Blacks seem to do a little better in more conservative regions.
Using GSS data for the nine U.S. regions, I calculated the Pearson correlations between: 1) the percent of black men who are married, 2) the mean level of church attendance (for all races), and 3) the mean level of political conservatism (for all races).
All correlations are positive and very strong: percent married/church attendance, .84; and percent married/political conservatism, .66. (While we're at it, the correlation between attendance and conservatism across the nine regions is .89. Religiosity and conservatism are, empirically, practically the same thing.)
