Map Shows Population Density
As Planet Reaches 7 Billion People
With the world’s population now surpassing 7 billion
, a Boston-based design firm has published a map illustrating the planet’s population density, including detailed visualizations of the most densely populated cities. Dencity, which was created by Fathom Information Design
, uses circles of various sizes and hues to represent population density, with larger, darker circles showing areas with fewer people, and smaller, lighter circles representing the world’s most crowded cities and regions. China — home of eight of the world’s 20 most populated cities — contains a series of tightly packed orange and yellow dots. Likewise, the populous nations of India and Pakistan are almost uniformly dense until they reach political boundaries or geographic features, such as the Himalayas. Meanwhile, the larger, darkly hued dots illustrate the less-populated areas of the world, including Saharan Africa and Siberia.
