ABSTRACT
This chapter analyzes the six SEC groups more closely in terms of how they differ in size, density, land uses, employment bases, design features, and various measures of workforce mobility. It presents a combination of statistical tests and summary graphs. Most of the tests compare differences in mean values of variables across the six SEC groups, using the method of Analysis of Variance (ANOVA). The chapter uses SEC groups as the lense for exploring transportation-land use relationships while its successor concentrates on how specific land use variables influence workers' commuting choices and local traffic conditions. Since land use was another variable used to discriminate between groups when clustering SEC cases together, differences in land use mixtures can certainly be expected among groups. The chapter discusses the magnitude of these differences, concentrating on the relationship between office, retail, and housing components among SEC classes.
