Other tongues overtaking English as language spoken in majority of Santa Clara County homes

The San Jose Mercury reports:

As it grows as a global technology hub, Silicon Valley has become one of the most polyglot places in the United States. Santa Clara County is on the brink of a linguistic milestone: Within the next few years, more people will speak a foreign language at home than the number who speak English, recently released census data shows. Given the statistical uncertainty, that threshold may already have been crossed.

Santa Clara County has the largest population of Hindi speakers among all counties in the United States, the second-largest population of Vietnamese speakers, the third-largest population of Persian/Farsi speakers, and the fifth biggest number of Chinese speakers, a Mercury News analysis of 2005 census data shows. In percentage terms, the county ranks first in Vietnamese speakers, second in Hindi, third in Chinese and fourth in Persian/Farsi.

Since 2000, Santa Clara County has passed Los Angeles and San Francisco to become the California county with the highest percentage of immigrants, with 36 percent of its population born outside of the United States.

We get the feeling that many Americans who were born in America are going somewhere else.
