Lee at Roving Bandit (probably the best economics blog in Southern Sudan) pointed me to this wonderful heat map of population density in Africa. Click the picture to see maps from other decades going back to 1960.
I went to DC’s Eastern Market today and stumbled upon this map of Africa from 1875 (just a few years before the scramble). I don’t know much about it, other than the date and that it was printed in the US (at the bottom the longitude is given relative to Washington) by Ivison, Blakeman, Taylor & Co. Sorry that the scan is blurry on the sides, my little all-in-one scanner can’t fit the page and I don’t want to bend it.
