Professor Frieden has provided planners with a valuable tool for analyzing the strength of a metropolitan population's preference for a central residential location. This is a significant contribution, since important decisions involving millions of dollars must or at least should be based on this preference. In illustrating his methodology, however, Frieden commits two errors: he uses a single, atypical sample to represent an entire area, and he fails to take an important factor, the amenity level, into account. As suggested in this paper, these errors of analysis could possibly lead to seriously mistaken decisions, so it is suggested that Frieden's conceptual scheme be modified to employ some form of multivariate analysis. Further, it is urged that extreme care be given to the selection of the sample upon which the analysis is based. With these modifications, studies similar to Frieden's pioneering efforts should provide city and regional planners with many valuable insights into the complex patterns of relationships found in our metropolitan areas.
