The analysis of urban residential patterns performed by Homer Hoyt in the 1930s supplements the work of Ogburn and Harris. According to Hoyt, different types of land use tend to spread outward from the central business district in distinct sectors or wedges of differing social status and economic functions. The growth of such wedges beyond the legal boundaries of a city, of course, brings a variety of land uses into the suburban fringe.

24 It is important to describe more fully how Table 4 and Table 5 were constructed and to examine their limitations. First, the tables display the medians of census tract values and therefore aggregate values of groups rather than of individuals. The propriety of drawing inferences from characteristics or behavior measured at the group or ecological level to the characteristics or behavior of individuals has concerned social scientists for twenty-five years, and the present study makes no attempt to specify the precise linkage relationships. Moreover, all tracts are weighted equally in taking the median values for each zone, although their populations in 1970 varied from 114 to 12,484. Tracts with 1970 populations of less than 100 were omitted from the computations. Second, the census withholds information on the socioeconomic variables for small tracts in order to preserve the anonymity of individuals. Such cases were treated as missing values rather than zero and omitted from the calculation of that particular median. Third, the four zones were defined in terms of 1970 census tract boundaries. In some cases, a single 1960 tract was broken into two or more tracts which fell into different zones in 1970. When this problem arose, the indicator values for the single 1960 tract were counted in the computation of 1960 medians for both zones in which its segments were found in 1970. Fourth, changes of census tract boundaries within Denver mean that Zone 1 for 1940 and Zone 1 for 1950 cover slightly different territories. Fifth, the income ratio in 1950 (Table 5) was computed using an individual level median calculated from Denver, Adams, Arapahoe, and Jefferson County data only.
