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.

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: Personal Finance Education Requirements, by State
Only 22.7% of U.S. students are required to take a personal finance course. Which states have the highest levels of personal finance education?
The Percentage of Students Receiving Personal Finance Education
When you graduated from high school, did you know how to create a budget? Did you have an understanding of what stocks and bonds were? Did you know how to do your own taxes?
For many Americans, the answer to these questions is probably a “no”. Only 22.7% of U.S. high school students are guaranteed to receive a personal finance education. While this is up from 16.4% in 2018, this still represents a small fraction of students.
This graphic uses data from Next Gen Personal Finance (NGPF) to show the percentage of high school students required to take a personal finance course by state.
A Closer Look at State-level Personal Finance Education
A standalone personal finance course was defined as a course that was at least one semester, which is equivalent to 60 consecutive instructional hours. Here’s the percentage of students in each state who have a required (not optional) personal finance course.
|State/Territory||% of Students Required to Take Personal Finance Course|
Eight states currently have state-wide requirements for a personal finance course: Alabama, Mississippi, Missouri, Iowa, North Carolina, Tennessee, Utah, and Virginia. Naturally, the level of personal finance education is highest in these states.
Five states have begun the process of implementing a requirement, with Florida being the most populous state yet to guarantee personal finance education for high schoolers. The state previously required schools to offer a personal finance course as an elective, but only 5% of students took the course.
Outside of the guarantee states, only 9.3% of students are required to take a personal finance course. That number drops to 5% for schools that have a high percentage of Black or Brown students, while students eligible for a free or reduced lunch program (i.e. lower income students) also hover at the 5% number.
Why is Personal Financial Education Important?
The majority of Americans believe parents are responsible for teaching their children about personal finance. However, nearly a third of parents say they never talk to their children about finances. Personal finance education at school is one way to help fill that gap.
People who have received a financial education tend to have a higher level of financial literacy. In turn, this can lead to people being less likely to face financial difficulties.
People with low levels of financial literacy were five times more likely to be unable to cover one month of living expenses, when compared to people with high financial literacy. Separate research has found that implementing a state mandate for personal finance education led to improved credit scores and reduced delinquency rates.
Not only that, financial education can play a key role in building wealth. One survey found that only one-third of millionaires averaged a six-figure income over the course of their career. Instead of relying on high salaries, the success of most millionaires came from employing basic personal finance principles: investing early and consistently, avoiding credit card debt, and spending carefully using tools like budgets and coupons.
Expanding Access to Financial Education
Once the in-progress state requirements have been fully implemented, more than a third of U.S. high school students will have guaranteed access to a personal finance course. Momentum is expanding beyond guarantee states, too. There are 48 personal finance bills pending in 18 states according to NGPF’s financial education bill tracker.
Importantly, 88% of surveyed adults support personal finance education mandates—and most wish they had also been required to take a personal finance course themselves.
When we ask the next generation of graduates if they understand how to build a budget, it’s more likely that they will confidently say “yes”.
Charted: U.S. Consumer Debt Approaches $16 Trillion
Robust growth in mortgages has pushed U.S. consumer debt to nearly $16 trillion. Click to gain further insight into the situation.
Charted: U.S. Consumer Debt Approaches $16 Trillion
According to the Federal Reserve (Fed), U.S. consumer debt is approaching a record-breaking $16 trillion. Critically, the rate of increase in consumer debt for the fourth quarter of 2021 was also the highest seen since 2007.
This graphic provides context into the consumer debt situation using data from the end of 2021.
Housing Vs. Non-Housing Debt
The following table includes the data used in the above graphic. Housing debt covers mortgages, while non-housing debt covers auto loans, student loans, and credit card balances.

Trends in Housing Debt
Home prices have experienced upward pressure since the beginning of the COVID-19 pandemic. This is evidenced by the Case-Shiller U.S. National Home Price Index, which has increased by 34% since the start of the pandemic.
Driving this growth are various pandemic-related impacts. For example, the cost of materials such as lumber have seen enormous spikes. We’ve covered this story in a previous graphic, which showed how many homes could be built with $50,000 worth of lumber. In most cases, these higher costs are passed on to the consumer.
Another key factor here is mortgage rates, which fell to all-time lows in 2020. When rates are low, consumers are able to borrow in larger quantities. This increases the demand for homes, which in turn inflates prices.
Ultimately, higher home prices translate to more mortgage debt being incurred by families.
No Need to Worry, Though
Economists believe that today’s housing debt isn’t a cause for concern. This is because the quality of borrowers is much stronger than it was between 2003 and 2007, in the years leading up to the financial crisis and subsequent housing crash.
In the chart below, subprime borrowers (those with a credit score of 620 and below) are represented by the red-shaded bars:
We can see that subprime borrowers represent very little (2%) of today’s total originations compared to the period between 2003 to 2007 (12%). This suggests that American homeowners are, on average, less likely to default on their mortgage.
Economists have also noted a decline in the household debt service ratio, which measures the percentage of disposable income that goes towards a mortgage. This is shown in the table below, along with the average 30-year fixed mortgage rate.
|Year||Mortgage Payments as a % of Disposable Income||Average 30-Year Fixed Mortgage Rate|
Source: Federal Reserve
While it’s true that Americans are less burdened by their mortgages, we must acknowledge the decrease in mortgage rates that took place over the same period.
With the Fed now increasing rates to calm inflation, Americans could see their mortgages begin to eat up a larger chunk of their paycheck. In fact, mortgage rates have already risen for seven consecutive weeks.
Trends in Non-Housing Consumer Debt
The key stories in non-housing consumer debt are student loans and auto loans.
The former category of debt has grown substantially over the past two decades, with growth tapering off during the pandemic. This can be attributed to COVID relief measures which have temporarily lowered the interest rate on direct federal student loans to 0%.
Additionally, these loans were placed into forbearance, meaning 37 million borrowers have not been required to make payments. As of April 2022, the value of these waived payments has reached $195 billion.
Over the course of the pandemic, very few direct federal borrowers have made voluntary payments to reduce their loan principal. When payments eventually resume, and the 0% interest rate is reverted, economists believe that delinquencies could rise significantly.
Auto loans, on the other hand, are following a similar trajectory as mortgages. Both new and used car prices have risen due to the global chip shortage, which is hampering production across the entire industry.
To put this in numbers, the average price of a new car has climbed from $35,600 in 2019, to over $47,000 today. Over a similar timeframe, the average price of a used car has grown from $19,800, to over $28,000.
