There are up to 8,755 commercial flights in the air at any given time of day. These flights transport thousands of people (and millions of dollars worth of goods) around the world.
But where are these people and goods headed? This map from Adam Symington uses historical data from OpenFlights to visualize the world’s flight paths.
The graphic shows a comprehensive data set encompassing 67,663 different routes that connect 10,000 different airports across the globe.
The map uses an OpenFlights database provided by the third-party source that hasn’t been updated since June 2014.
Because of this, the data used for the graphic is of historical value only. However, this detailed map sparked our curiosity and got us wondering—what are some of the busiest aviation hubs around the world right now?
We did some digging, and here’s what we found.
There are several ways to gauge an airport’s popularity. One way is to measure total passenger traffic throughout the year.
According to Airports Council International (ACI), eight of the top 10 busiest airports for passenger traffic in 2021 were in America. Here’s a look at the top 10 list, as of April 11, 2022:
In 2021, the airport with the most passenger traffic was Hartsfield-Jackson Atlanta International Airport. It accommodated more than 75 million passengers last year—a 76.4% increase compared to 2020 figures.
Hartsfield-Jackson is well-known for being one of the busiest airports in the world. One reason for this is its convenient location—according to the airport’s official website, Atlanta is within a two-hour flight from 80% of the U.S. population.
Dallas/Forth Worth (DFW) came in second place, seeing 62.5 million passengers throughout 2021. DFW was one of the only airports to boost its service offerings throughout the pandemic, and is also the main hub for American Airlines, the world’s largest airline by fleet size.
While the U.S. dominates the ranking when it comes to passenger traffic, the list is much more diverse when looking at air cargo volumes. Here’s a look at the ranking, based on loaded and unloaded freight and mail (including transit freight):
Hong Kong (HKG) takes the top spot since the airport processed more than 5.0 million metric tonnes of freight and mail throughout 2021.
Hong Kong has been known as one of the busiest air cargo hubs for over a decade and is able to maintain this reputation because of its strategic location, impressive infrastructure, efficient customs, and business-friendly trade regulations.
The global pandemic hit the aviation industry hard. At its lowest point, international travel was down 98% from normal levels.
While the aviation industry is starting to recover from its COVID-induced slump, things still haven’t fully bounced back yet, especially in places like Shanghai, where lockdowns are still being mandated.
But experts remain hopeful for the future. According to ACI World’s General Director Luis Felipe de Oliveira, last year’s recovery was just the beginning.
“With many countries taking steps towards the return of a certain normality, lifting almost all the health measures and travel restrictions as supported by science, we welcome the continuation of air travel demand’s recovery in 2022.”

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

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).
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.
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.
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.

EV adoption has grown rapidly in recent years, but many prospective buyers still have doubts about electric car ranges.
In fact, 33% of new car buyers chose range anxiety—the concern about how far an EV can drive on a full charge—as their top inhibitor to purchasing electric cars in a survey conducted by EY.
So, how far can the average electric car go on one charge, and how does that compare with the typical range of gas-powered cars?
Thanks to improvements in battery technology, the average range of electric cars has more than doubled over the last decade, according to data from the International Energy Agency (IEA).

As of 2021, the average battery-powered EV could travel 217 miles (349 km) on a single charge. It represents a 44% increase from 151 miles (243 km) in 2017 and a 152% increase relative to a decade ago.
Despite the steady growth, EVs still fall short when compared to gas-powered cars. For example, in 2021, the median gas car range (on one full tank) in the U.S. was around 413 miles (664 km)—nearly double what the average EV would cover.
As automakers roll out new models, electric car ranges are likely to continue increasing and could soon match those of their gas-powered counterparts. It’s important to note that EV ranges can change depending on external conditions.
In theory, EV ranges depend on battery capacity and motor efficiency, but real-world results can vary based on several factors:
On the contrary, when driven at optimal temperatures of about 70℉ (21.5℃), EVs can exceed their rated range, according to an analysis by Geotab.
Here are the 10 longest-range electric cars available in the U.S. as of 2022, based on Environmental Protection Agency (EPA) range estimates:

The top-spec Lucid Air offers the highest range of any EV with a price tag of $170,500, followed by the Tesla Model S. But the Tesla Model 3 offers the most bang for your buck if range and price are the only two factors in consideration.
