It’s likely you’re very familiar with the standard world map.
It’s shown practically everywhere – you’ll see it online, on the news, in books, and even as a part of company logos. In fact, the world map is so ubiquitous that we don’t even really think about it much at all, really.
The economist Max Roser from Our World in Data argues that this familiarity with the world map may lead to complacency in understanding global matters. After all, the typical world map shows us the basic geography of countries and continents, but it doesn’t give any indication of where people actually live!
Introducing: The Cartogram
To get around the challenges of relying on the standard world map, Roser instead has made a population cartogram based on 2018 population figures.
What’s a population cartogram?
A cartogram is a visualization in which statistical information is shown in diagrammatic form. In this case, it’s a population cartogram, where each square in the map represents 500,000 people in a country’s population.
In total there are 15,266 squares, representing all 7.633 billion people on the planet.
Countries like Canada or Russia – which have giant land masses but small relative populations – appear much smaller on this kind of map. Meanwhile, a country like Bangladesh grows much bigger, because it has a large population living within a smaller area.
The Regional View
Let’s zoom in on some continental regions to get a sense of what we can learn from a population cartogram done in this fashion.
Asia and Oceania
Where did Australia go? The continent is completely dwarfed by neighboring Indonesia and the Philippines.
Not surprisingly, India and China are the biggest countries on this cartogram, especially looking oversized in comparison to countries in the Middle East like Saudi Arabia, Afghanistan, or the United Arab Emirates.
Geographically, Russia is a pretty massive country – but when resized based on population, the nation looks closer in size to many other European nations.
The Netherlands and Belgium, two countries with higher population densities than most European nations, also appear more prominent on this style of map.
On the map below, Mexico has exploded to almost 4X the size of Canada. That’s because although the Great White North is the world’s second largest country in size, it only has a fraction of the population of Mexico.
Meanwhile, it’s evident that Argentina’s population is lower than the country’s giant landmass leads on.
Finally, we’ll look at Africa, which is in the middle of a massive population boom.
Countries like Namibia, Botswana, and Chad almost disappear.
Nigeria, which is expected to have the world’s largest city by 2100 with over 88 million residents, is the largest country in Africa using this cartogram method.
Mapped: The Dramatic Global Rise of Urbanization (1950–2020)
Few global trends have matched the profound impact of urbanization. Today’s map looks back at 70 years of movement in over 1,800 cities.
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.
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.
Visualizing Over A Century of Global Fertility
Global fertility has almost halved in the past century. Which countries are most resilient, and which have experienced the most dramatic changes over time?
Visualizing Over A Century of World Fertility
In just 50 years, world fertility rates have been cut in half.
This sea change can be attributed to multiple factors, ranging from medical advances to greater gender equity. But generally speaking, as more women gain an education and enter the workforce, they’re delaying motherhood and often having fewer children in the process.
Today’s interactive data visualization was put together by Bo McCready, the Director of Analytics at KIPP Texas. Using numbers from Our World in Data, it depicts the changes in the world’s fertility rate—the average number of children per woman—spanning from the beginning of the 20th century to present day.
A Demographic Decline
The global fertility rate fell from 5.25 children per woman in 1900, to 2.44 children per woman in 2018. The steepest drop in this shift happened in a single decade, from 1970 to 1980.
In the interactive graphic, you’ll see graphs for 200 different countries and political entities showing their total fertility rate (FTR) over time. Here’s a quick summary of the countries with the highest and lowest FTRs, as of 2017:
|Top 10 Countries||Fertility rate||Bottom 10 Countries||Fertility Rate|
|🇳🇪 Niger||7.13||🇹🇼 Taiwan||1.22|
|🇸🇴 Somalia||6.08||🇲🇩 Moldova||1.23|
|🇨🇩 Democratic Republic of Congo||5.92||🇵🇹 Portugal||1.24|
|🇲🇱 Mali||5.88||🇸🇬 Singapore||1.26|
|🇹🇩 Chad||5.75||🇵🇱 Poland||1.29|
|🇦🇴 Angola||5.55||🇬🇷 Greece||1.3|
|🇧🇮 Burundi||5.53||🇰🇷 South Korea||1.33|
|🇺🇬 Uganda||5.41||🇭🇰 Hong Kong||1.34|
|🇳🇬 Nigeria||5.39||🇨🇾 Cyprus||1.34|
|🇬🇲 Gambia||5.29||🇲🇴 Macao||1.36|
At a glance, the countries with the highest fertility are all located in Africa, while several Asian countries end up in the lowest fertility list.
The notable decade of decline in average global fertility can be partially traced back to the actions of the demographic giants China and India. In the 1970s, China’s controversial “one child only” policy and India’s state-led sterilization campaigns caused sharp declines in births for both countries. Though they hold over a quarter of the world’s population today, the effects of these government decisions are still being felt.
Population Plateau, or Cliff?
The overall decline in fertility rates isn’t expected to end anytime soon, and it’s even expected to fall past 2.1 children per woman, which is known as the “replacement rate”. Any fertility below this rate signals fewer new babies than parents, leading to an eventual population decline.
Experts predict that world fertility will further drop from 2.5 to 1.9 children per woman by 2100. This means that global population growth will slow down or possibly even go negative.
Africa will continue to be the only region with significant growth—consistent with the generous fertility rates of Nigeria, the DRC, and Angola. In fact, the continent is expected to house 13 of the world’s largest megacities, as its population expands from 1.3 billion to 4.3 billion by 2100.
