pixie, I think I got the figure from Wikipedia, but it said it was for 2010, which was before the census. The census may have shown the same number.
The figure was for foreign-born. I expect that's not what the OP is talking about. He's been somewhere, seen non-white faces everywhere and assumed he's being overrun by aliens. But many of those may well have been born here. Conversely, many foreign-born types aren't immediately visible to the naked eye because they're white Europeans (EU or not), Americans, Australians etc
