The $94 Trillion World Economy in One Chart
View the expanded version of this infographic.
Just four countries—the U.S., China, Japan, and Germany—make up over half of the world’s economic output by gross domestic product (GDP) in nominal terms. In fact, the GDP of the U.S. alone is greater than the combined GDP of 170 countries.
How do the different economies of the world compare? In this visualization we look at GDP by country in 2021, using data and estimates from the International Monetary Fund (IMF).
An Overview of GDP
GDP serves as a broad indicator for a country’s economic output. It measures the total market value of final goods and services produced in a country in a specific timeframe, such as a quarter or year. In addition, GDP also takes into consideration the output of services provided by the government, such as money spent on defense, healthcare, or education.
Generally speaking, when GDP is increasing in a country, it is a sign of greater economic activity that benefits workers and businesses (while the reverse is true for a decline).
The World Economy: Top 50 Countries
Who are the biggest contributors to the global economy? Here is the ranking of the 50 largest countries by GDP in 2021:
|Rank||Country||GDP ($T)||% of Global GDP|
|19||🇸🇦 Saudi Arabia||$0.8||0.9%|
|33||🇿🇦 South Africa||$0.4||0.4%|
|40||🇭🇰 Hong Kong SAR||$0.4||0.4%|
|47||🇨🇿 Czech Republic||$0.3||0.3%|
|50||🇳🇿 New Zealand||$0.2||0.3%|

At $22.9 trillion, the U.S. GDP accounts for roughly 25% of the global economy, a share that has actually changed significantly over the last 60 years. The finance, insurance, and real estate ($4.7 trillion) industries add the most to the country’s economy, followed by professional and business services ($2.7 trillion) and government ($2.6 trillion).
China’s economy is second in nominal terms, hovering at near $17 trillion in GDP. It remains the largest manufacturer worldwide based on output with extensive production of steel, electronics, and robotics, among others.
The largest economy in Europe is Germany, which exports roughly 20% of the world’s motor vehicles. In 2019, overall trade equaled nearly 90% of the country’s GDP.
The World Economy: 50 Smallest Countries
On the other end of the spectrum are the world’s smallest economies by GDP, primarily developing and island nations.
With a GDP of $70 million, Tuvalu is the smallest economy in the world. Situated between Hawaii and Australia, the largest industry of this volcanic archipelago relies on territorial fishing rights.
In addition, the country earns significant revenue from its “.tv” web domain. Between 2011 and 2019, it earned $5 million annually from companies—including Amazon-owned Twitch to license the Twitch.tv domain name—equivalent to roughly 7% of the country’s GDP.
|🇲🇭 Marshall Islands||Oceania||$0.2|

|🇸🇹 São Tomé and Príncipe||Africa||$0.5|
|🇻🇨 St. Vincent and the Grenadines||Caribbean||$0.8|

Like Tuvalu, many of the world’s smallest economies are in Oceania, including Nauru, Palau, and Kiribati. Additionally, several countries above rely on the tourism industry for over one-third of their employment.
The Fastest Growing Economies in the World in 2021
With 123% projected GDP growth, Libya’s economy is estimated to have the sharpest rise.
Oil is propelling its growth, with 1.2 million barrels being pumped in the country daily. Along with this, exports and a depressed currency are among the primary factors behind its recovery.
2021 Real GDP Growth (Annual % Change)
|2||🇬🇾 Guyana||South America||20.4%|
|7||🇵🇦 Panama||Central America||12.0%|
|8||🇨🇱 Chile||South America||11.0%|
|9||🇵🇪 Peru||South America||10.0%|
|10||🇩🇴 Dominican Republic||Caribbean||9.5%|
Ireland’s economy, with a projected 13% real GDP growth, is being supported by the largest multinational corporations in the world. Facebook, TikTok, Google, Apple, and Pfizer all have their European headquarters in the country, which has a 12.5% corporate tax rate—or about half the global average. But these rates are set to change soon, as Ireland joined the OECD 15% minimum corporate tax rate agreement which was finalized in October 2021.
Macao’s economy bounced back after COVID-19 restrictions began to lift, but more storm clouds are on the horizon for the Chinese district. The CCP’s anti-corruption campaign and recent arrests could signal a more strained relationship between Mainland China and the world’s largest gambling hub.
Looking Ahead at the World’s GDP
The global GDP figure of $94 trillion may seem massive to us today, but such a total might seem much more modest in the future.
In 1970, the world economy was only about $3 trillion in GDP—or 30 times smaller than it is today. Over the next thirty years, the global economy is expected to more or less double again. By 2050, global GDP could total close to $180 trillion.
Correction: In earlier versions of this graphic, countries such as Vietnam and Pakistan were inadvertently not included in the visualization. They have now been added. In cases where the IMF has no data for 2021 (specifically Pakistan, Syria, Afghanistan, and Lebanon), the latest available data is used.
Mapped: The Migration of the World’s Millionaires in 2023
Where do the world’s wealthiest people want to live? This map tracks the migration of the world’s High Net Worth Individuals (HNWIs).
Mapping the Migration of the World’s Millionaires 2023
Just like everyone else, High Net Worth Individuals (HNWIs) traveled less than usual during the pandemic, and as a result their migration numbers trended downwards. But millionaires and billionaires are on the move again and it is anticipated that 122,000 HNWIs will move to a new country by the end of the year.
Henley & Partners’ Private Wealth Migration Report has tracked the countries HNWIs have moved from and to over the last 10 years; this map showcases the 2023 forecasts.
In this context, HNWIs are defined as individuals with a net worth of at least $1 million USD.
The Countries Welcoming New Millionaires
The top 10 countries which are likely to become home to the highest number of millionaires and billionaires in 2023 are scattered across the globe, with Australia reclaiming its top spot this year from the UAE.
Here’s a closer look at the data:
|Rank||Country||Projected HNWI Inflow 2023|
|10||🇳🇿 New Zealand||700|
Only two Asian countries make the top 10, with the rest spread across Europe, North America, and Oceania.
Despite historic economic challenges, Greece is projected to gain 1,200 High Net Worth Individuals this year. One reason could be the country’s golden visa program, wherein wealthy individuals can easily obtain residence and eventually EU passports for the right price—currently a minimum real estate investment cost of 250,000 euros is all that’s required.
Many of the leading millionaire destinations are attractive for wealthy individuals because of higher levels of economic freedom, allowing for laxer tax burdens or ease of investment. Singapore, which expects to gain 3,200 millionaires, is the most economically free market in the world.
The Countries Losing the Most Millionaires
China is anticipated to lose 13,500 High Net Worth Individuals this year, more than double as many as the second place country, India (6,500).
Here’s a closer look at the bottom 10:
|Rank||Country||Projected HNWI Outflow 2023|
|6||🇭🇰 Hong Kong SAR||-1,000|
|7||🇰🇷 South Korea||-800|
|9||🇿🇦 South Africa||-500|
In a number of these countries, strict regulatory bodies and corrupt governments can hinder the ease with which HNWIs can manage their own money.
In Russia, many wealthy individuals are facing personal tariffs and trade restrictions from Western countries due to the war in Ukraine. China’s crackdowns on Hong Kong have made it a less attractive place for business. And finally, the UK’s exit from the EU has caused many businesses and individuals to lose the easy movement of labor, finances, and investment that made operations across European borders seamless.
Some of these countries may still be adding homegrown millionaires and billionaires, but losing thousands of HNWIs to net migration does have a considerable economic impact.
Overall, millionaires are increasingly on the move. In the 10 years of reporting—despite a dip during the pandemic—the number of HNWIs moving away from their countries of origin has been growing every year.
Here’s a look at the numbers:
|Year||Projected HNWI Migration|
In a geopolitically fragile but more connected world, it’s no surprise to see millionaires voting with their feet. As a result, governments are increasingly in competition to win the hearts and minds of the world’s economic elite to their side.
