> The race numbers make a lot more sense when you look at it in context of local base rates. About 50% of engineers in Silicon Valley are white and about 30% are Asian. That's approximately the same as the demographics of San Francisco, San Mateo and Alameda counties. That probably has more to do with the numbers of people who move to those areas specifically for tech jobs. The demographics you describe did not just occur naturally - they are driven by SV employers hiring from all over the world. According to http://www.washingtonexaminer.com/37-percent-of-silicon-valley-foreign-born/article/2583195 http://www.washingtonexaminer.com/37-percent-of-silicon-vall... 37% of the population of Silicon Valley isn't even born in the US, much less the urban areas of California.
