The future of the world’s population in 4 charts | Open Data

Last week, the UN released updated population figures and projections.
How accurate are these projections? What kind of track record do UN demographers have? The most comprehensive answer I could find was Nico Keilman’s 2001 paper which Hans Rosling refers to in this video. He notes that in 1958, when the UN projected the population in 2000 to be ~6 Billion (it was then 42 years into the future) they ended up being out by less than 5%. The short answer is: these projections are pretty good.
OK, back to the new data released in 2015: here are some of the trends that stand out for me. Note that I’m using the UN’s regional groupings rather than the World Bank’s.
