Victorian London poverty map – from "semi-criminal" to "wealthy"

Leo sends us this "map of the location of the poor people in London in 1889, along with a contemporary map of poverty in London. The most interesting thing is the defintion of the poor classes. The lowest is called: 'Vicious, semi-criminal'."

(Thanks, Leo!)

Update: Andrew sez, "The Economist ran an article on the map Leo sent you this week. Basically, not a lot has changed in the 108 years since it was drawn."
