The U.S. population is growing older and more racially and ethnically diverse. That's according to new data by the Census Bureau.
Between July 2016 and July 2017, non-Hispanic whites were the only racial group that didn't get any bigger. In fact, it decreased by 0.02 percent.
The Asian population had the largest growth, increasing by 3.1 percent. That group was followed by people of two or more races, which increased by 2.9 percent.
The U.S.' white population is still the largest. It's also the oldest — data showed it had the highest median age of all populations.
Bureau data also found that from 2010 to 2017, most U.S. counties got older. America's median age has grown from 37.2 to 38. A census official said that's because baby boomers are getting older and because "the birth rate has declined steadily over the last decade."
