Animation: Global Population by Region From 1950 to 2100

Published

on

According to the most recent projections by the United Nations, the global population will rise from 7.6 billion to 11.2 billion people by 2100.

At this macro level, the global population is growing considerably – but at the micro level, the numbers are all over the map. It’s expected that some countries like Nigeria will see population numbers quadruple by 2100, while other places like China will see a decline by almost 40%.

This raises the question: how different do the regions of the world look in 80 years, in terms of population?

Population by Region (1950-2100)

Today’s animation comes to us from geographer Simon Kuestenmacher who used this U.N. data to show how population by region is expected to change over the coming years.

Animation: Global Population by Region From 1950 to 2100

The chart shows expansive population growth in Asia until about 2060, which is when the regional population will peak at roughly 5.3 billion. At this point, the continent will make up 51% of the global population.

In addition, Africa’s population is projected to continue to boom until 2100, at which point it will come close to passing Asia’s total. As we previously showed you, Africa will also be home to many of the world’s largest cities by this time.

Factors of Influence

Although 83 million people are being added to the global population every year, this population growth differs greatly by region. As a result, it’s worth looking at two major factors to see why this is the case.

The first is the fertility rate, which has obvious implications on population growth. On a global basis, this rate (measured in births per woman) is close to 2.5, and by 2100 it will have dropped to 2.0.

However, as you’ll see in this next chart, which shows projected fertility rates, Africa is the only region that will still have high amounts of child births 30 years from now. This will be one major driver of the continent’s population boom.

The second measure that plays a big role in these projections is life expectancy. For each new person born, how long are they expected to live?

Until recently, the only countries that had a life expectancy that exceeded 80 years were in Western Europe, North America, and Oceania, with the notable exception of Japan. However, in the coming decades, even the world’s least developed countries will all be closing in on that same benchmark:

Life Expectancy in 2100 (Years at birth)
Global fertility in 2050

The Next 30 Years

According to these same estimates, it is expected between 2017-2050 that half of all global population growth will be in just nine countries (in this order): India, Nigeria, DRC, Pakistan, Ethiopia, Tanzania, United States, Uganda, and Indonesia.

Over that duration of time, it’s also projected that the populations of 26 African countries will at least double.

Ranked: The 10 Most Expensive Cities in the World

From Osaka to New York, we look at a global ranking of the 10 most expensive cities, and how those rankings have changed over the last year.

The Most Expensive Cities in the World

Where personal wealth is concerned, there are two sides to every story.

The first of which is the amount of money a person earns, and the other is what they choose to spend their money on. The latter is influenced by the cost of living in the city where they reside—an ever-changing metric that is driven by a wide variety of factors, such as currency, population growth, or external market movements.

Today’s graphic visualizes the findings from the 2020 Worldwide Cost of Living report and uses data from 133 cities to rank the most expensive cities in the world.

Note: Report research was conducted towards the end of 2019, before the COVID-19 outbreak.

Asia Dominates the Ranking

Globally, the cost of living has fallen by an average of 4% over the last year, with much of the movement up and down the ranking being driven by currency fluctuations.

The locations with the highest cost of living are largely split between Europe and Asia. For the second time in the report’s 30-year history, three cities are tied as the top spot—Singapore, Hong Kong, and Osaka.

Osaka is a newcomer to the top spot, climbing four places over the last year to join cost of living heavyweight champions, Singapore and Hong Kong. As Japan’s third-largest city, Osaka is a major financial hub and a breeding ground for emerging startups, with relatively low real estate costs compared to Singapore and Hong Kong.

Three European cities (Paris, Zurich, and Geneva) sit atop the most expensive city rankings, compared to seven cities only 10 years ago. Similarly, 31 of the 37 European cities have seen a decrease in cost of living overall—largely as a result of the Euro or local currencies losing value relative to the U.S. dollar.

Finally, the top 10 is rounded out with two cities from the United States (New York, Los Angeles) and one from Israel (Tel Aviv).

The Cheapest Cities

While East Asia is home to many of the world’s most expensive cities, South Asia hosts the largest grouping of cities with the lowest cost of living.

#122(t)🇮🇳 IndiaNew Delhi421

Source: EIU. New York City is index baseline (score = 100). Ties in index score values are denoted by (t).

Three Indian cities dominate the cheapest cities ranking due to a combination of low wages and high levels of income inequality, preventing any price increases.

Meanwhile, political and economic turmoil is a common denominator among the cheapest cities outside of South Asia. For example, the Syrian Civil War resulted in an economic collapse, leading to high inflation and a downward spiral in value for the Syrian pound.

A Spanner in the Works

The COVID-19 pandemic is estimated to cost the global economy up to $2 trillion in 2020, so while governments attempt to boost the economy, many are concerned about higher inflation rates spreading across the world.

With a recession becoming more likely, uncertainty around real estate prices will heighten for every city, regardless of their cost of living ranking.

As we navigate chaotic and uncertain times, the next cost of living survey could look very different to today—the most important question will be how permanent the damaging effects of the pandemic will be.

Visualizing the Footprint of Highways in American Cities

Highways improved mobility for the average American, ingraining the automobile into the urban fabric of American cities, for better and worse.

The Impact of Highways

Footprint of Highways in American Cities

Visualizing the Footprint of Highways in American Cities

Driving on the open road is a defining feature of the American experience, made possible by coast-to-coast highways. It defined a generation of life and ingrained the automobile into the urban fabric of American cities, for better and worse.

Today’s animations show how highways reshaped the downtown cores of six American cities and created new patterns of urban life. But first, some background information on the creation of the interstate system.

The Interstate Highway System

The U.S. Interstate System was created on June 29, 1956, when Dwight Eisenhower signed the Federal-Aid Highway Act. It would eventually run 46,876 miles, cost $521 billion and take 36 years to complete.

Map of the US Interstate System

From San Diego to Bangor, the interstate highway system connected Americans and opened up the country to commerce and geographic mobility like never before, but for all its benefits, this new transportation network ripped through established patterns of urban and town life, creating a new era of urban development.

The Legacy of Highways: The Suburbs and Inner Cities

The vast geography of continental America helped to entrench personal mobility and freedom into American society. Highways and automobiles accelerated this lifestyle and even changed the shape of entire cities.

According to Prof. Nathaniel Baum-Snow of the University of Toronto, between 1950 and 1990, the population of central cities in the U.S. declined by 17% despite a population growth of 72% in larger metropolitan areas during the same period. Baum-Snow posits that, had the interstate highway system not been built, central cities’ populations would have increased 8%.

Firms followed the workers to the suburbs, but the highways system also created additional benefits for these firms. Cross-country road access freed manufacturing from ports and downtown rail hubs, while allowing economies to operate across larger distances, altering the dynamics of typical urban economies.

Faced with this new reality, inner cities struggled in years to come.

Inner Cities

The introduction of highways created an increase in the supply of land for development through faster commutes to outlying areas. In 1950, half of all jobs were located in central cities. By 1990, less than one-third of urban jobs were located in the core of American cities.

“Not TV or illegal drugs but the automobile has been the chief destroyer of American communities.” Jane Jacobs, Author The Death and Life of Great American Cities

Benefits of new development accrued to the outer areas while the construction of the highways in inner cities displaced largely low-income communities, segregated neighborhoods, increased the amount of air and noise pollution, devalued surrounding properties, and removed access to jobs for those without a car, further concentrating poverty.

Before and After: Six American Cities

A bird’s eye view of six American cities reveals what was and what is now. By overlaying existing highways over the neighborhoods they replaced, it becomes clear how much interstate construction drastically altered America’s urban landscape.

Oakland
Public opposition to the construction of I-980 was so strong that developers abandoned the project in 1971, only to complete it over a decade later.

Miami Highway
The I-95 carved through Miami’s largely black Overtown neighborhood. The construction of a single highway cloverleaf resulted in 20 square blocks being demolished, displacing over 10,000 people in that community.

Providence Highway
The I-95 comprised unconnected segments between 1957 and 1965 through the densest urban areas in a deliberate effort to prevent premature suburbanization and to revitalize the downtown core.

Cincinnati Highway
The I-71 cuts downtown Cincinnati off from its waterfront and a massive freeway interchange forced the destruction of dozens of blocks west of downtown.

Detroit highway construction
Freeway construction transformed Detroit between 1951 and 2010. Previously, its downtown had been surrounded by a high-density street grid. Today, it’s totally encircled by freeways.

Rochester Highway
Rochester is one of many cities opting to undertake freeway removal projects.

As the dotted line above shows, the “moat” surrounding downtown is slowly being removed. The city used reclaimed land from the Inner Loop freeway to construct three mixed-use developments that include below-market-rate units.

The Future of Urban Living: Do Highways Matter?

A new era of living is reconsidering the impacts of these highways on urban centers. As property values rise and existing housing stock is pressured, there are growing concerns over the environmental impacts of suburban life. As a result, urban planners and residents are looking to revitalize city cores and re-purpose land occupied by burdensome slabs of highway concrete.

Since 1987, there have been more than 20 urban highway segments removed from downtown cores, neighborhoods and waterfronts, mostly in North America. The pace of removals has picked up significantly and an additional 10 highways are now planned for removal in the United States.

During the COVID-19 pandemic, American cities have seen their traffic plummet. Rush-hour trips into cities are taking nearly half the time while some are not even commuting at all.

While this situation is likely temporary, it is offering a moment for reflection of how cities operate and whether the car should be at the center of urban planning.
