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.

News Explainer: The Economic Crisis in Sri Lanka

Sri Lanka is currently in an economic crisis with over $50 billion in debt and consumer inflation at 39%. So how did they get here?

Explained: the Economic Crisis in Sri Lanka

Sri Lanka is currently in an economic and political crisis of mass proportions, recently culminating in a default on its debt payments. The country is also nearly at empty on their foreign currency reserves, decreasing the ability to purchase imports and driving up domestic prices for goods.

There are several reasons for this crisis and the economic turmoil has sparked mass protests and violence across the country. This visual breaks down some of the elements that led to Sri Lanka’s current situation.

A Timeline of Events

The ongoing problems in Sri Lanka have bubbled up after years of economic mismanagement. Here’s a brief timeline looking at just some of the recent factors.

2009

In 2009, a decades-long civil war in the country ended and the government’s focus turned inward towards domestic production. However, a stress on local production and sales, instead of exports, increased the reliance on foreign goods.

2019

Unprompted cuts were introduced on income tax in 2019, leading to significant losses in government revenue, draining an already cash-strapped country.

2020

The COVID-19 pandemic hit the world causing border closures globally and stifling one of Sri Lanka’s most lucrative industries. Prior to the pandemic, in 2018, tourism contributed nearly 5% of the country’s GDP and generated over 388,000 jobs. In 2020, tourism’s share of GDP had dropped to 0.8%, with over 40,000 jobs lost to that point.

2021

Recently, the Sri Lankan government introduced a ban on foreign-made chemical fertilizers. The ban was meant to counter the depletion of the country’s foreign currency reserves.

However, with only local, organic fertilizers available to farmers, a massive crop failure occurred and Sri Lankans were subsequently forced to rely even more heavily on imports, further depleting reserves.

April 2022

In early April this year, massive protests calling for President Gotabaya Rajapaksa’s resignation, sparked in Sri Lanka’s capital city, Colombo.

May 2022

In May, pro-government supporters brutally attacked protesters. Subsequently, Prime Minister Mahinda Rajapaksa, brother of President Rajapaksa, stepped down and was replaced with former PM, Ranil Wickremesinghe.

June 2022

Recently, the government approved a four-day work week to allow citizens an extra day to grow food, as prices continue to shoot up. Food inflation increased over 57% in May.

Additionally, the increasing prices on grain caused by the war in Ukraine and rising fuel prices globally have played into an already dire situation in Sri Lanka.

The Key Information

“Our economy has completely collapsed.”
Prime minister Ranil Wickremesinghe to Parliament last week.

One of the main causes of the economic crisis in Sri Lanka is the reliance on imports and the amount spent on them. Let’s take a look at the numbers:

  • 2021 total imports = $20.6 billion USD
  • 2022 total imports (to March) = $5.7 billion USD

In contrast, the most recent reported foreign currency reserve levels in the country were at an abysmal $50 million, having plummeted an astounding 99%, from $7.6 billion in 2019.

Some of the top imports in 2021, according to the country’s central bank were:

  • Refined petroleum = $2.8 billion
  • Textiles = $3.1 billion
  • Chemical products = $1.1 billion
  • Food & beverage = $1.7 billion

Of course, without the cash to purchase these goods from abroad, Sri Lankans face an increasingly drastic situation.

Additionally, the debt Sri Lanka has incurred is huge, further hampering their ability to boost their reserves. Recently, they defaulted on a $78 million loan from international creditors, and in total, they’ve borrowed $50.7 billion.

The largest source of their debt is by far due to market borrowings, followed closely by loans taken from the Asian Development Bank, China, and Japan, among others.

What it Means

Sri Lanka is home to more than 22 million people who are rapidly losing the ability to purchase everyday goods. Consumer inflation reached 39% at the end of May.

Due to power outages meant to save energy and fuel, schools are currently shuttered and children have nowhere to go during the day. Protesters calling for the president’s resignation have been camped in the capital for months, facing tear gas from police and backlash from president Rajapaksa’s supporters, but many have also responded violently to pushback.

India and China have agreed to send help to the country and the the International Monetary Fund recently arrived in the country to discuss a bailout. Additionally, the government has sent ministers to Russia to discuss a deal for discounted oil imports.

A Foreshadowing for Low Income Countries

Governments need foreign currency in order to purchase goods from abroad. Without the ability to purchase or borrow foreign currency, the Sri Lankan government cannot buy desperately needed imports, including food staples and fuel, causing domestic prices to rise.

Furthermore, defaults on loan payments discourage foreign direct investment and devalue the national currency, making future borrowing more difficult.

What’s happening in Sri Lanka may be an ominous preview of what’s to come in other low and middle-income countries, as the risk of debt distress continues to rise globally.

The Debt Service Suspension Initiative (DSSI) was implemented by G20 countries, suspending nearly $13 billion in debt from the start of the pandemic until late 2021.

ℹ️ This visual reveals the share of DSSI countries that are also low income (LIC) and have had their debt sustainability analyzed, finding that the share close to debt distress is rising over time.

Some DSSI and LIC countries facing a high risk of debt distress include Zambia, Ethiopia, and Tajikistan, to name a few.

Going forward, Sri Lanka’s next steps in managing this situation will either serve as a useful example for other countries at risk or a warning worth heeding.

Interest Rate Hikes vs. Inflation Rate, by Country

Inflation rates are reaching multi-decade highs in some countries. How aggressive have central banks been with interest rate hikes?

Interest Rate Hikes vs. Inflation Rate, by Country

Imagine today’s high inflation like a car speeding down a hill. In order to slow it down, you need to hit the brakes. In this case, the “brakes” are interest rate hikes intended to slow spending. However, some central banks are hitting the brakes faster than others.

This graphic uses data from central banks and government websites to show how policy interest rates and inflation rates have changed since the start of the year. It was inspired by a chart created by Macrobond.

How Do Interest Rate Hikes Combat Inflation?

To understand how interest rates influence inflation, we need to understand how inflation works. Inflation is the result of too much money chasing too few goods. Over the last several months, this has occurred amid a surge in demand and supply chain disruptions worsened by Russia’s invasion of Ukraine.

In an effort to combat inflation, central banks will raise their policy rate. This is the rate they charge commercial banks for loans or pay commercial banks for deposits. Commercial banks pass on a portion of these higher rates to their customers, which reduces the purchasing power of businesses and consumers. For example, it becomes more expensive to borrow money for a house or car.

Ultimately, interest rate hikes act to slow spending and encourage saving. This motivates companies to increase prices at a slower rate, or lower prices, to stimulate demand.

Rising Interest Rates and Inflation

With inflation rates hitting multi-decade highs in some countries, many central banks have announced interest rate hikes. Below, we show how the inflation rate and policy interest rate have changed for select countries and regions since January 2022. The jurisdictions are ordered from highest to lowest current inflation rate.

JurisdictionJan 2022 InflationMay 2022 InflationJan 2022 Policy RateJun 2022 Policy Rate
UK5.50%9.10%0.25%1.25%
U.S.7.50%8.60%0.00%-0.25%1.50%-1.75%
Euro Area5.10%8.10%0.00%0.00%
Canada5.10%7.70%0.25%1.50%
Sweden3.90%7.20%0.00%0.25%
New Zealand5.90%6.90%0.75%2.00%
Norway3.20%5.70%0.50%1.25%
Australia3.50%5.10%0.10%0.85%
Switzerland1.60%2.90%-0.75%-0.25%
Japan0.50%2.50%-0.10%-0.10%

The Euro area has 3 policy rates; the data above represents the main refinancing operations rate. Inflation data is as of May 2022 except for New Zealand and Australia, where the latest quarterly data is as of March 2022.

The U.S. Federal Reserve has been the most aggressive with its interest rate hikes. It has raised its policy rate by 1.5% since January, with half of that increase occurring at the June 2022 meeting. Jerome Powell, the Federal Reserve chair, said the committee would like to “do a little more front-end loading” to bring policy rates to normal levels. The action comes as the U.S. faces its highest inflation rate in 40 years.

On the other hand, the European Union is experiencing inflation of 8.1% but has not yet raised its policy rate. The European Central Bank has, however, provided clear forward guidance. It intends to raise rates by 0.25% in July, by a possibly larger increment in September, and with gradual but sustained increases thereafter. Clear forward guidance is intended to help people make spending and investment decisions, and avoid surprises that could disrupt markets.

Pacing Interest Rate Hikes

Raising interest rates is a fine balancing act. If central banks raise rates too quickly, it’s like slamming the brakes on that car speeding downhill: the economy could come to a standstill. This occurred in the U.S. in the 1980’s when the Federal Reserve, led by Chair Paul Volcker, raised the policy rate to 20%. The economy went into a recession, though the aggressive monetary policy did eventually tame double digit inflation.

However, if rates are raised too slowly, inflation could gather enough momentum that it becomes difficult to stop. The longer high price increases linger, the more future inflation expectations build. This can result in people buying more in anticipation of prices rising further, perpetuating high demand.

“There’s always a risk of going too far or not going far enough, and it’s going to be a very difficult judgment to make.” — Jerome Powell, U.S. Federal Reserve Chair

It’s worth noting that while central banks can influence demand through policy rates, this is only one side of the equation. Inflation is also being caused by supply chain issues, a problem that is more or less outside of the control of central banks.
