Black men have a much more favorable male/female ratio than men of other races. I’m not sure why. Possibly became blacks have a more even birth ratio, because black men die early, because black men are marrying white women, or because black men are being undercounted by the census.

Allegedly, from what I've read, Black women tend to give birth to more females, and infant deaths tend to kill off infant males more than females. Mind you, I have no way of validating such information. Supposedly, the heavily skewed male-female ratio are also able to explain why black women are willing to put up with the poor habits of their boyfriends due to the "shortage" of black men.

Black men who have children with white women tend to have children who are counted as black, so I don't think it would have an effect on the ratios at birth. Death from the violence that's common in inner city neighbourhoods is certainly what kills off the first wave of black men between 18-25, while poor health kills off the older black men.

In regards to the demographics, it is possible that the census maybe undercounting black men. I also wonder if immigration from the Caribbean has biased the counts as well. From my vantage point, it seems as if more Caribbean women immigrated to the US than men did, but I've never taken the time to determine if this hypothesis was correct.

BTW, for sampling purposes, my grandmother has 5 daughters and no sons, 9 grandchildren of which 4 are girls and 5 are boys, and 5 great-grandchildren, of which only two are boys.

I understand your color coding for all the charts except the Non-Hispanic Black chart. In the others, it's clearly that the majority is in red and the minority blue. That's not consistent for the Non-Hispanic Black chart, and nothing explains the lighter shades for the 29-32 age group.

chez, the colors show deviation from the mean listed at the bottom of the charts. One color is positive, the other negative. And the lighter or darker shades show how close or far from the mean they are.
