About 34 percent of the population of regional Houston communities lived in predominantly nonwhite suburbs in 2010. In comparison, residents living in truly diverse suburbs made up 13 percent of the area's population and those in predominantly white suburbs accounted for just 1 percent.

That's a stark contrast to 2000, when residents in predominantly nonwhite suburbs made up just 4 percent of the regional Houston communities' total population.

Those in diverse suburbs, on the other hand, accounted for 38 percent of the total in 2000; the 25 percentage-point drop in 2010 represents a unique decline of racial diversity in the Houston region.

The summarizing Houston report indicates more than 20 percent post-Katrina growth in the region's population, to nearly 6 million people.
