What percentage of people who live in SV are foreign-born?

According to San Jose Business Journal, in 2003 36.5% were foreign born. http://sanjose.bizjournals.com/sanjose/stories/2003/09/01/da...

I guess/estimate if you adjusted for those native-born who are either working at family businesses already (2nd or later generation of a family owned business), or are following their parent's lead on a trade or profession (son of lawyer becoming a lawyer, daughter of ob-gyn becoming a doctor), you would find that the quoted stats are not very important or relevant.

(just adding another data point to the discussion)
