Ferguson, Mo., stands out for the level of racial turbulence it has experienced this month. But as an economically lagging community that has undergone rapid demographic change in the last couple of decades, it’s not unusual at all.

An analysis performed for The Upshot by Andrew Beveridge, a sociology professor at Queens College, shows that there are 117 communities of 5,000 or more people in the United States that, like Ferguson, were over 50 percent white in 1990 and shifted to over 50 percent black in 2010.

Not all of them have the troubled racial history of Ferguson or its demographic mismatch between the population and the police, but they do resemble Ferguson in two ways: Most are suburban, and most are poorer than their overall metro area.

If you rank these communities according to the degree of change they have undergone, Ferguson comes out somewhere in the middle. It ranks 51st out of 117 in terms of the decline in the percentage of its population that is white (which was 73 percent in 1990, but 29 percent in 2010), and 38th if ranked by the growth in its black population (25 percent in 1990, 67 percent in 2010).
