The World's Population Pyramids


Earlier this year The Pudding created an impressive interactive map which visualized the world's population in 3D. The Pudding's Human Terrain interactive map shows population density across the globe using 3D population pyramids. The taller a pyramid block on The Pudding map then the more people live there.

The Pudding has now used its own map to explore in more detail the pattern of population density around the world. In Population Mountains The Pudding examines how unevenly the world is populated and how population density can take different forms in different parts of the world.

For example The Pudding compares the pyramid population maps of some European cities to Kinshasa, DRC. In Kinshasa poor transportation infrastructure has led to a densely populated city center, whereas European cities tend to have less densely populated centers and more densely populated suburbs. Because of poor transportation in Kinshasa the population pyramids in the city center fall sharply away, while in European cities there tends to be a more gradual slope from the center away into the suburbs.

If you don't like The Pudding's 3D visualization of the world's population then you might prefer the SEDAC Population Estimator (GPWv4). This interactive map uses NASA's Earth Observing System Data and Information System (EOSDIS) data to show where the world's population lives. The SEDAC Population Estimator map includes a tool to draw an area on the map to view an estimate of the population that live there.
