ABSTRACT
According to census figures, the U.S. population has more than doubled since 1960, and immigration has contributed significantly to this growth. Some states have been affected more than others. In California, for example, between 1990 and 2000, 9 out of 10 new Californians were Latino or Asian immigrants. In Orange County, south of Los Angeles, the population rose from just over 1 million in 1970 to more than 2.5 million in 2000. Ninety percent of the increase was the result of immigration from Mexico and Asia.
