M: I can give you an example. Recently, a New York Times' article describes the town of Selinsgrove in Pennsylvania. You see, in the last ten years, things have barely changed in that town. The population has dropped by one from 5,384 to 5,383, and the town remains virtually 100% white. The article thus concludes that many portions of the country remain like Selinsgrove virtually unchanged on this march towards diversity.
W: So regions vary in terms of the degree and types of diversity.
M: That's correct. Let's see, there are 3 types of diversity in the U.S. and they differ from region to region.
W: Could you elaborate on that?
M: OK. The first is the racial diversity. States with the most racially diverse populations stand and start contrast to those with the least racially diverse populations.Umm, let's look at two states, California and Maine. From 1990 to 2000, California's Caucasian population, mainly non-Hispanic whites declined from 57% to 48%. By 2025 as it is predicted, that figure will drop to just 34%, which indicates a future change in a racial composition of California. On the contrary, Maine's Caucasian population was 98% of its total population to around the 1990s. And by 2025, Maine's population will still be 97% Caucasian, which means virtually no change in Maine's racial diversity over the next 20 or so years.
