Now you can see the $94 Trillion World Economy in One Chart [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?

An Overview of GDP

GDP serves as a broad indicator of 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 20 largest countries by GDP in 2021:

Rank	Country	GDP ($T)	% of Global GDP
1	U.S.	$22.9	24.4%
2	China	$16.9	17.9%
3	Japan	$5.1	5.4%
4	Germany	$4.2	4.5%
5	UK	$3.1	3.3%
6	India	$2.9	3.1%
7	France	$2.9	3.1%
8	Italy	$2.1	2.3%
9	Canada	$2.0	2.1%
10	Korea	$1.8	1.9%

Rank	Country	GDP ($T)	% of Global GDP
11	Russia	$1.6	1.7%
12	Brazil	$1.6	1.7%
13	Australia	$1.6	1.7%
14	Spain	$1.4	1.5%
15	Mexico	$1.3	1.4%
16	Indonesia	$1.2	1.2%
17	Iran	$1.1	1.1%
18	Netherlands	$1.0	1.1%
19	Saudi Arabia	$0.8	0.9%
20	Switzerland	$0.8	0.9%

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 an 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: 10 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.

Countries	Region	GDP (B)
Tuvalu	Oceania	$0.07
Nauru	Oceania	$0.1
Palau	Oceania	$0.2
Kiribati	Oceania	$0.2
Marshall Islands	Oceania	$0.2
Micronesia	Oceania	$0.4
Tonga	Oceania	$0.5
São Tomé and Príncipe	Central America	$0.5
Dominica	Caribbean	$0.6
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.

Rank	Country	Region	2021 Real GDP Growth (Annual % Change)
1	Libya	Africa	123.2%
2	Guyana	South America	20.4%
3	Macao	Asia	20.4%
4	Maldives	Asia	18.9%
5	Ireland	Europe	13.0%
6	Aruba	Caribbean	12.8%
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.
