Number 2 on the list of most populous islands is Japan. It has a population of 140 million, making it the most populous island in the world. The island of Java in Indonesia, shown on the left, is also about the same size as New York State. There is a good chance you’ve never even heard of these cities, yet the area is home to over 100 million people. Nearly half (46%) of the world’s population lives within just the area shown in this image.Īnd unlike the rest of the world, much of the population is concentrated deeply inland. The Chengdu / Chengking region, the large yellow blob in the center of China, is about the same size as the state of New York. The bulk of the yellow region is clearly located in India, Bangladesh, and China. If you’d like to take a closer look, you can download a high resolution version from here.īelow are the zoomed-in views of a few select areas. Not all of the details are visible in the map at the top. population projections, 2015-2100 A higher resolution view By that time, the populations of Asia, Europe, and the Americas will be flat or shrinking.

Nearly all of the world’s population growth by 2100 will occur in Africa. Particularly in Africa, where nearly all of the population growth is expected to occur, there is an abundance of open space for more people to live. In terms of area, the black region covers 99% of the Earth’s land. Judging by this map, the answer is a clear yes. While overpopulation may be a localized problem in some of the densely population areas of Asia (see population maps of Bangladesh/India and Tokyo), the vast majority of the world’s land area is actually very sparsely populated. Looked at in isolation, that number seems astoundingly high.ĭoes the earth have enough room to accommodate so many people? Plenty of open spaceĪs discussed in a previous post, by 2100, the world’s population is projected to balloon to 11 billion.

In total, the world’s population is evenly split between the two areas, half living in the yellow and half living in the black. In other terms, the population density throughout the black area is less than 900 people per square mile. Conversely, the black region is made up of those cells with populations of less than 8,000 people.

Since each of them has an area of about 9 square miles, the population density of each yellow cell is at least 900 people per square mile, roughly the same population density as the state of Massachusetts.

The yellow region in the map includes every cell with a population of 8,000 or more people.

The population grid used here comprises 28 million cells, each one measuring roughly 3 miles x 3 miles. Whereas populations are typically broken down by geographic regions such as countries or states, gridded population data divides the world population into a grid of tiny square-shaped cells, without regard for administrative borders. This map was created using gridded population data compiled by NASA. Half the world’s population lives in the yellow.
