Black population on inner South Side and moving into the West Side too. Jewish population still on West Side (Lawndale) but now moving in a northerly direction and newer concentrations on the North Side emerging. Italian population seems to be mostly on the West Side. The Polish near NW (still extant today due to immigration) is evident. The rest of the city looks pretty mixed up in terms of European nationalities.
