census Bureau}}</ref>

To meet the population's needs, engineering feats like the [[California Aqueduct|California]] and [[Los Angeles Aqueduct]]s; the [[Oroville Dam|Oroville]] and [[Shasta Dam]]s; and the [[San Francisco–Oakland Bay Bridge|Bay]] and [[Golden Gate Bridge|Golden Gate]] Bridges were built. The state government adopted the [[California Master Plan for Higher Education]] in 1960 to develop an efficient system of public education.

Meanwhile, attracted to the mild Mediterranean climate, cheap land, and the state's variety of geography, filmmakers established the [[studio system]] in Hollywood in the 1920s.

Although air pollution has been reduced, health problems associated with pollution continue.

Housing prices in urban areas continued to increase; a modest home which in the 1960s cost $25,000 would cost half a million dollars or more in urban areas by 2005. More people commuted longer hours to afford a home in more rural areas while earning larger salaries in the urban areas. Speculators bought houses, expecting to make a huge profit in months, then rolling it over by buying more properties. [[Mortgage]] companies were compliant, as people assumed prices would keep rising. The [[subprime mortgage crisis|bubble burst]] in 2007–8 as prices began to crash. Hundreds of billions in property values vanished and foreclosures soared, as financial institutions and investors were badly hurt.<ref>Robert M.
