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).

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 domain name—equivalent to roughly 7% of the country’s GDP.

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.

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 3 Billion People Who Can’t Afford a Healthy Diet

More than three billion people across the globe are unable to afford a healthy diet. See which countries are most affected.



The 3 Billion People Who Can’t Afford a Healthy Diet

While they aren’t often the focus of news media, hunger and undernourishment are problems plaguing millions of people every day.

According to the UN Food and Agriculture Organization (FAO), more than 3 billion people could not afford a healthy diet in 2020, an additional 112 million more people than in 2019. The increase was partly because of rising food prices, with the average cost of a healthy diet rising by 3.3% from 2019 levels.

As of August 2022, the FAO food price index was up 40.6% from average 2020 levels. Unless income levels increased by a similar magnitude, the healthy diet crisis is likely to have worsened, especially in low-income countries experiencing rampant food inflation.

Using data from the FAO, the above infographic maps the share of people unable to afford a healthy diet in 138 different countries as of 2020 (latest available data).

The Cost and Affordability of a Healthy Diet

According to the FAO, a healthy diet is one that meets daily energy needs as well as requirements within the food and dietary guidelines created by the country.

The (un)affordability is measured by comparing the cost of a healthy diet to income levels in the country. If the cost exceeds 52% of an average household’s income, the diet is deemed unaffordable.

Here’s a look at the share of populations unable to afford a healthy diet, and the cost of such a diet around the world:

In 52 countries, more than half of the population cannot afford a healthy diet. The majority of these are in Africa, with the rest located across Asia, Oceania, and the Americas.

By contrast, in four countries—Azerbaijan, Iceland, Switzerland, and the UAE—everyone is able to afford a healthy diet. The picture is similar for most European and developed high-income countries, where more than 95% of the population can afford a healthy diet.

When the percentages are translated into numbers, Asia contains the most number of people unable to afford a healthy diet at 1.89 billion, of which 973 million people are in India alone. Another 1 billion people are in Africa, with around 151 million people in the Americas and Oceania.

While hunger is a worldwide concern, it is particularly acute in African countries, which cover all of the top 20 spots in the above table.

Africa’s Deepening Food Crisis

In many countries across sub-Saharan Africa, more than 90% of the population cannot afford a healthy diet.

Sub-Saharan Africa is particularly susceptible to extreme climate events and the resulting volatility in food prices. Roughly one-third of the world’s droughts occur in the region, and some sub-Saharan countries are also heavily reliant on imports for food.

Russia’s invasion of Ukraine has deepened the crisis, with many African countries importing over 50% of their wheat from the two countries in conflict. The rising food prices from this supply chain disruption have resulted in double-digit food inflation in many African nations, which means that more people are likely to be unable to afford healthy diets.

The Horn of Africa region at the Eastern tip of Africa is particularly in turmoil. All the countries in the region are reliant on wheat from Russia and Ukraine, with Eritrea (100%) and Somalia (>90%) high up in the import dependency chart. Additionally, the region is facing its worst drought in 40 years alongside ongoing political conflicts. As a result, 22 million people are at risk of starvation.

Population Growth and Food Insecurity

In November of 2022, the global population is projected to surpass 8 billion people, and many of the fastest growing countries are also food-insecure.

By 2050, the global population is likely to increase by 35%, and to meet the growing demand for food, crop production will need to double. Given that agriculture is one of the biggest contributors to greenhouse gas emissions, this increase in crop production will also need to be environmentally sustainable.

As the impacts of climate change intensify and food demand increases, reducing food waste, building climate-resilient agricultural infrastructure, and improving agricultural productivity will all play a key role in reducing the levels of food insecurity sustainably.

How Do Americans Spend Their Money, By Generation?

This interactive graphic shows a breakdown of how average Americans spend their money, and how expenses vary across generations.



Annual Expenditure in the U.S. by Generation

How Americans Spend Their Money, By Generation

In 2021, the average American spent just over $60,000 a year. But where does all their money go? Unsurprisingly, spending habits vary wildly depending on age.

This graphic by Preethi Lodha uses data from the U.S. Bureau of Labor Statistics to show how average Americans spend their money, and how annual expenses vary across generations.

A Generational Breakdown of Overall Spending

Overall in 2021, Gen X (anyone born from 1965 to 1980) spent the most money of any U.S. generation, with an average annual expenditure of $83,357.

GenerationBirth Year RangeAverage Annual Expenditure (2021)
Silent1945 or earlier$44,683
Boomers1946 to 1964$62,203
Generation X1965 to 1980$83,357
Millennials1981 to 1996$69,061
Generation Z1997 or later$41,636

Gen X has been nicknamed the “sandwich generation” because many members of this age group are financially supporting both their aging parents as well as children of their own.

The second biggest spenders are Millennials with an average annual expenditure of $69,061. Just like Gen X, this generation’s top three spending categories are housing, healthcare, and personal insurance.

On the opposite end of the spectrum, members of Generation Z are the lowest spenders with an average of $41,636. per year. Their spending habits are expected to ramp up, especially considering that in 2022 the oldest Gen Zers are just 25 and still early in their careers.

Similarities Across Generations

While spending habits vary depending on the age group, there are some categories that remain fairly consistent across the board.

One of the most consistent spending categories is housing—it’s by the far the biggest expense for all age groups, accounting for more than 30% of total annual spending for every generation.

GenerationAverage Spend on Housing (2021)% of Total Spend
Silent (1945 or earlier)$16,65637.3%
Boomers (1946 to 1964)$21,27334.2%
Generation X (1965 to 1980)$26,38531.7%
Millennials (1981 to 1996)$24,05234.8%
Generation Z (1997 or later)$15,44937.1%

Another spending category that’s surprisingly consistent across every generation is entertainment. All generations spent more than 4% of their total expenditures on entertainment, but none dedicated more than 5.6%.

GenerationAverage Spend on Entertainment (2021)% of Total Spend
Silent (1945 or earlier)$2,0274.5%
Boomers (1946 to 1964)$3,4765.6%
Generation X (1965 to 1980)$4,6945.6%
Millennials (1981 to 1996)$3,4575.0%
Generation Z (1997 or later)$1,6934.1%

Gen Zers spent the least on entertainment, which could boil down to the types of entertainment this generation typically enjoys. For instance, a study found that 51% of respondents aged 13-19 watch videos on Instagram on a weekly basis, while only 15% watch cable TV.

Differences Across Generations

One category that varies the most between generations and relative needs is spending on healthcare.

As the table below shows, the Silent Generation spent an average of $7,053 on healthcare, or 15.8% of their total average spend. Comparatively, Gen Z only spent $1,354 on average, or 3.3% of their total average spend.

GenerationAverage Spend on Healthcare (2021)% of Total Spend
Silent (1945 or earlier)$7,05315.8%
Boomers (1946 to 1964)$6,59410.6%
Generation X (1965 to 1980)$5,5506.7%
Millennials (1981 to 1996)$4,0265.8%
Generation Z (1997 or later)$1,3543.3%

However, while the younger generations typically spend less on healthcare, they’re also less likely to be insured—so those who do get sick could be left with a hefty bill.
