The most diverse city in the United States is Gaithersburg, Maryland, while the least ethno-racially diverse place is Laredo, Texas.

In fact, four Maryland cities — including Gaithersburg, Germantown, Silver Spring and Rockville, all in Montgomery County, right outside of Washington, D.C. —  are in the top five when it comes to diversity in small U.S. cities.

Laredo, Texas, has the highest concentration of Hispanics in the country, at 95.2 percent.

The whitest city is Mount Pleasant, South Carolina, at 90.6 percent, while Detroit, Michigan, has the highest concentration of blacks at 79.1 percent. Honolulu, Hawaii, is the city with the highest clustering of Asians, at 52.1 percent.

The personal finance website WalletHub analyzed 313 of the most populated cities in the nation, using three main markers: racial and ethnic diversity, language diversity, and U.S. region of birth diversity.

The highest concentration of English speakers is in Springfield, Missouri (96.4 percent) and the highest concentration of Spanish speakers is in Miami, Florida (69.3 percent).

It’s no secret America is becoming a more colorful place.

From 2000 to 2013, minorities became the majority in 78 U.S. counties, with many of those demographic shifts occurring in California, the South, and along the East Coast, according an analysis conducted by the Pew Research Center.

U.S. Census Bureau data suggests minorities will become the majority in the United States within a generation. More than half of the children under five in the U.S. — 50.2 percent — are minorities. At the same time, deaths among white people are outpacing their births, according to the data from July 2014.

The overall population of the United States includes 197.9 million non-Hispanic white people, 55.4 million Hispanic people, 45.7 million black people, 20.3 million Asian people, 6.5 million American Indians and 1.5 million Hawaiians and other Pacific islanders.
