Mapped: The True Size of Africa

Take a look at any map, and it’s clear that the African continent is a big place.

However, despite the common perception that Africa is a large landmass, it’s still one that is vastly underestimated by most casual map viewers.

The reason for this is that the familiar Mercator map projection tends to distort our geographical view of the world in a crucial way — one that often leads to misconceptions about the relative sizes of both countries and continents.

A Geographical Jigsaw

Today’s infographic comes from Kai Krause and it shows the true size of Africa, as revealed by the borders of the countries that can fit within the continent’s shape.

The African continent has a land area of 30.37 million sq km (11.7 million sq mi) — enough to fit in the U.S., China, India, Japan, Mexico, and many European nations, combined.

You could add together all of the landmasses above and they would not equate to the geographical footprint of Africa, which itself is home to 54 countries and 1.2 billion people.

Editor’s note: The above table is slightly different from the countries shown in the visualization, which focuses more on fitting recognizable country shapes into the geographical shape of Africa.

Why the Misconception?

Interestingly, the problem with maps is not that Africa is sized incorrectly.

Using the animation below, you’ll see that Africa is actually the most accurately sized continent using the common Mercator map projection:

True size of countries animation Mercator

The Mercator projection attempts to place the spherical shape of the world onto a cylinder, causing areas closest to the poles to be “stretched”.

Africa, which straddles the Equator, barely changes in size — meanwhile, the countries furthest from the Equator become inflated from their true sizes on this type of map.

Mercator cylindrical projection

For those of us living in Western countries, this is an interesting dilemma to consider.

This means that the sizes of European and North American countries are distorted, giving us an inaccurate mental “measuring stick” for judging the relative sizes of other countries.

This has implications not only for Africa, but for the whole Southern Hemisphere: South America, India, the Middle East, and even Australia are “bigger” than they may initially appear on a map.

Visualizing the Average Lifespans of Mammals

While smaller animals such as weasels typically live 1-2 years, larger counterparts can thrive for decades.

Mammals, though comprising a small fraction of Earth’s creatures, hold vital ecological roles globally. They are crucial for maintaining ecosystem health through services like pollination, seed dispersal, and predator-prey dynamics.

In this visualization, we depict the average lifespans of mammals, using data from Discover Wildlife and the United Nations.

Human Lifespans on the Rise

Defined as warm-blooded creatures with hair or fur, mammals nurse their young with milk from mammary glands. While smaller animals such as weasels typically live 1-2 years, larger counterparts like elephants can thrive for decades, and bowhead whales can live for 200 years, or even longer.

Notably, human lifespans have experienced a remarkable surge. According to the UN Population Division, the global average life expectancy has surged from 47 years in 1950 to 72 years in 2022, marking a 25-year increase. This is attributed to advancements in nutrition, medication, and essential resources.

However, as human longevity flourishes, it can have an adverse effect on wildlife mammal populations. To put this into numbers, over the past 100,000 years, the surge in human population has precipitated an 85% reduction in wild mammal biomass.

Today, livestock dominates 62% of the world’s mammal biomass, with humans accounting for 34%, while wild mammals comprise only 4%.

Despite a decline in mammal diversity, the total biomass of terrestrial mammals has significantly increased, expanding approximately ninefold over the past 10,000 years.
