‘US News and World Report’ Reveals the Top 10 US States With the Least Racial Diversity

The U.S. Census Bureau published the 2020 Census in early August, revealing an increasingly diverse overall population within the United States — and, for the first time, a decline in people who identified solely as white. Although there has been a dramatic shift in U.S. demographics between 2010 and 2020, changes (or lack thereof) in the racial makeup were also very regional. 

U.S. News and World Report’s Kaia Hubbard compiled a list of the least racially diverse states in the U.S. while noting that producing these types of lists has become more of a challenge recently since “a growing number of people identify with more than one race in the U.S.”

“The white population remains the largest racial or ethnic group in the country, at 57.8% of the population, but that group has decreased from 63.7% in the last decade,” Hubbard said. “The multiracial population has increased from 9 million people to 33.8 million in the last 10 years — a 276% increase.”

In addition to general population figures, the U.S. News and World Report list also used data from the Census Bureau’s “diversity index,” a measurement recently created by the agency “which indicates the likelihood that two people within a population chosen at random will be from different race and ethnic groups.”
