In the case of Black poverty in the US there are probably better places to look first than the issue of single parent households.<p>The main reason for the high poverty rates among the black population is pretty well understood. Firstly, the legacy of slavery and legally mandated segregation that amounts to 300 years of outright state sanctioned oppression. Secondly, historical and ongoing discrimination in employment and educational opportunities, discrimination over housing, discrimination over the availability of credit with good terms, and institutional discrimination in the criminal justice system and beyond.<p>After that you might then say something about how single parent households are typically less stable than two parent households, and the rate of single parent households is higher than the norm among black households. By this point though you might need to re-think the direction of causation.<p>The kind of analysis you put forward can easily start looking like its saying that poverty among black people is a moral failing of black people, rather than a moral failing of society. The latter is where most, but of course not all (black people are individuals with moral agency as well of course!), of the blame lies.<p>Example: The crack cocaine epidemic hit black communities quite hard, and although there are individual moral failing that lead to addiction and further societal breakdown (single parent households, highschool dropout rates etc...), the vulnerability of black populations due to historic systematic oppression played a large role in making those individual moral failings much more likely.
