A study by researchers at UC Berkeley titled The Roots of Structural Racism has ranked US cities according to how segregated they are. Here's the list. Boston (OK, "Boston-Cambridge-Quincy, MA-NH") is 28th. Number one most-segregated city? NYC.
Here's a Guardian story about the study.
More than 80% of America’s large metropolitan areas were more racially segregated in 2019 than they were in 1990, the researchers found, even though explicit racial discrimination in housing has been outlawed for half a century. The levels of residential segregation appeared highest not in the American south, but in parts of the north-east and midwest: the most segregated metropolitan area in the US according to the study is New York City, followed by Chicago, Milwaukee and Detroit.
