California has a diverse population with a large Hispanic segment. The exact number of California's total and immigrant population is not provided, but there are estimates of roughly 11 million undocumented immigrants in the US, many of whom are in California.
Step-by-step explanation:
The total population of California is not explicitly stated in the referenced texts, but the information provided points to significant ethnic diversity and a substantial number of immigrants. The state has a large Hispanic population, constituting 37% of its residents, while 42% are non-Hispanic white, and 7% are African American. Regarding the foreign-born population and undocumented immigrants, as of 2012, there were approximately 11.7 million undocumented immigrants in the United States, with a substantial number living in California. Earlier, in 2008, estimates suggested that there were about 11 million undocumented immigrants in the U.S., with figures ranging broadly from 7 to 20 million. It's also known that the majority of these undocumented immigrants originate from Mexico (56%) and other Latin American countries.
