It may I have been a bit earlier than that, I remember the story and the research behind it. HS graduation rates were higher as well. The comparison was that all immigrant groups to this country started as an isolated section of American society and thus had a greater cohesion of values leading to stronger society values like strength of family. Blacks fit into this trend if you counted post-reconstruction as their actual immigration into this society.
Immigrant groups would then fall in line with mainstream society except at that point, blacks got screwed by the Civil Rights Act and the Great Society.
“1950’s, the marriage rate for blacks was higher than whites”
Poor women were more likely to have a child out of wedlock and blacks tended to be poor. One of the arguments for Jim Crow was the illegitimacy rates in the black community where it was more accepted.
Totally inaccurate...research it
Black rate was forty times whites back then
Since then they have both gone up
