Thomas Young shares a Brookings-style listicle that ranks the ten states diversifying the fastest. More specifically, the list ranks "the 10 states that stand out when looking at the difference in share of the people of color aged 19 and younger compared to those aged 65 and older."

Before listing the ten fastest diversifying states, Young notes that "Hawaii and the District of Columbia already have the highest shares of people of color (77 percent and 64 percent, respectively), and given that those shares are already so high, their changes won’t be as drastic as other places."

Arizona tops the list, followed by Nevada and New Mexico. Arizona's "generational diversity gap" is reported at 40.72 percent, with 59 percent of people of color under the age of 19 and 18 percent of people of color over the age of 65.

Earlier in February, the Brookings Institution released an interactive map showing the country's evolving diversity, based on data from the U.S. Census and the Diversity Explosion: How New Racial Demographics are Remaking America book, authored by William Frey and released in November 2014.
