The U.S. population is older now than it has been since record keeping began. The median age in the United States is 38.2 years, up from 36.9 years a decade ago, and from less than 30 in the 1970s.
This trend is the result of several factors – both long and short term. For one, Americans are now living longer than they have in past decades. Driven in part by improvements in health care, average life expectancy at birth in the U.S. is now about 77 years, five years longer than it was in the mid-1970s. More recently, falling birth rates and tightened restrictions on immigration – particularly during the COVID-19 pandemic – have accelerated the aging of the U.S. population.
As the country as a whole is skewing older, there are places that stand out for having especially young populations. Using data from the U.S. Census Bureau, 24/7 Wall St. identified the 50 U.S. cities – defined as places with at least 25,000 residents – with the youngest populations.
Among the places on this list, the median age of the population ranges from about 26 years to just 14. The cities on this list span the country, though Utah is home to eight, the most of any state.
Most of these cities are college towns, home to universities or colleges. These places include Blacksburg, Virginia; Chapel Hill, North Carolina; Ithaca, New York; and State College, Pennsylvania. In 30 of the cities on this list, over one-third of the population are enrolled in college, compared to less than 7% of the U.S. population.
Some other places on this list – including Jacksonville, North Carolina and Twentynine Palms, California – are home to military installations. Because Americans must be between the ages of 17 and 35 to enlist, military bases tend to have relatively young populations. (Here is a look at the states where the most Americans serve in the military.)
Several of these cities are also home to a relatively large number of families raising children. In over half a dozen cities on this list, more than 50% of households include children under age 18. These places include Eagle Mountain, Utah, a master-planned, family oriented community outside of Provo and nearby Saratoga Springs, Utah. (Here is a look at the best and worst states to raise a family.)

Methodology
To determine the cities with the lowest median ages, 24/7 Wall St. reviewed five-year estimates of median age from the U.S. Census Bureau’s 2020 American Community Survey.
We used census “place” geographies — a category that includes incorporated legal entities and census-designated statistical entities. We defined cities based on a population threshold — census places needed to have a population of at least 25,000 to be considered.
Cities were excluded if median age was not available in the 2020 ACS or if the sampling error associated with a city’s data was deemed too high.
The sampling error was defined as too high if the coefficient of variation — a statistical assessment of how reliable an estimate is — for a city’s median age was above 15% and greater than two standard deviations above the mean CV for all cities’ median ages. We similarly excluded cities that had a sampling error too high for their population, using the same definition.
Cities were ranked based on median age. To break ties, we used the share of the population that is 18 and younger.
Additional information on the share of the population that is currently enrolled in college, the share of the population that is 18 and younger, the share of the population that is 65 and older, and total population are also five-year estimates from the 2020 ACS.
Is Your Money Earning the Best Possible Rate? (Sponsor)
Let’s face it: If your money is just sitting in a checking account, you’re losing value every single day. With most checking accounts offering little to no interest, the cash you worked so hard to save is gradually being eroded by inflation.
However, by moving that money into a high-yield savings account, you can put your cash to work, growing steadily with little to no effort on your part. In just a few clicks, you can set up a high-yield savings account and start earning interest immediately.
There are plenty of reputable banks and online platforms that offer competitive rates, and many of them come with zero fees and no minimum balance requirements. Click here to see if you’re earning the best possible rate on your money!
