It's Black and White

Wolfram Alpha is a great way to play with statistics. Here's something from the US 2000 census.

The surname White is the 20th most common, Black the 160th.

Cross tabulating with ethnicity 77% of the Blacks are white, but only 68% of the Whites are white.
19% of the Blacks are black while 27% of the Whites are black.

Put another way, for the whites there are more Blacks than Whites, for the blacks its the other way round.

Still confused?  Here's the tabulation.
