Input (English): Passage: Ethnic change has been transforming the population. By 2009, nearly 45 percent of the residents spoke a language other than English at home. Whites now comprise only 45 percent of the population, while the numbers of Hispanics grow steadily, along with Vietnamese, Korean and Chinese families. The percentage of foreign-born residents jumped to 30 percent in 2008 from 6 percent in 1970.  The mayor of Irvine, Sukhee Kang, was born in Korea, making him the first Korean-American to run a major American city. “We have 35 languages spoken in our city,” Kang observed.
