According to the 2000 census, 50.9% of the US is female, 75.1% of the US is white, and 12.3% of the US is black.
Does it necessarily follow that in an ideal non-prejudiced society, in any specific job type averaged over the nation, 50.9% of the employees would be female, 75.1% of the employees would be white, and 12.3% of the employees would be black?
Quick summary . . .
The question is invalid (explain why, please?)
I don't know
I've set it so other people can't see your specific reply - I'm mostly interested in the statistical data, not who-said-what. On the other hand, if you've got specific comments, I'd love to hear 'em :P
