The Geography of AIDS Around the World

Dec 7, 2009

It was World AIDS Day last week and UNAIDS published the latest estimates on the number of people around the world who are living with HIV. Xaquin G.V. provides four cartograms (i.e. value-aread maps) to show the numbers. In the final result (above) each square represents 10,000 people with HIV, and regions are color-coded by percentage of people with the virus.

There shouldn’t be any surprises, really. Africa is in bad shape (although a lot of progress has been made in recent years); North America, Asia, and Europe are below the average average; and the rest are at the world average.

Here are the other cartograms that led to the final. Same data, but different types. There are apparently names for each type.

The Dorling cartogram…

It’s always fun to see the process of making a graphic. People always think that’s just plug in data and go, but it’s more than that – for the customized good stuff at least.
