I love the world. No, not in some tree hugging, Michael Jackson sorta way, but because it’s so damn interesting. So many stories entwined into one long, tragic but glorious tale: and nothing shares it quite like a map.
Thanks to the painstaking work of the guys at the Correlates of War Project, I managed to obtain country religion data  at the click of a button. From there, it’s a breeze to find the main religion and map its dominance using CartoDB. Here it is:
Cool huh? Just a glimpse tells a story of empire, conquest and isolationism. A few interesting insights:
- The monopoly of Christianity in the New World is alarming. It’s obvious who won the race there.
- Japan looks all adorable and lonely over in the East due to its historical isolationism.
- The conquests of the Mohammedans in the 6th and 7th century were vast, and when nations become Islamic, they stay Islamic.
- The influence of China over the North and the USA over the South are obvious on the Korean Peninsula.
Also it’s worth a quick mention of the limitations of the data set:
- Generally each country was surveyed in a different study, and hence the results will differ in their reliability.
- Following a religion will mean different things to different countries and cultures. To some it may mean being pious, whereas others it is just a source of identity. For example religion seems to be very prominent in the Nordic countries, but in reality this isn’t true in the traditional sense.
So take the results with a pinch (or truckload) of salt. Arigato and Sayonara.
