Maps shape our understanding of the world – and in an increasingly interconnected and global economy, this geographic knowledge is more important than ever.
The funny thing is, almost everyone actually has a skewed perception of the true size of countries thanks to a cartographic technique called the Mercator projection. Used just about everywhere, from textbooks to Google Maps, the Mercator projection map is the way most of humanity recognizes the position and size of Earth’s continents.
The Mercator Projection
In 1569, the great cartographer, Gerardus Mercator, created a revolutionary new map based on a cylindrical projection. The new map was well-suited to nautical navigation since every line on the sphere is a constant course, or loxodrome. In modern times, this is particularly useful since the Earth can be depicted as seamless in online mapping applications.
That said, the true sizes of landmasses become increasingly distorted the further away from the equator they get. Mercator’s map inadvertently pumps up the sizes of Europe and North America. Visually speaking, Canada and Russia appear to take up approximately 25% of the Earth’s landmass, when in reality they occupy a mere 5%. When Antarctica is excluded (as it often is), Canada and Russia’s visual share of landmass jumps to about 40%!
Canada is the second largest country in the world, but not by much. Here is an “at scale” look at Canada, the United States, and Mexico.
Africa, South Asia, and South America all appear much smaller in relation to countries further from the equator.
And from a North American perspective, countries such as Australia and Indonesia appear much smaller than they actually are. Comparing the landmasses on the same latitude as Canada helps put sizes into perspective.
Greenland is the world’s largest island, but looking at its hyper-exaggerated depiction in the map below, you’d be forgiven for wondering why it isn’t a stand-alone continent. In reality, Greenland is about fourteen times smaller than Africa.
Is Bigger Better?
Though Mercator’s map was never intended for use as the default wall map in schools around the world, it has shaped the worldviews of billions of people. Critics of the map – and similar projections – suggest that distortion reinforces a sense of colonialist superiority. As well, the amount of territory a country occupies is often correlated with power and access to natural resources, and map distortions can have the effect of inadvertently diminishing nations closer to the equator.
A prime example of this argument is the “True Size of Africa” graphic, which demonstrated to millions of people just how big the continent is.
Growing awareness of map distortion is translating into concrete change. Boston public schools, for example, recently switched to the Gall-Peters projection, which more accurately depicts the true size of landmasses.
In our society we unconsciously equate size with importance and even power.

The Road to Equal-Area Mapping
In 1805, mathematician and astronomer, Karl Mollweide, created a namesake projection that trades accuracy of angles and shape for accuracy of proportion. The Mollweide projection has inspired many other attempts at a user-friendly equal area map.
John Paul Goode’s attempt, known as the Goode Homolosine Projection, took this concept a step further by adding interruptions at strategic locations to help reduce the distortion of continents. The resulting shape is sometimes referred to as an “orange peel map”.
Another evolution in cartography was the Dymaxion map, invented by Buckminster Fuller and patented in 1946. In this version, the continents are no longer in their familiar positions – however, there is more spacial fidelity than in previous projection methods. We’re able to see the true proportions of Africa, Northern Canada, Antarctica, and other distortion hot spots.
The Dymaxion map wasn’t created for purely practical purposes. Fuller believed that humans would be better equipped to address global challenges if they were given a way to visualize the Earth’s continents in a contiguous manner.
The AuthaGraph Map
Using a new map-making method called AuthaGraph, Japanese architect, Hajime Narukawa, may have created the most accurate map of the world yet. AuthaGraph divides the globe into 96 triangles, transfers them to a tetrahedron and unfolds into a rectangle.
The end result? Landmasses and seas are more accurately proportioned than in traditional projections.
The biggest downfall of the AuthaGraph map is that longitude and latitude lines are no longer a tidy grid. As well, continents on the map are repositioned in a way that will be unfamiliar to a population that is already geographically challenged.
That said, depicting our round world on a flat surface will always come with some trade-offs. As demand grows for a true equal-area map, it will be exciting to see what the next generation of map projections have to offer.
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.
How Much Student Debt Does Each State Hold?
Crippling student debt in the U.S. has reached a record high of $1.5 trillion nationwide. Today’s map breaks down which states bear the highest burden.
How Much Student Debt Does Each State Hold?
Education may be priceless, but the costs of obtaining it are becoming steeper by the day.
Almost half of all university-educated Americans rely on loans to pay for their higher education, with very few graduating debt-free. Total U.S. student debt has more than doubled in the last decade—reaching a record high of $1.5 trillion today.
Today’s data visualization from HowMuch.net breaks down the average student debt per capita, to uncover which states shoulder the highest burden in this growing crisis.
Students are Paying Through the Nose
Before diving into the graphic, let’s take a quick look at why student debt is racking up. The ballooning costs to attend college today compared to thirty years ago is one driving factor.

What’s more, these figures don’t include the expenses for accommodation and other supplies, which can add another $15,000-$17,000 per year.
The United States of Student Debt
In the state map above, it’s immediately obvious that Washington D.C. tops the list. While the nation’s capital is the most educated metropolitan area in the country, it also suffers from $13,320 in student debt per capita.
At approximately 147% above than the national average of $5,390, Washington D.C.’s debt burden per capita is almost double that of the state in second place. Georgia comes in with $7,250 debt per capita, 34.5% above the national average.
|State||Student Debt per Capita||Difference from Average|
|District Of Columbia||$13,320||147.1%|
Rounding out the five states with the most student debt per capita are Maryland, Minnesota, and Ohio, in that order. On the flip side, Wyoming has the least debt per capita ($3,610), which is 33.0% lower than the national average. Hawaii follows right behind at $3,780, and 29.9% below the national average.
Interestingly, a growing population on the West Coast helps to lower the debt burden for states like California, even despite the strong presence of prestigious schools. Home to Stanford, USC, UCLA, CalTech, and more, the Golden State surprisingly only has $4,530 in debt per capita.
The Last Straw?
Today’s Americans are more educated than ever before, but the sticker shock is causing some whiplash. This overall trend of spiraling student debt has significant implications on a person’s life trajectory. With many graduates unable to repay their loans on time, more of them are delaying major life milestones, such as starting a family or becoming a homeowner.
In efforts to curb this crisis, many 2020 presidential hopefuls have already started proposing plans to cancel or forgive student debt—with close attention on mid- to low-income households that would benefit the most from reduced loans.
