Median Age of the Population in Every Country

The Median Age of the Population in Every Country

With a few notable exceptions, the world is rapidly aging.

Today’s infographic, which was shared by Bill Gates on Reddit, shows this incredible explosion in age and how different countries contrast with one another on this demographic metric.

While aging populations in Europe, North America, and Asia stand out on this type of visualization, it’s also important to look at the negative space. In both South America and Africa, populations are still quite young, with Africa getting younger and younger.

Note: The infographic is grouped based on U.N. regional classifications, and lumps Central America, the Caribbean, and South America as one demographic region.

The Oldest Countries

Which countries are the outliers in terms of global demographics?

Let’s start by taking a look at the oldest countries in terms of median age.

Rank	Country	Median Age	Region
#1	Japan	47 years	Asia
#2 (t)	Germany	45 years	Europe
#2 (t)	Italy	45 years	Europe
#4 (t)	Greece	44 years	Europe
#4 (t)	Bulgaria	44 years	Europe
#4 (t)	Portugal	44 years	Europe

Japan takes the cake for the oldest population and it’s joined by a host of European nations.

The following countries tied for the #7 spot, which is just off of the above list: Austria, Croatia, Latvia, Lithuania, Slovenia, Spain, and Bermuda. All of these places had median ages of 43 years, with Bermuda being the only non-European state of this group.

It’s worth noting that some smaller countries appear to be excluded from Gates’ infographic. As we showed on our last chart covering the subject of median age, which uses a different data set, the small city-state of Monaco (which has a population of just 39,000 people) actually has the highest median age in the world at 53.1 years.

The Youngest Countries

Now, let’s take a peek at the world’s youngest countries in terms of median age.

Rank	Country	Median Age	Region
#1 (t)	Chad	14 years	Africa
#1 (t)	Niger	14 years	Africa
#3 (t)	Afghanistan	16 years	Middle East
#3 (t)	Angola	16 years	Africa
#3 (t)	Burkina Faso	16 years	Africa
#3 (t)	Mali	16 years	Africa
#3 (t)	Somalia	16 years	Africa
#3 (t)	South Sudan	16 years	Africa
#3 (t)	Uganda	16 years	Africa

The youngest countries globally are Chad and Niger with a median population age of 14 years. Both are located in Sub-Saharan Africa.

The only non-African country is war-torn Afghanistan, where the median age is 16 years.

A variety of countries tied with a median age of 17 years old, which puts them just off of the above list. Those countries include: Benin, Burundi, Ethiopia, Madagascar, Malawi, Nigeria, Tanzania, Zambia, Yemen, and Timor-Leste.

Ranked: America’s Best-Value Public Universities in 2026

Key Takeaways

The University of Florida ranks first among America’s best-value public universities, combining a 91% graduation rate with median earnings of nearly $72,000 10 years after enrollment.
California, New York, and Florida account for 14 of the 20 schools on the list.
New Mexico Institute of Mining and Technology ranks fifth, with median earnings of $76,489, the highest of any school on the list.

This visualization ranks 20 U.S. public colleges and universities that pair below-median attendance costs with relatively strong student outcomes.

The data for this visualization comes from SmartAsset, which evaluated more than 500 public colleges and universities using data published in March 2026.

Cost of attendance was used as an eligibility filter rather than as part of the final composite score. SmartAsset calculated the median cost of attendance among qualifying public bachelor’s degree-granting institutions and only considered schools below that threshold.

Eligible institutions were then ranked using a composite score based on two outcomes: graduation rate and the median earnings of students 10 years after first enrollment.

Cost of attendance includes tuition, books, fees, and living expenses for full-time undergraduates.

Florida Leads the Ranking

The University of Florida ranks first overall, with a cost of attendance of $22,523, a 91% graduation rate, and median earnings of $71,588.

Rank	School	Cost of Attendance	Median Earnings (mid-career)	Graduation Rate
1	University of Florida	$22,523	$71,588	91%
2	Purdue University	$24,591	$72,424	83%
3	Baruch College	$14,170	$75,971	72%
4	Cal Poly Pomona	$23,955	$71,902	68%
5	New Mexico Institute of Mining and Technology	$24,967	$76,489	57%
6	Iowa State University	$24,018	$63,386	75%
7	California State University-Long Beach	$22,679	$64,403	69%
8	Florida International University	$21,462	$60,249	74%
9	California State University-Fullerton	$18,269	$62,951	70%
10	University of Central Florida	$23,133	$58,308	77%
11	University of South Florida	$22,859	$57,743	76%
12	University of Wisconsin-La Crosse	$19,593	$60,378	71%
13	Farmingdale State College	$18,966	$69,781	55%
14	Sonoma State University	$24,648	$65,986	59%
15	North Dakota State University	$23,716	$62,203	64%
16	City College of New York	$14,403	$66,039	56%
17	University of North Carolina at Charlotte	$23,010	$57,289	68%
18	California State University-East Bay	$22,850	$71,401	47%
19	SUNY Polytechnic Institute	$23,741	$64,355	57%
20	CUNY Hunter College	$13,905	$63,163	59%

Florida International University places eighth, followed by the University of Central Florida at 10th and the University of South Florida at 11th.

Part of Florida’s success in higher education stems from how the state structures and funds its public university system. Florida has long emphasized centralized oversight and relatively low tuition, particularly for in-state students.

New York Schools Pair Low Costs With Strong Earnings

Several New York institutions stand out for pairing low attendance costs with relatively strong earnings.

Baruch College, ranked third overall, has an attendance cost of just $14,170 while posting median earnings of $75,971. City College of New York and Hunter College show a similar pattern, with attendance costs close to $14,000.

California is also well represented, with five universities in the ranking. Cal Poly Pomona leads the state at fourth overall, combining a roughly $24,000 cost of attendance with median earnings of $71,902.

The broader California State University system accounts for several of the state’s entries, including Long Beach and Fullerton. These schools have graduation rates below the leaders at the top of the list, but relatively high earnings help strengthen their composite scores.

The ranking also shows why “best value” does not simply mean “cheapest.”

New Mexico Institute of Mining and Technology, for example, ranks fifth despite a 57% graduation rate. Its median earnings reach $76,489, the highest of any school on the list.

The Best and Worst Months to Book a Hotel in U.S. Cities

Key Takeaways

Hotel rates can vary dramatically by season, with New York showing a 103% swing between its cheapest and most expensive months.
Phoenix hotels are cheapest in August at $96 per night, compared with $246 in February and March.
Los Angeles has the smallest seasonal swing among the 20 cities shown, at just 14%.

If you’ve booked a hotel lately, you know that it’s a game of roulette.

One month it seems like you get a screaming deal, but then the next time you book, prices have mysteriously skyrocketed. Is it seasonal or is that by chance?

This visualization helps explain some of that variance by breaking down the best and worst months to book a hotel in U.S. cities.

The data and visualization both come from business travel company Engine, which put together a proprietary dataset on hotel prices by month for 50 U.S. cities using 129 million data points.

Highs and Lows of Hotel Prices by U.S. City

The table below summarizes the cheapest and most expensive months for the 20 cities shown above, along with each city’s median nightly rate and seasonal price swing.

For readers looking beyond these major markets, the complete dataset for all 50 cities appears at the bottom of this post.

City	Cheapest Month	Median Rate	Most Expensive Month	Swing
New York	Jan: $196	$335	Dec: $541	103%
Phoenix	Aug: $96	$159	Feb/Mar: $246	94%
Boston	Jan: $166	$331	Oct: $458	88%
Miami	Sep: $128	$179	Feb: $267	78%
San Diego	Dec: $156	$195	Jul: $292	70%
Chicago	Jan: $127	$274	Jun: $319	70%
New Orleans	Aug: $124	$165	Feb: $231	65%
Denver	Jan/Dec: $121	$169	Jun: $221	59%
Nashville	Jan: $136	$195	Oct: $243	55%
Washington, D.C.	Aug: $179	$287	May: $317	48%
Austin	Aug: $134	$164	Oct: $209	46%
Houston	Dec: $114	$135	Mar: $174	44%
San Francisco	Dec: $129	$166	Mar: $197	41%
Orlando	Aug/Sep: $101	$129	Feb: $150	38%
Minneapolis	Dec: $111	$137	Jul: $156	33%
Las Vegas	Jun: $132	$154	Oct: $180	31%
Atlanta	Dec: $120	$150	Jul: $160	27%
Dallas–Fort Worth	Dec: $112	$125	Jun: $139	22%
San Antonio	Jan: $99	$117	Mar/Jul: $124	21%
Los Angeles	Jan: $157	$169	Oct: $181	14%

The swing percentage is calculated as the priciest month minus the least expensive month, divided by the median price.

Cities With the Biggest Price Swings

The three cities with the biggest seasonal price swings in the dataset are New York (103%), Phoenix (94%), and Boston (88%).

The Big Apple has the most interesting contrast here, especially as the most visited city in the country. In December, it costs a high of $541 to book a hotel, but in January, after Christmas and New Year’s celebrations are over, that drops to a low of $196.

Similarly, January is the cheapest time to go to Boston ($166), with its priciest month being October ($458).

Phoenix shows the opposite pattern because of how hot the desert is in summer. Hotel prices plummet to $96 per night in August, but during the winter months of February and March, hotel prices peak at $246.

Cities That Have the Least Variance

But not all U.S. cities have intense seasonal variance. For these U.S. cities, there is no real best or worst month to book a hotel.

Los Angeles, with year-round good weather, is the clearest example in the dataset, with just 14% variance in hotel prices. The cheapest month for a hotel is January ($157), but it only costs $24 more per night to book in the most expensive month, October ($181).

Two cities in Texas, San Antonio and Dallas-Fort Worth, also show little variance by month in hotel prices, at 21% and 22%, respectively.
