I was reading this article in the NY Times on the lack of diversity in the boards of New York City cultural institutions, and I was struck by this statistic:

To be sure, there are still far fewer rich blacks than rich whites — 33,000 black households have an income of $150,000 or more in the New York metropolitan area, compared with 587,000 white households in the same income bracket, according to an analysis of 2000 census data by the Queens College department of sociology.
