As the United States has become more diverse, it has also become more racially segregated, according to a new nationwide analysis from researchers at the University of California, Berkeley.

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.
