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:
- 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%.
- 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.
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:
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.
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.”

Histomap: Visualizing the 4,000 Year History of Global Power
We examine an ambitious timeline that details the power of various civilizations going all the way back to 2,000 B.C.
Imagine creating a timeline of your country’s whole history stretching back to its inception.
It would be no small task, and simply weighing the relative importance of so many great people, technological achievements, and pivotal events would be a tiny miracle in itself.
While that seems like a challenge, imagine going a few steps further. Instead of a timeline for just one country, what about creating a graphical timeline showing the history of the entire world over a 4,000 year time period, all while having no access to computers or the internet?
An All-Encompassing Timeline?
Today’s infographic, created all the way back in 1931 by a man named John B. Sparks, maps the ebb and flow of global power going all the way back to 2,000 B.C. on one coherent timeline.

Histomap, published by Rand McNally in 1931, is an ambitious attempt at fitting a mountain of historical information onto a five-foot-long poster. The poster cost $1 at the time, which would equal approximately $18 when accounting for inflation.
Although the distribution of power is not quantitatively defined on the x-axis, it does provide a rare example of looking at historic civilizations in relative terms. While the Roman Empire takes up a lot of real estate during its Golden Age, for example, we still get a decent look at what was happening in other parts of the world during that period.
The visualization is also effective at showing the ascent and decline of various competing states, nations, and empires. Did Sparks see world history as a zero-sum exercise; a collection of nations battling one another for control over scarce territory and resources?
Crowning a world leader at certain points in history is relatively easy, but divvying up influence or power to everyone across 4,000 years requires some creativity, and likely some guesswork, as well. Some would argue that the lack of hard data makes it impossible to draw these types of conclusions (though there have been other more quantitative approaches.)
Another obvious criticism is that the measures of influence are skewed in favor of Western powers. China’s “seam”, for example, is suspiciously thin throughout the length of the timeline. Certainly, the creator’s biases and blind spots become more apparent in the information-abundant 21st century.
Lastly, Histomap refers to various cultural and racial groups using terms that may seem rather dated to today’s viewers.
The Legacy of Histomap
John Spark’s creation is an admirable attempt at making history more approachable and entertaining. Today, we have seemingly limitless access to information, but in the 1930s an all encompassing timeline of history would have been incredibly useful and groundbreaking. Indeed, the map’s publisher characterized the piece as a useful tool for examining the correlation between different empires during points in history.
Critiques aside, work like this paved the way for the production of modern data visualizations and charts that help people better understand the world around them today.

Which Country is the Cheapest for Starting a Business?
These maps show the most (and least) costly countries for starting a business by relative costs.
Which Country is the Cheapest for Starting A Business?
Starting a new business isn’t as simple as coming up with an idea.
In addition to the time investment needed to formulate and create a business, there’s often a hefty capital requirement. A new business usually requires paying different fees for licensing, permits, and approvals, and many governments also have minimum on-hand capital requirements.
And costs are relative. Though it might be more costly to start a business in some countries on paper, affordability also takes into account relative income.
These graphics from BusinessFinancing.co.uk use data from the World Bank’s Doing Business 2020 report to examine the startup cost for a small-to-medium-size LLC in the largest business cities across 190 countries.
The Cost of Starting a Business in Different Countries
From a pure cost perspective, the affordability of starting a business is extremely dependent on where you are located.
Some countries make the cost of business extremely low to encourage more economic activity. Others have high or nearly inaccessible fees to protect existing businesses, or to simply cash in on the entrepreneurial spirit.
|Country||Cost (2020 USD)||% of Monthly Income|
|Congo (Democratic Republic of the)||80||2.39|
|Trinidad and Tobago||115||0.1|
|Micronesia, Federated States of||231||0.82|
|Papua New Guinea||459||2.71|
|Central African Republic||529||14.55|
|United States of America||725||0.16|
|Bosnia and Herzegovina||833||1.93|
|Congo (Republic of the)||1229||25.46|
|Antigua and Barbuda||1271||-%|
|United Arab Emirates||7444||2.23|
At a glance, the cheapest regions for starting a business include Central Asia and Africa.
But the cheapest countries on the dollar for a new startup are Venezuela, Rwanda, and Slovenia. While the former does have fees that only total $0.21, both Rwanda and Slovenia have no fees for new businesses, though Slovenia does have a capital requirement of €7,500.
Expensive countries for new businesses are also spread across the world. There are some in Europe, including Italy at $4,876 and Austria at $2,475, as well as the Americas, including Suriname at $3,030 and Ecuador at $1,630.
The most expensive countries, however, are largely in the Middle East. They include #1 UAE at $7,444, #4 Qatar at $3,952, and #6 Lebanon at $2,855.
Which Country is the Most Affordable for Starting a Business?
Just as costs vary by country, so too does relative affordability.
Though some countries are cheaper than others for starting a business on the dollar, the picture changes when accounting for monthly income. When it comes to the cost of starting a business relative to monthly income, many developed countries take the cake.
Not including countries with missing data, the most affordable countries for starting a business include the UK, Denmark, and Ireland in Europe, South Korea in East Asia, and New Zealand in Oceania. Startup costs in each range from just 1%-2% of monthly income.
The picture is similar in the Americas, where Chile and Canada have the lowest relative fees at 2% and 5% of monthly income respectively. Even the U.S.—which has a decently high cost of $725 for starting a business—is relatively affordable at 16% of monthly income.
Some of the least affordable countries lie in the Middle-East and Central America. Haiti and Suriname have startup costs that are 1,403% and 1,114% of monthly income, while Yemen has affordability rates of 1,070%.
But the least affordable countries are in Africa. Many countries on the continent have startup costs that are more than 100% of monthly income, but the Republic of the Congo and the Central African Republic have affordability rates of 2,546% and 1,455% of monthly income, respectively.
Where is the best place to start a business? It can depend on the barrier to entry. But the biggest barrier takes time and ingenuity: finding the right idea at the right time.
