Though you make the good point that it's not the single important metric, I really feel that the relative proportion of coresidential black fathers is certainly one of the major important metrics on whether a child gets face time with their parent and feels that their father is part of their life. Other metrics are also important, however it is imperative when speaking about the relative upbringing within black vs non black families, to cite every used metric for both blacks and non blacks to draw the comparison. When the primary thesis is drawing a comparison between two populations, and even through a ton of discussion and elaboration, no actual statistical apples to apples comparisons between the two populations are drawn, it is hard to imagine that the argument is being had in good faith.

For this argument, you want to take a side by side table with black vs non black as the two columns, and various stats of interest across each row. The first rows can be the rates of cohabitation of father, rates of single motherhood, number of hours spent per week with children, etc. This table would be the starting point of the discussion. Picking stats from one of the columns and saying "this one's a big number!" doesn't help draw a relative comparison. With all due respect.
