The Economic Impact of America’s International Students
For decades, the U.S. has been the top destination for students looking to study abroad.
It’s easy to see why. Not only does the country provide access to world-class economic hubs like Silicon Valley, but the U.S. is also home to 14 of the top 20 universities in the world, many of which are famed for their research and alumni networks.
Yet, there is cause for concern.
International enrollments in the U.S. have slowed, while other countries are attracting a larger share of the global talent pool. To help us understand what’s at stake if enrollments continue to decline, today’s infographic shows the impact of international students on the U.S. economy.
Driving American Innovation and Growth
International students and scholars are a vital economic asset, and America’s ability to attract them puts the country in an enviable position.
First, there are the direct economic benefits which result from tuition fees and living expenses. Throughout the 2018/2019 school year, these benefits totaled $41 billion, a comparable value to many other American exports:
Even after graduation, however, international students and scholars continue to make significant contributions to the U.S. economy.
For example, attracting the world’s brightest minds helps to grow the knowledge economy in the United States, and 40% of American Nobel Prizes won in chemistry, medicine, and physics since 2000 have been awarded to immigrants. Furthermore, students who return home often do so with a network of connections and an appreciation for American culture, thus promoting U.S. international leadership.
Finally, these individuals can also go on to become successful entrepreneurs and business leaders in the U.S. economy. The list is long, but here are two noteworthy examples:
- Elon Musk, known for founding Paypal, Tesla, and SpaceX, was born in South Africa. He received two Bachelor’s degrees from the University of Pennsylvania before founding his first business.
- Satya Nadella, CEO of Microsoft, was an international student from India. He received an M.S. from the University of Wisconsin and an MBA from the University of Chicago before helping Microsoft develop its cloud computing capabilities.
Cause for Concern
In recent years, however, the number of new international students enrolling at U.S. institutions has been on the decline:
|School Year||New International Student Enrollments in the U.S.||Percent Change|
With so many opportunities and success stories, why have international enrollments slowed? A survey of 509 higher education institutions in the U.S. revealed the top reasons for declining international enrollments:
|Cited Reason for Decline in Enrollment||% of Institutions|
|% of Institutions|
|% of Institutions
|Visa Application Process (delays/denials)||34%||68%||83%|
|Social and Political Environment||15%||57%||60%|
|Enroll in Another Country’s Institutions||19%||54%||59%|
|Cost of Tuition||51%||55%||57%|
|Securing a Job||-||41%||44%|
Critically, the two most common reasons for declining enrollment—visa applications and the social and political environment—suggest that the quality of an American education is not the issue. Rather, it would appear that students are being discouraged from coming to the United States.
When we discourage or turn away international students, we lose much more than the students themselves… We lose their inventions and innovation, their collaborative input and their contributions to our communities.
– Dr. Martha E. Pollack, President, Cornell University
At the same time, other countries are taking proactive measures to attract global talent.
Australia allows its international students to work for up to 18 months after graduation. This limit can increase to 4 years for graduates of high-demand occupations. In 2018, the country saw a 15% increase in international enrollments.
Canada, a country distinguished for its multiculturalism, is quickly becoming an attractive destination for international students. The country offers expedited visa processing for qualified individuals, as well as a 3-year work visa for graduates. In 2017, international enrollments in Canada grew by an impressive 20%.
The world’s brightest minds are an important asset for continued innovation and growth, and today, there is a mass of countries welcoming them with open arms.
While the U.S. is still the preferred destination for international students and scholars, the country’s leadership in this space is at risk. In fact, since 2001, the share of international students in America has fallen from 28% to 21%.
Will the U.S be able to maintain global competitiveness if the number of new international students enrolling continues to fall? Can the country work to cultivate a more welcoming and barrier-free route to higher education?
These are potent questions that will need to be answered, especially with a sizable economic impact on the line.

What is monkeypox, and what risk does it pose to the public? This infographic breaks down the symptoms, transmission, and more.
Explainer: What to Know About Monkeypox
The COVID-19 pandemic is still fresh in the minds of the people around the world, so it comes as no surprise that recent outbreaks of another virus are grabbing headlines.
Monkeypox outbreaks have now been reported in multiple countries, and it has scientists paying close attention. For everyone else, numerous questions come to the surface:
- How serious is this virus?
- How contagious is it?
- Could monkeypox develop into a new pandemic?
Below, we answer these questions and more.
What is Monkeypox?
Monkeypox is a virus in the Orthopoxvirus genus which also includes the variola virus (which causes smallpox) and the cowpox virus. The primary symptoms include fever, swollen lymph nodes, and a distinctive bumpy rash.
There are two major strains of the virus that pose very different risks:
- Congo Basin strain: 1 in 10 people infected with this strain have died
- West African strain: Approximately 1 in 100 people infected with this strain died
At the moment, health authorities in the UK have indicated they’re seeing the milder strain in patients there.
Where did Monkeypox Originate From?
The virus was originally discovered in the Democratic Republic of Congo in monkeys kept for research purposes (hence the name). Eventually, the virus made the jump to humans more than a decade after its discovery in 1958.
It is widely assumed that vaccination against another similar virus, smallpox, helped keep monkeypox outbreaks from occurring in human populations. Ironically, the successful eradication of smallpox, and eventual winding down of that vaccine program, has opened the door to a new viral threat. There is now a growing population of people who no longer have immunity against the virus.
Now that travel restrictions are lifting in many parts of the world, viruses are now able to hop between nations again. As of the publishing of this article, a handful of cases have now been reported in the U.S., Canada, the UK, and a number of European countries.
On the upside, contact tracing has helped authorities piece together the transmission of the virus. While cases are rare in Europe and North America, it is considered endemic in parts of West Africa. For example, the World Health Organization reports that Nigeria has experienced over 550 reported monkeypox cases from 2017 to today. The current UK outbreak originated from an individual who returned from a trip to Nigeria.
Could Monkeypox become a new pandemic?
Monkeypox, which primarily spreads through animal-to-human interaction, is not known to spread easily between humans. Most individuals infected with monkeypox pass the virus to between zero and one person, so outbreaks typically fizzle out. For this reason, the fact that outbreaks are occurring in several countries simultaneously is concerning for health authorities and organizations that monitor viral transmission. Experts are entertaining the possibility that the virus’ rate of transmission has increased.
Images of people covered in monkeypox lesions are shocking, and people are understandably concerned by this virus, but the good news is that members of the general public have little to fear at this stage.
I think the risk to the general public at this point, from the information we have, is very, very low.

The Top 10 Largest Nuclear Explosions, Visualized
Just how powerful are nuclear bombs? Here’s a look at the top 10 largest nuclear explosions.
The Top 10 Largest Nuclear Explosions, Visualized
Just how powerful are nuclear explosions?
The U.S.’ Trinity test in 1945, the first-ever nuclear detonation, released around 19 kilotons of explosive energy. The explosion instantly vaporized the tower it stood on and turned the surrounding sand into green glass, before sending a powerful heatwave across the desert.
As the Cold War escalated in the years after WWII, the U.S. and the Soviet Union tested bombs that were at least 500 times greater in explosive power. This infographic visually compares the 10 largest nuclear explosions in history.
The Anatomy of a Nuclear Explosion
After exploding, nuclear bombs create giant fireballs that generate a blinding flash and a searing heatwave. The fireball engulfs the surrounding air, getting larger as it rises like a hot air balloon.
As the fireball and heated air rise, they are flattened by cooler, denser air high up in the atmosphere, creating the mushroom “cap” structure. At the base of the cloud, the fireball causes physical destruction by sending a shockwave moving outwards at thousands of miles an hour.
A strong updraft of air and dirt particles through the center of the cloud forms the “stem” of the mushroom cloud. In most atomic explosions, changing atmospheric pressure and water condensation create rings that surround the cloud, also known as Wilson clouds.
Over time, the mushroom cloud dissipates. However, it leaves behind radioactive fallout in the form of nuclear particles, debris, dust, and ash, causing lasting damage to the local environment. Because the particles are lightweight, global wind patterns often distribute them far beyond the place of detonation.
With this context in mind, here’s a look at the 10 largest nuclear explosions.
#10: Ivy Mike (1952)
In 1952, the U.S. detonated the Mike device—the first-ever hydrogen bomb—as part of Operation Ivy. Hydrogen bombs rely on nuclear fusion to amplify their explosions, producing much more explosive energy than atomic bombs that use nuclear fission.
Weighing 140,000 pounds (63,500kg), the Ivy Mike test generated a yield of 10,400 kilotons, equivalent to the explosive power of 10.4 million tons of TNT. The explosion was 700 times more powerful than Little Boy, the bomb dropped on Hiroshima in 1945.
#9: Castle Romeo (1954)
Castle Romeo was part of the Operation Castle series of U.S. nuclear tests taking place on the Marshall Islands. Shockingly, the U.S. was running out of islands to conduct tests, making Romeo the first-ever test conducted on a barge in the ocean.
At 11,000 kilotons, the test produced more than double its predicted explosive energy of 4,000 kilotons. Its fireball, as seen below, is one of the most iconic images ever captured of a nuclear explosion.
#8: Soviet Test #123 (1961)
Test #123 was one of the 57 tests conducted by the Soviet Union in 1961. Most of these tests were conducted on the Novaya Zemlya archipelago in Northwestern Russia. The bomb yielded 12,500 kilotons of explosive energy, enough to vaporize everything within a 2.1 mile (3.5km) radius.
#7: Castle Yankee (1954)
Castle Yankee was the fifth test in Operation Castle. The explosion marked the second-most powerful nuclear test by the U.S.
It yielded 13,500 kilotons, much higher than the predicted yield of up to 10,000 kilotons. Within four days of the blast, its fallout reached Mexico City, roughly 7,100 miles (11,400km) away.
#6: Castle Bravo (1954)
Castle Bravo, the first of the Castle Operation series, accidentally became the most powerful nuclear bomb tested by the U.S.
Due to a design error, the explosive energy from the bomb reached 15,000 kilotons, two and a half times what was expected. The mushroom cloud climbed up to roughly 25 miles (40km).
As a result of the test, an area of 7,000 square miles was contaminated, and inhabitants of nearby atolls were exposed to high levels of radioactive fallout. Traces of the blast were found in Australia, India, Japan, and Europe.
#5, #4, #3: Soviet Tests #173, #174, #147 (1962)
In 1962, the Soviet Union conducted 78 nuclear tests, three of which produced the fifth, fourth, and third-most powerful explosions in history. Tests #173, #174, and #147 each yielded around 20,000 kilotons. Due to the absolute secrecy of these tests, no photos or videos have been released.
#2: Soviet Test #219 (1962)
Test #219 was an atmospheric nuclear test carried out using an intercontinental ballistic missile (ICBM), with the bomb exploding at a height of 2.3 miles (3.8km) above sea level. It was the second-most powerful nuclear explosion, with a yield of 24,200 kilotons and a destructive radius of ~25 miles (41km).
#1: Tsar Bomba (1961)
Tsar Bomba, also called Big Ivan, needed a specially designed plane because it was too heavy to carry on conventional aircraft. The bomb was attached to a giant parachute to give the plane time to fly away.
The explosion, yielding 50,000 kilotons, obliterated an abandoned village 34 miles (55km) away and generated a 5.0-5.25 magnitude earthquake in the surrounding region. Initially, it was designed as a 100,000 kiloton bomb, but its yield was cut to half its potential by the Soviet Union. Tsar Bomba’s mushroom cloud breached through the stratosphere to reach a height of over 37 miles (60km), roughly six times the flying height of commercial aircraft.
The two bombs dropped on Hiroshima and Nagasaki had devastating consequences, and their explosive yields were only a fraction of the 10 largest explosions. The power of modern nuclear weapons makes their scale of destruction truly unfathomable, and as history suggests, the outcomes can be unpredictable.
