Modal cities are representative cities based on a specific set of criteria. Using principal components analysis, 224 U.S. SMSA's were examined in terms of 48 selected variables. This analysis yielded 14 dimensions, of which 7 explained 67% of the variance. The 224 cities were then grouped using a method that minimizes the differences among cities within a group and maximizes the differences across groups. This procedure allowed for a confident selection of 9 modalities of the U.S. metropolitan system. Each city fell into a modality and was ranked relative to its distance from the mean. The two cities closest to the mean were taken as representative of that group. One unforeseen result of this research was distinct regional character for the different groupings.
