UN Adopts Equal Earth Map to Correct Africa's Size Distortion on Mercator

The United Nations General Assembly has voted to replace the Mercator map—the projection that has dominated classrooms, atlases, and digital platforms for more than four and a half centuries—with the Equal Earth projection, a cartographic choice that amounts to a quiet statement about how the world sees itself.

The problem the UN sought to address is stark and visual. On the Mercator map, Africa appears roughly the same size as Greenland. In reality, Africa is about fourteen times larger. This distortion is not accidental or minor. It is the inevitable result of trying to flatten a sphere onto a rectangle, a mathematical problem that has no perfect solution. When Gerardus Mercator, a Flemish cartographer, created his projection in 1569, he was solving for a specific need: he wanted sailors to be able to draw a straight line on his map and follow it as a constant compass bearing across the ocean. The map worked brilliantly for that purpose. To achieve it, Mercator had to stretch the grid lines wider as they moved toward the poles, which meant landmasses near the equator shrank while those near the poles swelled. Four centuries later, that same map underlies Google Maps, appears in countless textbooks, and shapes how billions of people mentally organize the world.

But there is a cost to this visual hierarchy that goes beyond geography. Kioko Muendo, a Kenyan geographer, frames it plainly: maps are not neutral tools for travelers. They are instruments of perception. When a region appears smaller on the map you see every day, it registers as less significant—less resourced, less populated, less worthy of investment or attention. For Africa, a continent that has been systematically misrepresented in Western cartography for centuries, the Mercator projection has reinforced a psychological diminishment that persists in how the continent is understood politically and economically.

The Equal Earth projection, adopted by the African Union in February and now endorsed by the UN, attempts to correct this. Developed by a team of cartographers in 2018 and inspired by the Robinson projection from 1963, it presents landmasses in their true proportional sizes. Africa appears as large as it actually is. But this correction comes with its own sacrifice. The Equal Earth map abandons the straight lines that made Mercator perfect for navigation. A sailor cannot use it to plot a course. Distance measurements become unreliable. As James Cheshire, a cartography professor at University College London, explains the fundamental constraint: you cannot preserve area, shape, and distance all at once on a flat map. To do so would require the map to be a sphere.

Other alternatives exist, each with their own trade-offs. The Peters map, designed by German historian Arno Peters in the early 1970s, fixes the size problem while maintaining straight lines of latitude and longitude. But it severely distorts shape—Russia appears shrunken, polar regions are compressed, and landmasses look subtly wrong. The Azimuthal equidistant projection, used on the UN flag itself, centers the world on a chosen point and preserves correct distances and directions from that center, though it distorts everything else. Even the south-up map, which simply rotates the traditional north-up orientation by 180 degrees, challenges the assumption that north belongs at the top.

What the UN's adoption of Equal Earth signals is not that cartography has been solved, but that the choice of which distortion to accept is itself a political decision. For more than four centuries, the world accepted Mercator's distortion because it served European navigation and, later, European and American dominance. Now, as that dominance is questioned and as Africa's actual economic and demographic weight becomes harder to ignore, the map is being redrawn. The Equal Earth projection will not appear everywhere overnight. Google Maps will not switch. Textbooks will not be reprinted in a day. But the UN's resolution marks a moment when the institution acknowledged that what we choose to see, and how we choose to see it, matters.
