Well, according to
@gang weeder's source:
1,815,144 black arrests were made in 2019
vs
4,729,290 white arrests
This means the 13/50 meme is probably closer to 13/40
~2 million into ~47 million is ~4.25% of blacks were arrested in 2019
~5 million into ~250 million is ~2% of whites were arrested in 2019
So, the New York Times statistic would be: The rate of criminality among African American communities is roughly 2 times the national average (4.25% vs 2%). There are several possible explanations for this discrepancy. HHH mentioned poverty being a factor. Police profiling may also be a factor. Genetics & culture may also be a factor.
