The neighborhoods of cities in the 19th century show how race/ethnicity and economic status are divisive forces in how people live.  The income maps that were given show how although there are subtle differences in income within some neighborhoods, there they are pretty much at the same income level, with no real high income people nor poverty-stricken people near them.  And when compared to the race/ethnicity maps, the neighborhoods line up quite well, with the income and racial divisions almost being at the same place.  

Because of the massive amounts of people that were moving to urban areas in the 19th century, especially immigrants moving into low income housing, there was low amounts of public space to go out and meet other ethnicities.  This is why many ethnicities then kept to themselves, and true mixing only occured where it just happened to occur, like where one group has to walk past another to get to their own neighborhood.
