Mapped: The Dramatic Global Rise of Urbanization (1950–2020)

The Dramatic Global Rise of Urbanization (1950–2020)

In the 21st century, few trends have matched the economic, environmental, and societal impact of rapid urbanization.

A steady stream of human migration out of the countryside, and into swelling metropolitan centers, has shaken up the world’s power dynamic in just decades.

Today’s eye-catching map via Cristina Poiata from Z Creative Labs looks at 70 years of movement and urban population growth in over 1,800 cities worldwide. Where is the action?

Out of the Farms and Into the Cities

The United Nations cites two intertwined reasons for urbanization: an overall population increase that’s unevenly distributed by region, and an upward trend in people flocking to cities.

Since 1950, the world’s urban population has risen almost six-fold, from 751 million to 4.2 billion in 2018. In North America alone, significant urban growth can be observed in the video for Mexico and the East Coast of the United States as this shift takes place.

Global Urban Population vs Rural

Over the next few decades, the rural population is expected to plateau and eventually decline, while urban growth will continue to shoot up to six billion people and beyond.

The Biggest Urban Hot-Spots

Urban growth is going to happen all across the board.

Rapidly rising populations in megacities and major cities will be significant contributors, but it’s also worth noting that the number of regional to mid-sized cities (500k to 5 million inhabitants) will swell drastically by 2030, becoming more influential economic hubs in the process.

Interestingly, it’s mainly cities across Asia and Africa — some of which Westerners are largely unfamiliar with — that may soon wield enormous influence on the global stage.

It’s expected that over a third of the projected urban growth between now and 2050 will occur in just three countries: India, China, and Nigeria. By 2050, it is projected that India could add 416 million urban dwellers, China 255 million, and Nigeria 189 million.

Urbanization and its Complications

Rapid urbanization isn’t only linked to an inevitable rise in city populations.

Some megacities are actually experiencing population contractions, in part due to the effects of low fertility rates in Asia and Europe. For example, while the Greater Tokyo area contains almost 38 million people today, it’s expected to shrink starting in 2020.

As rapid urbanization continues to shape the global economy, finding ways to provide the right infrastructure and services in cities will be a crucial problem to solve for communities and organizations around the world. How we deal with these issues — or how we don’t — will set the stage for the next act in the modern economic era.

Vintage Viz: World Cities With 1 Million Residents (1800–1930)

From someone born in the 19th century, in the midst of historic population growth, comes this vintage visualization showing world cities growing ever bigger.

World Cities With At Least 1 Million Residents (1800–1930)

This chart is the latest in our Vintage Viz series, which presents historical visualizations along with the context needed to understand them.

The explosive world population boom in the last 300 years is common knowledge today. Much and more has been written about how and why it happened, why it was unusual, and how the specter of a declining population for the first time in three centuries could impact human society.

However, equally compelling, is how people in the past—those living in the midst of the early waves of this boom—were fascinated by what they were witnessing.

Evidence of this comes from today’s vintage visualization, denoting the increasing number of world cities with at least one million inhabitants through the years.

The above pictogram was made by Austrian philosopher and sociologist Otto Neurath (1882–1945), found in his book, Society and Economy, published in 1930.

World Population Doubles Between 1800 and 1930

In 1800, the world population crossed 1 billion for the first time ever.

In the next 130 years, it doubled past 2 billion.

The Second Agricultural Revolution, characterized by massive land and labor productivity, grew agricultural output more than the population and is one of the key drivers of this population growth.

And in the pictogram above, where one silhouette indicates one million inhabitants, this exponential population growth becomes far more vivid.

In 1800, for example, according to the creator’s estimates, only London had at least million residents. A century later, 15 cities now boasted of the same number. Then, three decades hence, 37 cities across the world had one million inhabitants.

190015
193037

Importantly, the data above is based on the creator’s estimates from a century ago, and does not include Beijing (then referred to as Peking in English) in 1800. Historians now agree that the city had more than a million residents, and was the largest city in the world at the time.

Another phenomenon becoming increasingly apparent is growing urbanization—food surplus frees up large sections of the population from agriculture, driving specialization in other skills and trade, in turn leading to congregations in urban centers.

Other visualizations in the same book covered migration, Indigenous peoples, labor, religion, trade, and natural resources, reflecting the creator’s interest in the social life of individuals and their well-being.

Who Was Otto Neurath and What is His Legacy?

This vintage visualization might seem incredibly simple, simplistic even, considering how we map out population data today. But the creator Otto Neurath, and his wife Marie, were pioneers in the field of visual communication.

One of their notable achievements was the creation of the Vienna Method of pictorial statistics, which aimed to represent statistical information in a visually accessible way—the forerunner to modern-day infographics.

The Neuraths believed in using clear and simple visual language to convey complex information to a broad audience, an approach that laid the foundation for modern information design.

They fled Austria during the rise of the Nazi regime and spent their later years in various countries, including the UK. Otto Neurath’s influence on graphic design, visual communication, and the philosophy of language has endured, and his legacy is still recognized in these fields today.
