The Fastest Growing Cities in the World (2000-2016)

Published

on

Thanks to drastic increases in crop yields and the falling need for manual farm labor, a mass migration towards cities started in the years following the Industrial Revolution.

This phenomenon first originated in developed economies as people moved to work in factories that produced consumer goods at a scale never before seen. Then in the 1950s, developing economies started to follow suit.

The results have been staggering, and today a country like China has at least 35 massive cities that each have an economic output comparable to entire countries.

Urban vs Rural growth

After many decades of urbanization, the portion of people living in urban areas has surpassed the total rural population. This happened in 2007, and we are now in the first window in human history in which more people are city dwellers.

So what cities are the meccas for urban migration today? And which are falling out of favor?

The Fastest Growing Cities (2000-2016)

The following interactive and zoomable map was put together by Datawrapper, using data from the United Nations.

It lists 500 cities with over 1 million people, and is shaded based on annualized population growth rate between 2000 and 2016. Percent growth corresponds with darker shades of teal, while orange symbolizes negative growth over the timeframe.

It’s strongly recommended to explore the map by zooming in on particular regions. Highlighting cities themselves will give you population details for 2000 and 2016, as well as an annualized percentage growth rate.

Here are some areas we thought were worth looking at in more detail:

North America
North America is mostly what one may expect. The biggest cities (NYC, LA, Chicago, Toronto) aren’t changing too fast, while some cities in the Rust Belt (Detroit, Cleveland, Pittsburgh) have slightly negative growth rates. Austin, TX and Charlotte, NC seem to be the fastest growing cities in the U.S., overall.

South America
Colombia’s Bogotá stands out as the city in South America growing at the most blistering pace. It gained 3.6 million people in the 2000-2016 year period, good for a 2.8% annual growth rate.

China and India
These two populous countries are home to many of the dark-shaded circles on the map. It’s worth looking at an additional screenshot here (just in case if you haven’t zoomed in above).

China and India cities

Look at the coast of China – it’s dotted with rapidly expanding cities. Incredibly, in the 16-year span of data, some of these cities have doubled in terms of population. Others like Xiamen have tripled in size. Shanghai alone has gained 10.5 million people in this span of time.

In India, the fastest growing cities are in the south, where there are at least 10 large cities that have roughly doubled in size. Delhi, which is in the north, has added nearly 11 million inhabitants over the same stretch.

Africa
In Africa, we see the names of many of the cities that are projected to be the world’s largest megacities by 2100.

Lagos in Nigeria has doubled to nearly 14 million people between 2000-2016, and it is expected to explode to 88.3 million people by 2100 to be the world’s most populous city overall. Dar es Salaam (Tanzania) and Kinshasa (DRC) are two other places that are set to grow rapidly by 2100, rounding out the list of the world’s three most populous megacities.

Visualizing the World’s Top Plastic Emitting Rivers

Every year, 8 million metric tons of plastic enters the world’s oceans – much of it through our river systems. See which rivers are polluting the most.

Visualizing the World’s Top Plastic Emitting Rivers

Every year, approximately eight million metric tons of plastic enters the world’s oceans – the equivalent of one garbage truck of plastic every single minute.

Every plastic fork and bottle cap bobbing along the surface of the ocean has made its way to the ocean from dry land at some point. As it turns out, the hydrological cycle that keeps water circulating around the planet is also an effective means for trash to hitch a ride from our riverside cities to the open ocean.

As today’s unique, vintage-themed map – via John Nelson at ESRI – visualizes the shocking amount of plastic emitted by major rivers in the world.

Plastic Superhighways

It would be hard to overstate plastic’s influence on modern life.

Unfortunately, when plastic is finished doing it’s job, only 10% of it ends up being recycled. Instead, much of the 300 million tonnes of plastic produced each year ends up in the ocean, congregating in places like the Pacific Garbage Patch.

Plastic discharge is especially pronounced in large population centers along large rivers – particularly in rapidly urbanizing regions in China, Indonesia, and Nigeria.

River plastic emissions to the world’s oceans

Waste management practices are limited to non-existent in many of Asia’s fast-growing urban areas, so it comes as little surprise that 14 to the top 20 plastic emitting rivers are located on that continent.

The mighty Yangtze – China’s largest river – supports a population of over 400 million people and is the most prolific emitter of plastic waste on the planet. Over 1.5 million metric tons of plastic is unleashed into the Yellow Sea from the river each year.

Stemming the Tide

Plastic emissions data makes one point clear – China is the key to decreasing the volume of trash entering our ocean ecosystems.

The good news is that the Chinese government has recognized the problem, mandating garbage sorting in nearly 50 cities and setting a target for at 35% recycling rate by 2020. A positive first step in the battle to stem the tide of plastic entering ocean systems.

Upward Momentum: Charting a Year of Skyscraper Construction

Nearly 150 skyscrapers were completed around the world last year. Find out which cities and regions are growing skyward the fastest.

Published

on

Ever since the first towering spires broke through the clouds in New York and Chicago, skyscrapers have remained a potent symbol of economic might.

The tallest buildings require vast amounts of materials, expertise, and capital to make them a reality, but the cities that add these landmarks to their skylines gain prestige and send a powerful message to competing economic centers.

Skyscraper Construction in 2018

Where are the most skyscrapers popping up? Let’s take a look at regional hot-spots around the world.

Charting a Year of Skyscraper Construction
Note: For the purposes of this article, “skyscraper” will refer to buildings 656 feet (200 meters) or more in height.

China is Flying High

For well over two decades, China has led the world in skyscraper construction, and 2018 was no exception.

The country’s fixation on urban growth and continued economic success is producing tall buildings at a staggering rate. Last year, a mind-boggling 89 skyscrapers were completed in 28 different cities around China.

To put this building boom into perspective, China completed more skyscrapers in one year than New York City’s entire stock of 656ft and taller buildings.

Skyscrapers in China

In 2018, no city reached for the stars quite like Shenzhen. The city, which is a hub of China’s high-flying tech sector, now has the second-most skyscrapers in the world, surpassed only by Dubai.

Shenzhen isn’t just building a lot of skyscrapers, it’s building extremely tall ones too.

In 2017, for example, the ribbon was cut on the massive Ping An Finance Center, which is currently the 4th tallest building in the world. Last year alone, four new towers cracked the 1,000ft (300m) barrier.

Asia, Rising

While China’s scale is hard to beat, other cities in the region are also undergoing dramatic changes, particularly in Southeast Asia. Malaysia and Indonesia completed a combined 13 new skyscrapers, and the Vincom Landmark 81 was added to Ho Chi Minh City’s growing roster of unique skyscrapers.

While there are two skyscrapers under construction in Japan – one in Tokyo and one in Yokohama – none of them were completed last year.

A New Era of American Skyscrapers

After a two-decade lull in skyscraper construction, the United States is embracing taller buildings again. Last year alone, the U.S. added 14 new skyscrapers into the mix, particularly in New York City, where construction cranes dot the horizon. In the past decade, NYC has added 25 new skyscrapers to its iconic skyline.

This trend is showing no signs of slowing down. Between now and 2022, 44 skyscraper projects are expected to be completed in the United States, with the vast majority being built in the Big Apple.
