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.

RankCountryMedian AgeRegion
#1Japan47 yearsAsia
#2 (t)Germany45 yearsEurope
#2 (t)Italy45 yearsEurope
#4 (t)Greece44 yearsEurope
#4 (t)Bulgaria44 yearsEurope
#4 (t)Portugal44 yearsEurope

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.

RankCountryMedian AgeRegion
#1 (t)Chad14 yearsAfrica
#1 (t)Niger14 yearsAfrica
#3 (t)Afghanistan16 yearsMiddle East
#3 (t)Angola16 yearsAfrica
#3 (t)Burkina Faso16 yearsAfrica
#3 (t)Mali16 yearsAfrica
#3 (t)Somalia16 yearsAfrica
#3 (t)South Sudan16 yearsAfrica
#3 (t)Uganda16 yearsAfrica

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.

More Context on Aging

Ranking the World’s Most Populous Cities, Over 500 Years of History

This two-minute animation shows changes in the last 500 years of historical rankings for the world’s 10 most populous cities.

Animation: The Most Populous Cities, Over 500 Years

What do Beijing, Tokyo, Istanbul, London, and New York City all have in common?

Not only are they all world-class cities that still serve as global hubs of commerce, but these cities also share a relatively rare and important historical designation.

At specific points in history, each of these cities outranked all others on the planet in terms of population, granting them the exclusive title as the single most populated city globally.

Ranking the World’s Most Populous Cities

Today’s animation comes to us from John Burn-Murdoch with the Financial Times, and it visualizes cities ranked by population in a bar chart race over the course of a 500-year timeframe.

Beijing starts in the lead in the year 1500, with a population of 672,000:

RankCityPopulation in Year 1500
#1๐Ÿ‡จ๐Ÿ‡ณ Beijing672,000
#2๐Ÿ‡ฎ๐Ÿ‡ณ Vijayanagar500,000
#3๐Ÿ‡ช๐Ÿ‡ฌ Cairo400,000
#4๐Ÿ‡จ๐Ÿ‡ณ Hangzhou250,000
#5๐Ÿ‡ฎ๐Ÿ‡ท Tabriz250,000
#6๐Ÿ‡ฎ๐Ÿ‡ณ Gauda200,000
#7๐Ÿ‡น๐Ÿ‡ท Istanbul200,000
#8๐Ÿ‡ซ๐Ÿ‡ท Paris185,000
#9๐Ÿ‡จ๐Ÿ‡ณ Guangzhou150,000
#10๐Ÿ‡จ๐Ÿ‡ณ Nanjing147,000

In the 16th century, which is where the animation starts, cities in China and India were dominant in terms of population.

In China, the cities of Beijing, Hangzhou, Guangzhou, and Nanjing all made the top 10 list, while India itself held two of the most populous cities at the time, Vijayanagar and Gauda.

If the latter two names sound unfamiliar, that’s because they were key historical locations in the Vijayanagara and Bengal Empires respectively, but neither are the sites of modern-day cities.

The 1 Million Mark

For the first minute of animationโ€”and up until the late 18th centuryโ€”not a single city was able to eclipse the 1 million person mark.

However, thanks to the Industrial Revolution, the floodgates opened up. With more efficient agricultural practices, better sanitation, and other technological improvements, cities were able to support bigger populations.

Here’s a look at the biggest cities in the year 1895:

RankCityPopulation in Year 1895
#1๐Ÿ‡ฌ๐Ÿ‡ง London5,974,000
#2๐Ÿ‡บ๐Ÿ‡ธ New York3,712,000
#3๐Ÿ‡ซ๐Ÿ‡ท Paris3,086,000
#4๐Ÿ‡บ๐Ÿ‡ธ Chicago1,420,000
#5๐Ÿ‡ฏ๐Ÿ‡ต Tokyo1,335,000
#6๐Ÿ‡ท๐Ÿ‡บ St. Petersburg1,286,000
#7๐Ÿ‡ฌ๐Ÿ‡ง Manchester1,244,000
#8๐Ÿ‡ฌ๐Ÿ‡ง Birmingham1,074,000
#9๐Ÿ‡จ๐Ÿ‡ณ Beijing1,055,000
#10๐Ÿ‡ท๐Ÿ‡บ Moscow1,002,000

In the span of roughly a century, all of the world’s biggest cities were able to pass the 1 million mark, making it no longer a particularly exclusive milestone.

Modern City Populations

Finally, let’s look at the modern list of the top 10 most populous cities, and see how it compares to rankings from previous years:

RankCityPopulation in Year 2018
#1๐Ÿ‡ฏ๐Ÿ‡ต Tokyo38,194,000
#2๐Ÿ‡ฎ๐Ÿ‡ณ Delhi27,890,000
#3๐Ÿ‡จ๐Ÿ‡ณ Shanghai25,779,000
#4๐Ÿ‡จ๐Ÿ‡ณ Beijing22,674,000
#5๐Ÿ‡ฎ๐Ÿ‡ณ Mumbai22,120,000
#6๐Ÿ‡ง๐Ÿ‡ท Sao Paulo21,698,000
#7๐Ÿ‡ฒ๐Ÿ‡ฝ Mexico City21,520,000
#8๐Ÿ‡ช๐Ÿ‡ฌ Cairo19,850,000
#9๐Ÿ‡ง๐Ÿ‡ฉ Dhaka19,633,000
#10๐Ÿ‡บ๐Ÿ‡ธ New York City18,713,000

Interestingly, the modern list appears to be a blend of both previous rankings from the years 1500 and 1895, listed above.

In 2018, cities from China and India feature prominently, but New York City and Tokyo are also included. Meanwhile, Latin America has entered the fold with entries from Mexico and Brazil.

Demographics

How Different Generations Think About Investing

Each generation was shaped by unique circumstances, and these differences translate directly to the investing world as well.

How Different Generations Think About Investing

View the full-size version of the infographic by clicking here

Every generation thinks about investing a little differently.

This is partially due to the fact that each cohort finds itself on a distinct leg of life’s journey. While boomers focus on retirement, Gen Zers are thinking about education and careers. As a result, it’s not surprising to find that investment objectives can differ by age group.

However, there are other major reasons that contribute to each unique generational view. For example, what major world events shaped the mindset of each generation? Also, what role did culture play, and how do things like economic cycles factor in?

Finding Generational Discrepancies

Today’s infographic comes to us from Raconteur, and it showcases some of the most significant differences in how generations think about investing.

Let’s dive into some of the most interesting data:

1. Investment Outlook

The majority of millennials (66%) are confident about investment opportunities in the next 12 months. This drops down to 49% when boomers are asked the same question.

2. Volatility

How did different generations of investors react to recent bouts of volatility in the market?

  • 82% of millennials made changes to their portfolios
  • 69% of Gen X made changes
  • 47% of boomers made changes
  • 32% of the Silent Generation made changes

3. Knowledge and Ability

In terms of investment knowledge, 42% of millennials considered themselves to be experts in the field. On the same question, only 23% of boomers could say the same.

4. Financial Goals

Back when they were 27 years old, 45% of Gen Xers said their primary goal was to buy a home. Compare this to just 23% of millennials that consider a home to be their primary investment objective today.

5. Managing Investments

The majority of millennials (66%) saw the ability to manage all aspects of personal finance, including investments, in the same app as being important. Only 35% of boomers agreed.

Similarly, 67% of millennials saw recommendations made by artificial intelligence as being a basic part of any investment platform. Both Gen Xers and Baby Boomers were more hesitant, with 30% seeing computer-based recommendations as being integral.

6. Impact Investing

Millennials are twice as interested in ESG (environmental, social, and governance) investing, compared to their boomer counterparts. In fact, the majority of millennials (66%) choose funds according to ESG considerations.

Reasons for Not Investing

While generations may have varying investment philosophies, they seem a little more in sync when it comes to having reasons not to invest.

StatementMillennialsGen XBoomers
Recognize future outlook would be better if they start investing72%73%57%
Want to try out investing with a low money commitment35%31%25%
Afraid of losing everything42%29%28%
Too worried about current financial situation to think about future49%46%32%
Find information about investing difficult to understand63%59%55%
Don't have enough money to start investing55%59%56%

There are some similarities in the data here – for example, non-investors of all generations seem to have an equally tough time learning about investing, and similar proportions do not believe they have the funds to start investing.

On the flipside, it seems that millennials are more worried about their financial future, while simultaneously seeing a risk of “losing everything” stemming from investing.
