RELATION BETWEEN RENTS AND INCOMES

of families with telcphoiu" service, in the various areas in any one 

 city. Whether a particular area is suburban or downtown, likewise 

 has no apparent effect on the value oi Q. It was found in Atlanta, 

 where the di\ision of the city into market areas was substantially 

 the same in successiv'e surveys, that the distribution index which had 

 previously been found to be stable for cities as a whole, behaved in 

 the same way in separate sections of the city. It was found that the 

 rent distribution index for any single market area is smaller, usually 

 much smaller, than the index for the entire city in which the area 

 is located. One section in Atlanta is the only exception found to 

 this rule. In market areas it was noted that a considerable number 

 of the graphs on logarithmic probability paper were formed of two 

 intersecting straight lines. This indicates that the sections are not 

 really homogeneous, but contain elements of population radically 

 different in character. This condition can not be obviated by the 

 most careful laying out of section boundaries in case there exists a 

 mixture of families oi essentially different types, as when negro 

 residences are scattered among a predominantly white population.
