Mapped: Each Region’s Median Age Since 1950

Over the last 70 years, the global population has gotten older. Since 1950, the worldwide median age has gone from 25 years to 33 years.

Yet, despite an overall increase globally, not all regions have aged at the same rate. For instance, Europe’s median age has grown by 14 years, while Africa’s has only increased by 1 year.

Today’s animated map uses data from the UN Population Index to highlight the changes in median age over the last 70 years, and to visualize the differences between each region. We also explain why some regions skew older than others.

Factors that Affect a Region’s Median Age

Before diving into the numbers, it’s important to understand the key factors that influence a region’s median age:

  1. Fertility Rate
    The average number of children that women give birth to in their reproductive years. The higher the fertility rate, the younger a population skews. Since 1950, the global fertility rate has dropped by 50%.
  2. Mortality Rate
    The number of deaths in a particular region, usually associated with a certain demographic or period in time. For example, global child mortality (children who have died under five years of age) has been on the decline, which has contributed to an increase in the average life expectancy across the globe.
  3. Migration
    International migration may lower a region’s population since migrants are usually younger or working age. In 2019, there were 272 million migrants globally.

The Change in Median Age

As mentioned, not all regions are created equal. Here’s how much the median age has changed in each region since 1950:

The Highs

Regions that have seen the most growth and generally skew older are Latin America, followed by Europe and Asia.

Interestingly, Asia’s notable increase is largely influenced by Japan, which has the oldest population on the planet. The country has seen a significant increase in median age since 1950—it’s gone from 22 to 48 years in 2020. This can be explained by its considerably low fertility rate, which is 1.4 births per woman—that’s less than half the global average.

But why is Japan’s fertility rate so low? There are more women in the workforce than ever before, and they are too busy to take on the burden of running a household. Yet, while women are more prosperous than ever, the workforce in general has taken a hit.

Japan’s recession in the early 1990s led to an increase in temporary jobs, which has had lasting effects on the region’s workforce—in 2019, about 1 in 5 men were working contract jobs with little stability or job growth.

The Lows

In contrast to Asia’s growth, Africa has seen the lowest increase in median age. The region’s population skews young, with over 60% of its population under the age of 25.

Africa’s young population can be explained by its high birth rate of 4.4 births per woman. It also has a relatively low life expectancy, at 65 years for women and 61 years for men. To put things into perspective, the average life expectancy across the globe is 75 years for women and 70 years for men.

Another trend worth noting is Oceania’s relatively small growth. It’s interesting because the region’s fertility rate is almost on par with the global average, at 2.4 births per woman, and the average life expectancy doesn’t differ much from the norm either.

The most likely reason for Oceania’s stagnant growth in median age is its high proportion of migrants. In 2019, the country had 8.9 million international migrants, which is 21% of its overall population. In contrast, migrants only make up 10% of North America’s population.

Unique Challenges for Every Region

Age composition has significant impacts on a region’s labor force, health services, and economic productivity.

Regions with a relatively high median age face several challenges such as shrinking workforce, higher taxes, and increasing healthcare costs. On the other end of the spectrum, regions with a younger population face increased demand for educational services and a lack of employment opportunities.

As our population worldwide continues to grow and age, it’s important to bring attention to issues that impact our global community. World Population Day on July 11, 2020, was established by the UN to try and solve worldwide population issues.

“The 2030 Agenda for Sustainable Development is the world’s blueprint for a better future for all on a healthy planet. On World Population Day, we recognize that this mission is closely interrelated with demographic trends including population growth, aging, migration, and urbanization.”

Timeline: A Historical Look at Every Mission to Mars

Within our Solar System, Mars is one of the most similar planets to Earth—both have rocky landscapes, solid outer crusts, and cores made of molten rock.

Because of its similarities to Earth and proximity, humanity has been fascinated by Mars for centuries. In fact, it’s one of the most explored objects in our Solar System.

But just how many missions to Mars have we embarked on, and which of these journeys have been successful? This graphic by Jonathan Letourneau shows a timeline of every mission to Mars since 1960 using NASA’s historical data.

A Timeline of Mars Explorations

According to a historical log from NASA, there have been 48 missions to Mars over the last 60 years. Here’s a breakdown of each mission, and whether or not they were successful:

The first mission to Mars was attempted by the Soviets in 1960, with the launch of Korabl 4, also known as Mars 1960A.

As the table above shows, the voyage was unsuccessful. The spacecraft made it 120 km into the air, but its third-stage pumps didn’t generate enough momentum for it to stay in Earth’s orbit.

For the next few years, several more unsuccessful Mars missions were attempted by the USSR and then NASA. Then, in 1964, history was made when NASA launched the Mariner 4 and completed the first-ever successful trip to Mars.

The Mariner 4 didn’t actually land on the planet, but the spacecraft flew by Mars and was able to capture photos, which gave us an up-close glimpse at the planet’s rocky surface.

Then on July 20, 1976, NASA made history again when its spacecraft called Viking 1 touched down on Mars’ surface, making it the first space agency to complete a successful Mars landing. Viking 1 captured panoramic images of the planet’s terrain, and also enabled scientists to monitor the planet’s weather.

Vacation to Mars, Anyone?

To date, all Mars landings have been done without crews, but NASA is planning to send humans to Mars by the late 2030s.

And it’s not just government agencies that are planning missions to Mars—a number of private companies are getting involved, too. Elon Musk’s aerospace company SpaceX has a long-term plan to build an entire city on Mars.

Two other aerospace startups, Impulse and Relativity, also announced an unmanned joint mission to Mars in July 2022, with hopes it could be ready as soon as 2024.

As more players are added to the mix, the pressure is on to be the first company or agency to truly make it to Mars. If (or when) we reach that point, what’s next is anyone’s guess.

Brand Loyalty is Declining for Most Luxury Automakers

Brand loyalty has declined for most luxury automakers, but three brands—Tesla, Maserati, and Genesis—appear to have bucked the trend.

Brand Loyalty is Declining for Most Luxury Automakers

New research conducted by S&P Global Mobility has found that brand loyalty—measured as the percentage of buyers that go back to the same brand for their next vehicle—is falling across the luxury segment.

In this infographic, we’ve visualized the results of this research, which spans from January 2020 to April 2022.

Brand Loyalty Losers

The following brands have all experienced a drop in brand loyalty over the time period.

For additional context, we’ve also included each brand’s score in the J.D. Power 2022 Initial Quality Study. This is measured based on the number of problems experienced per 100 vehicles (PP100) in the first 90 days of ownership.

BrandPercentage Point Change
in Brand Loyalty
PP100
🇬🇧 Land Rover-9.2193
🇩🇪 Porsche-8.5200
🇺🇸 Lincoln-7.9167
🇩🇪 Audi-7.3239
🇩🇪 Mercedes-Benz-7.0189
🇮🇹 Alfa Romeo-6.6211
🇺🇸 Cadillac-6.4163
🇸🇪 Volvo-5.3256
🇯🇵 Infiniti-5.2204
🇬🇧 Jaguar-5.1210
🇯🇵 Lexus-4.8157
Luxury average-4.5199
🇯🇵 Acura-2.7192
🇩🇪 BMW-2.3165

Land Rover experienced the biggest drop in loyalty, despite a better than average PP100 rating. One potential reason is timing⁠—the brand’s premier model, the Range Rover, has been in its fourth generation since 2012. The SUV has become relatively dated, though a new fifth generation was recently revealed for the 2022 model year.

Two Volkswagen Group brands, Audi and Porsche, also fared poorly in terms of loyalty. This is somewhat surprising, as both brands offer a portfolio of both gasoline and electric models. Many competitors, such as Acura, Lexus, and Maserati, have yet to release an EV.

Brand Loyalty Winners

Three brands have managed to buck the trend, as shown below.

BrandPercentage Point Change
in Brand Loyalty
PP100
Luxury average-4.5199
🇺🇸 Tesla+4.0226
🇮🇹 Maserati+4.3255
🇰🇷 Genesis+8.5156

We can draw parallels between Tesla and Apple, in that both have incredibly loyal followers.

For instance, between March 2021 to April 2022, 62% of buyers/households who returned to market and previously owned a Model 3 purchased a new Tesla. That’s an impressive statistic, especially when we consider Tesla’s history of build quality issues.

Maserati appears to be in the same boat. The Italian automaker has strengthened its brand loyalty by 4.3 percentage points, despite having the luxury segment’s worst PP100. Perhaps build quality matters less than we think.

Another Factor to Consider

Ongoing supply chain issues could also be contributing to wide-spread declines in loyalty. Rather than waiting several months (or in the case of EVs, years), buyers may switch to a different brand that has cars in stock.

We are still monitoring it week to week, but up to now basically worldwide, we had no issues running production.
– Joerg Burzer, Mercedes-Benz

Many automakers have reported that their supply issues are diminishing, though new economic challenges have risen. For example, surging inflation has pushed the price of a new car to record highs. Combined with rising interest rates (cost of borrowing), this could negatively impact the demand for new cars.
