After the 1870 census, cartographers and researchers analyzed the data and created some spectacular infographics with nothing but pen and paper.  Available on record in the Library of Congress, Radical Cartography has published the spectacular compilation of graphics on their website for viewing in JPEG format.  It’s amazing how much they were able to do without the aid of modern computers to crunch the numbers.  Maps, charts, box diagrams, and more.

Unfortunately, the RadicalCartography site is under some pretty heavy load thanks to a link from BoingBoing.net, so I’ve mirrored the low-res versions of the graphics below for you to see.  Enjoy!

These images are BIG, most of them around 1500 x 2000, so those on slow connections or small monitors may want to be careful about which thumbnails they click on. Radical Cartography has ZIP files for download
