Right, I agree with your statement. But the idea that was stated pertained to the correlation between low income and criminal conviction rates. So in this instance we see a disproportionately higher rate of criminal convictions for people of color in New York, but a significantly more equal conviction rate (racially) in Southern States. These two things suggest that the socioeconomic racial inequalities are worse in the North East than in the South East. We're not talking about general income disparities. Again, from what the commenter said, it would basically suggest that the racial proportionality (Black/White) of low income households is more equal in Southeastern states than Northeastern states.
