If the US as a whole is a melting pot of people, California is an ethnic microcosm. It receives the highest number of immigrants (more than 200,000 annually), and the racial make- up is the most diverse in the nation. The percentage of whites and African-Americans is lower than the national average, but the Asian residency is more than triple the national level. Hispanics account for more than a quarter of all Californians - three times the US average.
