Diversity changes in Maine and the rest of the USA


These Counties Are Getting More Diverse

Using historical data from The National Historical Geographic Information System (NHGIS) and the United States Census, created a “Diversity Index” to see which places in America have become the most racially diverse from 1970 to 2010. It’s been predicted that by 2050, the vast majority of Americans will be multiracial. In 2000, the U.S. Census Bureau reported that 6.8 million people identified as more than one race. 
That figure had increased to nearly 32%—9 million—in 2010. In some cities, this evolution may take some time, as many communities tend to self-segregate—even if they don’t mean to. But in others, the racial and ethnic makeup of the city that may have defined it a mere 30 years ago has completely changed, and will continue to do so. Using historical data from The National Historical Geographic Information System (NHGIS) and the United States Census, MooseRoots created a “Diversity Index” to see which cities in America have become the most racially diverse from 1970 to 2010. 
 To do so, they took the four race classifications from the census: White, Black or African-American, American Indian and Alaska Native, Asian and Pacific Islander, and Other Race. They didn’t include multi-racial individuals because the census only began tracking multi-racial demographics in 2000. MooseRoots deemed the most diverse places those where racial makeup approached an even distribution between the four classifications.
Looking at the map, it’s very clear that the Southeast has quickly become more diverse since 1970. The West, on the other hand, has seen less of a spike. This is probably due to the fact that many states in that region of the U.S. were relatively diverse to begin with in the ‘70s, so the increase in racial diversity was more gradual. 
 Here are the that have demographically diversified the most and least:

10. Franklin County
