According to new data released by the U.S. Census Bureau, the country's population is getting older and more diverse.
The nation's median age jumped three years from 35 in 2000 to almost 38 in 2016.
That's because the baby-boom generation started turning 65 in 2011, causing an increase to the population of people over the age of 65.
While every state's median age increased in the past decade, Maine — with a median age of 44.6 — has the highest age in the country. Utah has the lowest median age with 30.8.
In regards to race and ethnic groups, the Census Bureau found that each group had seen growth. The populations of Asian people and people who identified as multiracial increased the most, growing by 3 percent.
The population that increased the least — non-Hispanic white people. While that group only grew by 5,000, they're still the second-largest population in the country with 198 million people.
The Census Bureau says that demographic had the lowest population increase because it's the only group where deaths are exceeding births.
Despite having the largest white population, California also had the largest populations of Hispanic people, Asians, American Indians, Alaskan Natives and multiracial people. Texas had the largest growth in almost all categories.
