The article actually reports: Of the more than 800,000 households in Queens, according to the Census Bureau’s 2005 American Community Survey, about 39 percent are white, 23 percent are Hispanic, 18 percent are Asian, and 17 percent are black.
Interesting phenom. It's not that there are only 2 whites left in Queens, but that most of the more ambitious whites have long since realized they were in Queens, and left for Westchester and beyond, to be replaced by some of the more ambitious black West Indies and West African immigrants, for whom Queens is a step up.
The population (legal) of Queens is somewhere north of 2,000,000. If you include illegals, which abound there, the sky's the limit.
