Mapped: The Median Age in Every U.S. County
To see the high resolution version of this map, go here.
The United States is a vast place, and every region is markedly different.
Usually we look at these differences through lenses like geography, population density, preferences, wealth, and culture – but age is another interesting one to think about, and age is a significant factor in predicting future economic health and growth for almost any society.
The Age Factor
As the French philosopher Auguste Comte wrote, “Demography is destiny”.
If you know a person’s age, you’re usually able to guess other things about them. For example, younger people are usually more motivated and inclined to launch careers, start families, and seek economic security. Not all young people are this way of course – but in aggregate, this is generally true.
Today’s map comes to us from Reddit user /r/JFBoyy and it charts median age by every U.S. county, parish, borough, and Census Area.
Counties by Age
Which states and counties stand out on the map?
Utah is an interesting place to start – it’s the youngest state with a median age of 29.9, and this is extremely clear when looking at the county level. The state has only one county (Daggett) with a median age range above 35-44 years.
Florida and Maine are two other states that stand out. Florida is the stereotypical “old” state, and there is some truth to that based on the numbers. It’s the only state that has a county (Sumter) with a median age range over 65 years. Meanwhile, Maine has only five counties that are not “old” counties – and the majority of counties have median ages that fall in the 45-54 range.
The Midwest and Southeast seem to have a higher distribution of counties with median ages in the “middle ground” 35-44 median age range. Alabama has 67 counties, and all but five of them are in that bracket.
Meanwhile, the West seems to have an interesting dichotomy in many of its states. Washington State, for example, has many counties with old populations (San Juan, Jefferson, and others) but also counties with younger populations (Whitman, Yakima, Kittitas).
Idaho is the most potent example of this tendency: all of the old people seem to live in the north of the state, and all of the young people in the south.
A Look to the Future
Here is how median age projects out to 2040, but on a state level.
Overall the national median age is projected to go from 37.7 to 39 years.
Interestingly, while aging in the United States is expected to cause some demographic issues in the long run, the country’s challenges pale in comparison to other rapidly-aging countries in the Western world.
Charted: The World’s Biggest Oil Producers
Just three countries—the U.S., Saudi Arabia and Russia—make up the lion’s share of global oil supply. Here are the biggest oil producers in 2022.
Charted: The World’s Biggest Oil Producers in 2022
In 2022 oil prices peaked at more than $100 per barrel, hitting an eight-year high, after a full year of turmoil in the energy markets in the wake of the Russian invasion of Ukraine.
Oil companies doubled their profits and the economies of the biggest oil producers in the world got a major boost.
But which countries are responsible for most of the world’s oil supply? Using data from the Statistical Review of World Energy by the Energy Institute, we’ve visualized and ranked the world’s biggest oil producers.
Ranked: Oil Production By Country, in 2022
The U.S. has been the world’s biggest oil producer since 2018 and continued its dominance in 2022 by producing close to 18 million barrels per day (B/D). This accounted for nearly one-fifth of the world’s oil supply.
Almost three-fourths of the country’s oil production is centered around five states: Texas, New Mexico, North Dakota, Alaska, and Colorado.
We rank the other major oil producers in the world below.

|54||Other Asia Pacific||177||-10.6%||0.2%|

Behind America’s considerable lead in oil production, Saudi Arabia (ranked 2nd) produced 12 million B/D, accounting for about 13% of global supply.
Russia came in third with 11 million B/D in 2022. Together, these top three oil producing behemoths, along with Canada (4th) and Iraq (5th), make up more than half of the entire world’s oil supply.
Meanwhile, the top 10 oil producers, including those ranked 6th to 10th—China, UAE, Iran, Brazil, and Kuwait—are responsible for more than 70% of the world’s oil production.
Notably, all top 10 oil giants increased their production between 2021–2022, and as a result, global output rose 4.2% year-on-year.
Major Oil Producing Regions in 2022
The Middle East accounts for one-third of global oil production and North America makes up almost another one-third of production. The Commonwealth of Independent States—an organization of post-Soviet Union countries—is another major regional producer of oil, with a 15% share of world production.

What’s starkly apparent in the data however is Europe’s declining share of oil production, now at 3% of the world’s supply. In the last 20 years the EU’s oil output has dropped by more than 50% due to a variety of factors, including stricter environmental regulations and a shift to natural gas.
Another lens to look at regional production is through OPEC members, which control about 35% of the world’s oil output and about 70% of the world’s oil reserves.
When taking into account the group of 10 oil exporting countries OPEC has relationships with, known as OPEC+, the share of oil production increases to more than half of the world’s supply.
Oil’s Big Balancing Act
Since it’s the very lifeblood of the modern economy, the countries that control significant amounts of oil production also reap immense political and economic benefits. Entire regions have been catapulted into prosperity and wars have been fought over the control of the resource.
At the same time, the ongoing effort to pivot to renewable energy is pushing many major oil exporters to diversify their economies. A notable example is Saudi Arabia, whose sovereign wealth fund has invested in companies like Uber and WeWork.
However, the world still needs oil, as it supplies nearly one-third of global energy demand.
