Residential segregation separates people by race, class, and/or income and results in a multitude of problems, many of which are now only too well known.  Poor people are geographically concentrated in particular areas of the city largely because that is where affordable housing is available.  One major reason why traditional high-rise public housing has failed in the US is because of the exclusive concentration of poor people in small areas.  Low-income areas of the city generally have lower than average police protection, few municipal services, inadequate maintenance of buildings and infrastructure, and very few employment opportunities.  There is now a large literature that suggests that areas with mixed-income housing have fewer such problems.  With that in mind, in the summer of 2002, I looked at several small housing arrangements in the Belmont-Mantua area of West Philadelphia.  The data I collected relates to housing, income, and experiences and perceptions of poverty in two apartment complexes owned and managed by a Quaker-run organization called the Friends Rehabilitation Program. My still preliminary analysis of the data suggests that the range of incomes I encountered among the apartment residents was not wide enough to produce the kind of benefits of mixed-income housing that are reported in recent literature.
