This map shows how the population of the world is distributed. It uses a typographic visualization technique – FatFonts –which allows you to read the exact number of people living in a particular area with a precision within 100,000 people. Each number in the world map corresponds to the population in an area of approx.. 40,000 km².

FatFonts are digits that can be read as numbers, but also encode the information visually in the amount of ink that each digit uses. For example, digit eight 8 has eight times the amount of ink of digit one 1, digit seven 7 seven times and so on and so forth. This technique turns a table of numbers into a graphical representation where darker areas (with thicker numbers) represent higher population density. Step back to get an overview of which areas are heavily populated, come closer and you can read the exact values.

To represent population densities from the tens of millions in a square (e.g., in New York City or Istanbul) to the hundreds of thousands, we use two layers: the FatFont numbers with orange backgrounds represent tens of millions of people. For example, the square that contains Buenos Aires shows you that fourteen million people live in that square of the world (the smaller 4 within the larger 1 represents the smaller order of magnitude). Tiles without an orange background represent populations between 9.9 million people to 100,000 (one order of magnitude lower).

The map uses an equal-area projection; the numbers that you read are, therefore, also population densities. The representation is derived from the 2005 estimations for 2015 of the GPWFE dataset made available by SEDAC, Columbia University. 15 insets highlight interesting areas of high and low population in more detail, such as Northern China, Mexico City, Egypt, Western Japan, Bangladesh and Africa’s Great Lakes region.
