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.

War and Peace: How Violence is Disrupting the Global Economy

This graphic estimates the direct and indirect costs associated with violence, and explores how they are negatively impacting the global economy.

War and Peace: How Violence is Disrupting the Global Economy

Although you may not see it, millions of lives are disrupted by violence everyday.

War, homicide, terrorism, suicide, and sexual assault can be found across the world in various degrees. While certain types of violence can incur costs that result in personal traumas, violence can also create significant economic disruptions.

In today’s Chart of the Week, we visualize data estimates from the Global Peace Index 2019 on the global cost of violence, and its geographical spread.

How is Violence Linked to the Economy?

The Global Peace Index calculates the total cost of violence using purchasing power parity (PPP) by considering three factors:

  • Direct costs: Immediate consequences to the victims, perpetrators and the government
  • Indirect costs: Delayed economic losses following the violent event, including the after-effects of trauma experienced by the victim
  • Multiplier effect: Calculates the additional economic activity that would have accrued if the direct costs of violence had been avoided.

Between 2012-2017, the cost of violence increased by 11% to $14.6 trillion—mainly due to rising violence in Syria, Libya, Yemen, and other parts of the Middle East and North Africa.

In 2018, the total cost of violence decreased for the first time in six years to $14.1 trillion. That’s the equivalent of 11.2% of global GDP (PPP), or $1,853 for every person.

In this one year, the $475 billion saved from decreased violence costs was largely due to lower levels of armed conflict in Syria, Ukraine, and Colombia.

The Top 10 Worst Affected Countries

It comes as no surprise that countries affected by conflict incur the greatest costs due to a higher than average death toll, and sizable military expenditures.

Here are the countries with the highest cost of violence according to the report:

RankCountryCost of violence (% of GDP)    
#1🇸🇾 Syria67%
#2🇦🇫 Afghanistan47%
#3🇨🇫 Central African Republic42%
#4🇰🇵 North Korea34%
#5🇮🇶 Iraq32%
#6🇻🇪 Venezuela30%
#7🇨🇾 Cyprus30%
#8🇸🇴 Somalia26%
#9🇨🇴 Colombia25%
#10🇸🇻 El Salvador22%

Since 2017, Venezuela has climbed the ranking and now sits in the top 10, due to continuing political repression and a spiraling economy as a result of hyperinflation.

The Global Composition of Violence

Government spending on military comprises 40% of the global total, or $5.7 trillion in constant purchasing power parity (PPP).

Type of economic impactShare of total     
Military expenditure
40.2%
Internal security expenditure
31.7%
Homicide
8.6%
Private security expenditure5.8%
Suicide5.2%
Armed conflict4.8%
Violent crime2.6%
Other1%

Naturally, the types of violence costs vary by region, and the most noticeable difference is in military expenditure. It represents 59% of Middle East and North Africa’s violence costs—but only 8% for Central America and the Caribbean.

regional costs violence

Interestingly, the Middle East and North Africa boast the lowest levels of violent crime, homicide, and suicide, representing only 4% of the total, compared to South America’s 45%.

Keeping the Peace

Despite today’s chart painting a picture of the world as a dangerous place, it is worth noting that there are two sides to this story.

Of the 163 countries ranked in the index, 86 countries improved their peace score in the last year, with Iceland retaining its number one position for over a decade. In fact, the country has not had any gun murders since the Global Peace Index began in 2007.

Is the recent drop in costs of violence a sign that we are moving towards a more peaceful planet, or just a blip on the radar?

Ranked: The 20 Easiest Countries for Doing Business

Entrepreneurship is challenging at the best of times. Here are the countries where at least starting a new business is easy to do.

Easiest Countries to do Business

Ranked: The 20 Easiest Countries for Doing Business

Contrary to popular belief, the hardest part about running a business may not be finding customers, it’s getting one started.

Depending on the public policies and application processes of your country, you might struggle or succeed in opening and operating a business.

If you live in New Zealand, for example, you can get a new enterprise up and running in half a day. If you live in Luxembourg or Argentina, however, it’s a different story─with the process sometimes taking over a year.

Today’s chart uses data from the World Bank’s annual Doing Business 2020 report, which delves into the ease of doing business in countries around the world.

Measuring the Ease of Doing Business

Now in its 17th year, the Doing Business (DB) report measures how easy it is for someone to start and run a company in an economy, using 12 key factors throughout a business lifecycle:

  1. Starting a business
  2. Employing workers
  3. Dealing with construction permits
  4. Getting electricity
  5. Registering property
  6. Getting credit
  7. Protecting minority investors
  8. Paying taxes
  9. Trading across borders
  10. Contracting with the government
  11. Enforcing contracts
  12. Resolving insolvency

Of the 190 countries reviewed last year, only 115 made it easier for entrepreneurs to do business.

Note to readers: this year’s DB score did not factor in Employing Workers or Contracting with the Government when ranking economies.

Top 20 Easiest Countries to Run a Business

#2🇸🇬 Singapore86.2
#3🇭🇰 Hong Kong85.3
#4🇩🇰 Denmark85.3
#5🇰🇷 South Korea84
#6🇺🇸 United States84
#7🇬🇪 Georgia83.7
#8🇬🇧 United Kingdom83.5

#16🇦🇪 United Arab Emirates80.9
#17🇲🇰 North Macedonia80.7
#18🇪🇪 Estonia80.6
#19🇱🇻 Latvia80.3
#20🇫🇮 Finland80.2

In the top spot for the fourth year in a row, New Zealand only requires half a day to start a business. Singapore also stands out for having the shortest timeframe when it comes to paying business taxes and enforcing business contracts.

Only two African nations─Rwanda and Mauritius─are listed in the top 50 countries, with Mauritius being the only one to crack the top 20 list.

Latin American economies are noticeably missing from the rankings, as many countries in this region are fraught with bureaucracy and prolonged processes.

Most Improved Scores

Several developed and developing economies made significant strides in 2019 to implement reforms that opened doors for new business owners.

The Doing Business 2020 report shows that the cost of starting a business has fallen over time, particularly in developing economies.

Top 10 Most Improved Economies, 2018-2019

Top 10 most improved economies for doing business

Saudi Arabia made the greatest improvement overall, adding 7.7 points to its score.

Bahrain also made improvements over the most number of factors (9). While Jordan showed improvement in the fewest factors (3), it showed the second highest jump in DB Score.

Gains Among Low-Income Countries

The DB 2020 study also shows that developing economies are making progress: it’s now cheaper than ever before to run a business in developing economies.

However, a significant disparity still remains when we consider the difference in business costs between high-income and low-income economies.

An entrepreneur starting a company in a low-income economy will spend about 50% of per capita income (PCI) to launch a venture, whereas an entrepreneur in a high-income economy spends only 4% PCI to accomplish the same task.

Put another way, entrepreneurs located in the bottom 50 economies spend an average six times more to open a new company as those in a high-income economy.

Entrepreneurship and Economic Growth

Generally, more entrepreneurs will enter a market where they can easily conduct business─adding more value to local economies.

While the rankings clearly illustrate the link between ease of doing business and economic growth, there are still significant barriers in place that not only deter entrepreneurship but also inhibit a relatively simple strategy for growth.
