As of 2010, the United States had a total resident population of almost 310 million with a median age of 37.2 years. The largest population group, however, was the 45-59 age bracket with a population of 22.7 million followed by the 50-59 group with 22.3 million. The smallest age bracket, unsurprisingly, was the 85 and older group with just 5.5 million.
The states with the youngest populations in 2010 based on median age were geographically dispersed. Utah was the youngest with a median age of 29.2 years, followed by Texas (33.6) and Alaska (33.8). East coast states took the top five slots for "oldest" states, all with a median age of at least 40. Maine beat out Vermont, West Virginia, New Hampshire and even Florida as the oldest state with a median age of 42.7 years.
The racial profile of the United States changed significantly in the decade from 2000 to 2010. In 2010, 65.8 percent of the population self-identified as White, down from 81 percent a decade earlier. In addition, for most of the decade the Hispanic population was the second largest racial group in the United States, making the black population the third largest racial group in the United States. For those who identify with two more races, the majority live on the West coast. In contrast, the population identifying with a single race is more highly concentrated in the midwest.
