You might have already heard, but for most people in and around the Houston area, this is still pretty big news. Houston is the most ethnically diverse megalopolis in the United States.

Smithsonian magazine has published an excellent article that you can read here. I also have a printer friendly version here. Of course no great article would be complete without a handy handout to help you understand and analyze the article, available here.
