See the median age in every US state. Only one state has gotten younger

Americans are growing up.

That is, according to last year’s official census data, the median age for US residents is 38.2 years, up from 2010’s 37.2 years. So on average, we’re a whole year older than we were almost a decade ago.

Maine comes in as the oldest state in the nation, population-wise, with a median age of 45 years. That makes the state’s residents two years older on average than they were in 2010.

Utah is the youngest, with the median resident of the Beehive State measuring up at 31 years of age.

North Dakota was the only state to decrease in median age, from 37.0 years in 2010 to 35.2 in 2018.

“This aging is driven in large part by [boomers] crossing over the 65-year-old mark. Now, half of the U.S. population is over the (median) age of 38.2,” Census Chief of Population Estimates Luke Rogers said in a press release.

Of the nation’s 3,142 counties, the populations of 2,566 — or 81.7% — had a higher median age in 2018 than they did in 2010. Sumter County, Florida, had the highest median age (at 67.8) and Madison County, Idaho, had the lowest median age (at 23.2).

About 10,000 boomers will reach 65 every day from now until 2030, but millennials are predicted to outnumber them this year when they reach 73 million in numbers and boomers drop to 72 million.

As medicine and technology continue to advance, it’s likely that the country will continue to see a rise in median age.

Let’s hope the nation’s retirement and assisted-living communities feel prepared to accommodate the increasing aging population.
