| Abstract: | The macro-level activity spaces of residents in Atlanta, Boston, Cleveland, Denver, Kansas City, and San Francisco differ significantly in areal extent, compactness and shape. They fail to conform closely with the pattern expected based on gravity formulations of distance to and size of potential destinations. Activity space is defined as the percentage of respondents in each city who have visited thirty other metro areas within a decade. Maps of residuals from regression indicate that the major visitation flows from each city are neither random nor concentric but spatially concentrated and easily identified. Macro-level activity spaces may be useful in understanding interregional migration flow bias. |
