The Yuxi Circle: The World’s Most Densely Populated Area

If you wanted to capture over 55% of the global population inside a circle with a 4,000km radius, which city would you place at its epicenter?

In 2013, a post appeared on Reddit marking a circular area of the globe with “more people living inside this circle than outside of it.” The circle had a radius of 4,000 km (just under 2,500 miles) and was named the Valeriepieris circle after author Ken Myers’ username.

Acknowledging that the Valeriepieris circle is not actually a circle (it was drawn on a two-dimensional map rather than a globe) and is based on data that has become outdated, mapmaker Alasdair Rae went digging and discovered what he calls The Yuxi Circle, the world’s most densely populated area.

Introducing the Yuxi Circle

Rae traced circles around 1,500 cities worldwide to find out how many people lived within a 4,000 km radius, just like the original Valeriepieris circle. He based his calculations on WorldPop data from 2020, based on a global population of 7.8 billion people.

Of the 1,500 circles that Rae made calculations for, 148 contained populations of 4 billion or more. He found many examples in Asia including in China, Myanmar (Mandalay), Laos (Vientiane), Bangladesh (Chattogram), India (Agartala), Bhutan (Thimpu), and Vietnam (Hanoi) to name a few.

But of them all, Yuxi, a city in the Yunnan province of China, has the largest population living within a 4,000 km radius: 4.32 billion.

Put another way? The circle encompasses over 55% of the world’s population, despite including desolate areas like the Taklamakan Desert, the Tibetan Plateau, Mongolia, and Southern Siberia.

Densely Populated Areas Around the Globe

Rae’s search for densely populated clusters also turned up notable circles beyond Asia. They surrounded cities like Cairo, Paris, and Mexico City.

Note: Keep in mind that the white lines on the flat maps are equidistant circles but will only look like circles when plotted on a globe.

The World’s Most Densely Populated Areas - Hanoi

Circling Hanoi yields a population of 4.27 billion (54% of the global population). It was the runner up city circle in Rae’s original search.

Populated Area Circles - Cairo

Circling Cairo yields a population of 2.29 billion. This circle reaches most of Europe while still containing populated areas of India, Pakistan, and Africa.

Populated Area Circles - Paris

Comparatively, circling Paris yields a population of 1.19 billion. This Euro-centric circle contains large tracts of water and scarcely populated islands such as Iceland and Greenland.

Populated Area Circles - Mexico City

Across the Atlantic, circling Mexico City yields a population of 0.73 billion. It’s significantly smaller than the other circles, as the total population in the Americas is concentrated in just three countries, the U.S., Mexico, and Brazil (not included in this circle).

It’s worth noting that the Valeriepieris circle also inspired other people to look at population density in different ways. In 2015, Danny Quah of the London School of Economics looked more closely at the Valeriepieris circle and was inspired to find the smallest circle with more people living inside of it than outside. He determined that a circle with a radius of 3,300 km centered near Mong Khet, Myanmar was “the world’s tightest cluster of people.”

While the Yuxi Circle contains the largest population using Rae’s approach as of early 2022, global populations are constantly changing. Who knows where the next Yuxi Circle will be?

Ranked: The Cities with the Most Skyscrapers in 2023

We rank the world’s leading cities with the most skyscrapers, highlighting China’s remarkable dominance in building vertically.

Ranked: The Cities with the Most Skyscrapers in 2023

When it comes to soaring skylines and architectural marvels, no country has embraced the vertical revolution quite like China.

In this graphic, which uses data from the Council on Tall Buildings and Urban Habitat (CTBUH), we reveal the 25 cities with the most skyscrapers and supertall buildings globally.

Unsurprisingly, China’s cities dominate the list, solidifying the country’s reputation as a global powerhouse of tall buildings.

The 25 Top Cities by Skyscraper Count

Topping the charts is Hong Kong, with an impressive 657 skyscrapers, including six supertalls (buildings over 300 meters tall).

Hong Kong, along with Shenzhen (#2), and Guangzhou (#5) are part of the burgeoning megacity known as the Pearl River Delta, which is home to over 1,500 skyscrapers. This is even more impressive when considering that Shenzhen was a small fishing village until the 1970s.

New York City secures the third position on the list, boasting an impressive tally of 421 skyscrapers. Although it may have relinquished its title to Chinese cities, the city’s skyline endures as a globally renowned symbol, prominently featuring the iconic Empire State Building. Notably, while the Empire State Building enjoys widespread familiarity, it no longer ranks among the world’s 50 tallest structures.

Rounding out the top five is Dubai in the United Arab Emirates, which grabs the fourth position with 395 skyscrapers, a staggering 28 of which are supertalls. This desert oasis has become synonymous with grandiose architecture and record-breaking structures, exemplified by the Burj Khalifa, which is the world’s current tallest building at 828 meters (2,715 ft).

China’s Numbers in Context

Looking at this data from another perspective, China actually has more skyscrapers on this list than the rest of the world combined.

China’s rapid urbanization, economic growth, and ambitious construction projects have fueled this impressive feat. There’s no doubt that the country’s relentless pursuit of vertical development, coupled with its booming population and thriving cities, has positioned China as the unrivaled leader in the global skyscraper race.

The Future of the Global Skyline

As the world continues to reach new heights in architectural marvels, there are even more supertall skyscrapers in the pipeline that will reshape skylines across the globe.

From the soaring Jeddah Tower in Saudi Arabia, poised to surpass the Burj Khalifa as the world’s tallest building, to the remarkable Merdeka 118 in Kuala Lumpur, which is set to claim the title of the world’s second-tallest structure when it opens in June 2023, these projects will captivate city dwellers for years to come.

Even as these new monumental buildings rise, China’s prominence in the world of skyscrapers—with three cities in the top five globally—is likely to remain unchallenged.
