Animated Map: The Most Populous Cities in the World

In Africa Alone, 13 Cities Will Pass NYC in Size

The Chart of the Week is a weekly Visual Capitalist feature on Fridays.

If you look at a modern map of the world’s most populous cities, you’ll notice that they are quite evenly distributed around the globe.

Metropolises like Moscow, New York, Tokyo, Cairo, or Rio de Janeiro are spread apart with very different geographic and cultural settings, and practically every continent today can claim at least one of the world’s 20 most populous cities.

In the future, things will be very different, according to projections from the Global Cities Institute. In fact, over the next 80 years or so, some cities will literally 10x or 20x in size – turning into giant megacities that have comparable populations to entire countries like modern-day Germany, France, or the United Kingdom.

The most interesting part? None of these cities will be in the Americas, Europe, China, or Australia.

The Top Four Megacities of the Future

According to predictions from the Global Cities Institute, these will be the biggest cities in the world in 2100:

Lagos

Lagos is already one of the biggest metropolises in Africa, and we previously noted that it was one of the fastest growing cities in the world.

In fact, it’s growing so fast, that no one knows how big it actually is. The U.N estimated it had 11.2 million people in 2011, and the year after The New York Times said it had at least 21 million inhabitants. In any case, this Nigerian metropolis is growing like a weed, and the Global Cities Institute estimates that the city’s population will hit the 88.3 million mark by 2100 to make it the biggest city in the world.

The city is already a center of West African trade and finance – but Lagos has ambitious plans to up the ante even further. Right now, the city is building Eko Atlantic, a massive new residential and commercial development that is being pitched as the “Manhattan of Nigeria”. It’s just off of Victoria Island, and it is being built on reclaimed land with special measures in place to prevent flooding from global warming.

Kinshasa

When people think of the DRC, sprawling metropolises generally aren’t the first things that come to mind.

But Kinshasa, once the site of humble fishing villages, has already likely passed Paris as the largest French-speaking city in the world. And it’s getting bigger – by 2100, it’s projected to be the world’s second largest city overall.

How Kinshasa develops will certainly be interesting. As it stands, approximately 60% of the 17 million people living there by 2025 will be younger than 18 years old. How the city deals with education will be paramount to the city’s future progression.

Dar Es Salaam

Have you heard of Dar Es Salaam, the Tanzanian megacity that will hold 73.7 million inhabitants in 2100?

It’s not on a lot of people’s radars, but its population will explode 1,588% to become the third largest city in Africa, and in the world.

Interestingly, East Africa will be home to many of the world’s biggest cities in the future – and many will be seemingly popping up out of nowhere. Consider Blantyre City, Lilongwe, and Lusaka, for example. Most Westerners will not likely have heard of these places, but these centers in Malawi and Zambia will each hold over 35 million people.

Mumbai

Finally, the last city to round out the top four is Mumbai, which is already one of the world’s biggest megacities with over 20 million people.

As the entertainment capital of India, it will be interesting to see how Mumbai evolves – and how it ends up comparing to other Indian megacities like Delhi and Kolkata, which each will hold over 50 million residents themselves.

Historical Returns by Asset Class

Historical Returns by Asset Class (1985-2020)

Mirror, mirror, on the wall, is there one asset class to rule them all?

From stocks to bonds to alternatives, investors can choose from a wide variety of investment types. The choices can be overwhelming—leaving people to wonder if there’s one investment that consistently outperforms, or if there’s a predictable pattern of performance.

This graphic, which is inspired by and uses data from The Measure of a Plan, shows historical returns by asset class for the last 36 years.

Asset Class Returns by Year

This analysis includes assets of various types, geographies, and risk levels. It uses real total returns, meaning that they account for inflation and the reinvestment of dividends.

Here’s how the data breaks down, this time organized by asset class rather than year:

*Data for 2020 is as of October 31

The top-performing asset class so far in 2020 is gold, with a return more than four times that of second-place U.S. bonds. On the other hand, real estate investment trusts (REITs) have been the worst-performing investments. Needless to say, economic shutdowns due to COVID-19 have had a devastating effect on commercial real estate.

Over time, the order is fairly random with asset classes moving up and down the ranks. For example, emerging market stocks plummeted to last place amid the global financial crisis in 2008, only to rise to the top the following year. International bonds were near the bottom of the barrel in 2017, but rose to the top during the 2018 market selloff.

There are also large swings in the returns investors can expect in any given year. While the best-performing asset class returned just 1% in 2018, it returned a whopping 71.5% in 2009.

Variation Within Asset Classes

Within individual asset classes, the range in returns can also be quite large. Here’s the minimum, maximum, and average returns for each asset class. We’ve also shown each investment’s standard deviation, which is a measure of volatility or risk.

Return Variation Within Asset Classes Over History

Although emerging market stocks have seen the highest average return, they have also seen the highest standard deviation. On the flip side, T-bills have seen returns lower than inflation since 2009, but have come with the lowest risk.

Investors should factor in risk when they are looking at the return potential of an asset class.

Variety is the Spice of Portfolios

Upon reviewing the historical returns by asset class, there’s no particular investment that has consistently outperformed. Rankings have changed over time depending on a number of economic variables.

However, having a variety of asset classes can ensure you are best positioned to take advantage of tailwinds in any particular year. For instance, bonds have a low correlation with stocks and can cushion against losses during market downturns.

If your mirror could talk, it would tell you there’s no one asset class to rule them all—but a mix of asset classes may be your best chance at success.

The Population Race: A 300-Year Look at China vs. India

When will India’s population overtake China’s? Take a look at the trends behind this impending demographic milestone.

Published

The Population Race: A 300-Year Look at China vs. India

One of the biggest demographic milestones that our world faces is less than a decade away.

Today, China and India boast the largest populations, outpacing all others by a mile. The total populations of these two nations have been climbing for years, but India is moving at a faster clip. The big question is: When will India overtake China in population?

This interactive chart by Our World in Data pulls past and projected population data from the United Nations, comparing the 300-year trajectory of China vs. India to answer this burning question.

China vs. India Population (1800-2100p)

In 1800, India’s population was at a modest 169 million. In contrast, the Chinese population was nearly double that with 322 million at the turn of the 19th century.

It wasn’t until 1950 that the total populations of both countries started shooting up exponentially, and here’s where it starts to get interesting. China reached the 1 billion milestone in 1980, while India took a little longer to get there in 1997.

And now, India is on target to overtake China’s total population in 2026, when both countries are expected to be at the 1.46 billion people mark.

Country18002026p2100pAbsolute change (1800-2100)Relative change
🇨🇳 China321.68M1.46B1.06B+743.3M231%
🇮🇳 India168.57M1.46B1.45B+1.28B758%

*Note: Absolute change numbers may not be exact due to rounding.

Although the populations of both countries will begin contracting in the mid-21st century, India is expected to stay atop the global population leaderboard even by more moderate estimates.

China vs. India Demographics

While it appears that population growth in India is effectively mirroring that of China, there’s more to examine under the surface.

What demographic trends lie behind the eventual contraction later this century? Let’s look at the two population pyramids to find out.

In China, growth has been underscored by a strict “one-child” policy, implemented in 1979. Even with the updated “two-child” policy in 2016, there’s no coming back from this decision—China is now contending with a rapidly aging population. It’s anticipated that over one-third of Chinese citizens will be 65 years old and above by 2050.

Meanwhile in neighboring India, the workforce is just beginning to take off—65% of its population is currently aged 35 years and below. High rates of digital adoption are further compounding economic growth in the country, especially as the world becomes increasingly reliant on telecom and IT services.

China vs. India Economy

Another question this dramatic change begs is: at these rates of population change, can India’s GDP growth also surpass China’s in the next several decades?

The short answer is likely a no, although both countries will still see immense GDP gains during this time. According to PwC, six of the seven largest economies in the world by 2050 will be today’s emerging markets—led by China and India in that order.

CountryGDP (PPP) 2016GDP (PPP) 2050Share of global
GDP (2050)
Change
(2016-2050)
🇨🇳 China$21.3T$58.5T20%+2% (p.p.)
🇮🇳 India$8.7T$44.1T15%+8% (p.p.)
🇺🇸 U.S.$18.6T$34.1T12%-4% (p.p.)

While India isn’t likely to be the “next” China in terms of global GDP, it’s certainly giving it a fair fight as a potential rising superpower—and it all stems from the combined might of its growing population.
