Since blacks make up 50.4% of the Richmond population and whites only 39.8%, I wonder what the fatherless rate is for whites?
34.416 non-black. Not enough information to give the white specific rate.
Your population statistics may not match the statistics for numbers of families with kids(with or without fathers).
Assuming 50.4 percent of all families with kids in Richmond are black and 86 per cent of these black families have no fathers...then these black families represent 43.34 per cent of all families in Richmond that have no fathers in them. Since fatherlessness over all in Richmond is 60 per cent then the other 16.66 per cent is split between the 39.8 per cent of families with kids that were white and the other 9.8 per cent of other nationalities of families who have kids. If you add the whites and non black minorities together you have 49.6 and multiplying 16.66 per cent you get, out of the total number of non black minorities and white families who have kids in Richmond, 8.26 per cent who are fatherless.
So of the total populations of families in Richmond with kids ...43.34 percent are black and fatherless and 8.43 percent of the total amount are white/non black minority families who are fatherless. Giving an overall rate of 60 percent total fatherlessness of all the families in Richmond. (with a rate of 86 per cent amongst black families....that is using the numbers you provided.) I suspect though that using total population figures isn’t valid)
