Chicago has always been a diverse city, being composed of people from all around the world, however it's also got a nasty reputation for being ethnically segregated. And as the decades have progressed, enclaves of ethnic groups have shifted or in some cases disappeared. This map commissioned by city's Department of Development and Planning in 1976 draws out the city's neighborhoods and details the settlement patterns of its residents. It's interesting to see how much has changed in the last 65 years, but yet at the same time how much certain areas still remain very similar to the way they were back in the '50s.
