Mapped: The Median Age of the Population on Every Continent
Earlier this week, the Bill and Melinda Gates Foundation published their annual letter that highlights the surprises they saw in 2018, as well as the philanthropic opportunities they’ve identified for the future.
Among many other compelling facts and stories, the letter pointed out one surprise that we thought was of particular interest: the median age of the African continent is just 18 years old.
Median Ages, by Continent
Today’s chart was inspired by the Gates’ letter, and it showcases the median age of each continent along with other pertinent data points.
|North America||35 years|
|South America||31 years|
What’s interesting here is not only Africa’s median age, but also that the median age for each other continent is at least 13 years older. In other words, this means Africa is a real demographic outlier.
In their letter, Bill and Melinda Gates drop one additional fact that helps crystallize this even further: by 2100, it’s projected that nearly half of the world’s children aged 0-4 years old will be in Sub-Saharan Africa.
Median Ages, by Country
The difference in median age between Africa and Europe is quite astonishing, but the gap gets even wider when we look at individual countries.
For example, Monaco is the country with the oldest population in the world with a median age of 53.1 years – but this is roughly 3.5x higher than the median age of Niger, where it is just 15.4 years.
Here are the five oldest countries, along with the five youngest:
|Rank||Country||Median Age (Youngest)||Rank||Country||Median Age (Oldest)|
|#1||Niger||15.4 years||#1||Monaco||53.1 years|
|#2||Mali||15.8 years||#2||Japan||47.3 years|
|#3||Uganda||15.8 years||#3||Germany||47.1 years|
|#4||Angola||15.9 years||#4||Italy||45.5 years|
|#5||Zambia||16.8 years||#5||Slovenia||44.5 years|
While it is not surprising that Monaco – a small and wealthy city-state that sits on the French Riviera with a population of just 40,000 people – is the oldest country in the world, it seems that age could be a real challenge for the major economies that also make this list.
Germany, Italy, and Japan have some of the largest economies in the world with a combined nominal GDP equal to 12.2% of global output. At the same time, they are also three of the oldest countries right now, and they are each projected to hit a median age of 50 years or higher by the year 2050.
On the other end of the spectrum, there are more than 30 countries that have median ages under 20 years, with most of them existing in Africa or the Middle East. One exception to this is Timor-Leste, a small country bordering Indonesia, which has a median age of 18.9 years.
A Visual History of the Largest Companies by Market Cap (1999-Today)
See how the world’s largest companies have changed over time, and how this helps tell a broader story about what the market is thinking.
A Visual History of the Largest Companies by Market Cap
The macro narrative that underlies the market is constantly under revision.
While this is partially a function of shifts in investor sentiment, it’s also driven by game-changing events as well as much more structural market forces.
For example, how does the macro narrative change after a commodity price crash? What about when the unprecedented scale of technology is truly understood by the market?
An Evolving Narrative
In this week’s chart, we look at how the big picture narrative has changed over time by using a very simple approach.
We have visualized the market capitalizations of the 10 largest public companies in the world over five-year intervals from 1999 until today, and it gives us a series of snapshots of what the market was “thinking” during these specific periods.
Not only is it evident as certain industries rise to prominence, but there are also some interesting individual stories to follow. We can see iconic companies – such as Apple – ascend into the public consciousness, while others fall off the radar completely.
|Year||Description||Top Company||Who Dominates Top 10?|
|1999||Dotcom Bubble||Microsoft ($583B)||Five tech companies in the mix|
|2004||Post-Bubble||GE ($319B)||Diverse mix of companies by industry|
|2009||Financial Crisis||PetroChina ($367B)||Six non-U.S. companies make list|
|2014||$100 Oil||Apple ($560B)||Last year for oil companies, tech starts ascending|
|2019||Big Tech Era||Microsoft ($1,050B)||Seven companies are tech|
The composition of the top 10 changes in each of the snapshots above, and this simple approach helps capture the market narrative for each timeframe.
During the Dotcom Bubble, you can see that half of the list was dominated by tech companies. This was short-lived, and the years 2004, 2009, and 2014 have much more diverse lists.
You can also see the impact of the financial crisis on U.S. company valuations. In 2009, there is an equal distribution of Chinese and American companies. Royal Dutch Shell (UK/Netherlands) and Petrobras (Brazil) help round out the top 10.
Finally, over the last five years, you can see the impact of lower oil prices and the growing scale of tech. Back in 2014, Exxon Mobil was the second largest company in the world by a solid margin, but today it’s been displaced by companies like Facebook, Amazon, Tencent, and Alibaba.
The Big Tech Era
Here is the current top 10 list of the world’s largest companies by market cap:
|#1||🇺🇸 Microsoft||Tech||$1,050 billion|
|#2||🇺🇸 Amazon||Tech||$943 billion|
|#3||🇺🇸 Apple||Tech||$920 billion|
|#4||🇺🇸 Alphabet||Tech||$778 billion|
|#6||🇺🇸 Berkshire Hathaway||Diversified||$507 billion|
|#7||🇨🇳 Alibaba||Tech||$435 billion|
|#8||🇨🇳 Tencent||Tech||$431 billion|
|#9||🇺🇸 Visa||Financial||$379 billion|
|#10||🇺🇸 Johnson & Johnson||Consumer Goods||$376 billion|
In total, the five biggest tech giants brought in a combined $801.5 billion in revenue last year, and $139 billion in net income.
The Staying Power of Microsoft
With a valuation today of just over $1 trillion, Microsoft is again the world’s largest company by market capitalization.
In this way, the above lists come full circle, since Microsoft was also the biggest company in 1999.
While the software giant experienced short periods where it did drop out of favor, Microsoft was the only company to make the list in our five snapshots above.
The 10 Breakthrough Technologies That Will Define 2019
Which innovations will dominate headlines in 2019? According to Bill Gates, watch for these 10 breakthrough technologies to change the world.
The 10 Breakthrough Technologies That Will Define 2019
Gone are the days of turning stones into spears. With the advent of new technologies, we’ve learned to develop tools that not only make living faster and easier every day, but also improve the future of humanity as a whole.
Today’s Chart of the Week draws from the MIT Technology Review, which features Bill Gates’ predictions for the top 10 breakthrough inventions that will capture headlines in 2019.
Top 10 Breakthrough Technologies
1. Gut Probe in a Pill
These swallowable devices can detect and potentially prevent diseases that cause malnutrition and stunted growth in millions of children worldwide.
2. Custom Cancer Vaccines
Personalized cancer vaccines, targeting only the cancerous cells and leave healthy cells alone, could help ensure faster recovery times and pose fewer risks to patients.
3. Meat-free Burgers
Plant-based and lab-grown food products will ideally alleviate the environmental impact of the livestock industry.
4. Smooth-talking AI assistants
The AI assistants of the future will have even more human-like conversations to personally engage customers. Companies would see measurable benefits, with just one breakthrough here garnering a 5% jump in productivity.
5. Sanitation without sewers
Improperly drained sewage causes death in one out of every nine children. Sanitation that doesn’t require sewers would not only prevent exposure diseases but also help turn waste into useful products like fertilizer.
6. ECG on your wrist
While most medical ECGS have up to 12 nodes to detect abnormalities, today’s wearables typically have only one. An ECG on the wrist would help reduce the risk of heart disease by monitoring changes and patterns in daily life.
7. Robot Dexterity
Advancements in robotics will enable the natural dexterity required to complete a greater range of tasks, such as helping an ailing loved one out of bed, doing the laundry, or building toys.
8. Predicting Preemies
Premature births are the leading cause of death for children under five years old. Tests to detect the possibility of a premature birth could be available in doctors’ offices in as little as five years.
9. Carbon Dioxide Catcher
Carbon dioxide catchers filter out CO₂ from the air and capture it for other uses. These include synthetic fuel creation, CO₂ for soft drinks, and plant growth in greenhouses.
10. New-wave Nuclear Power
Traditional nuclear reactors produce ~1,000 megawatts (MW), while these proposed mini-reactors would produce tens of megawatts ─ making them safer, more stable, and more financially viable for potential users.
A Vision for a Better Future
The biggest takeaway?
Seven of the 10 breakthrough technologies stem from the healthtech sector.
While several inventions on this list are years away from becoming a reality, they continue to embody the vision and passion that humans share to create and explore.
