Characterizing dynamic spatial and temporal residential density patterns from 1940-1990 across the North Central United States

摘要: The spatial deconcentration of population during the 20th century and resulting expansion human settlements has been a significant cause anthropogenic landscape change in United States many other countries. In seven-state North Central Region, as regions US, changing settlement patterns are most prominent at outlying fringe metropolitan areas rural with attractive recreational aesthetic amenities. This process growth profound implications for ecology region that will require reformulation resource management policies. We use attribute clustering both housing density each decade from 1940 to 1990 illuminate dynamic Region. While cross-sectional maps display uniformity residential within urban, suburban, areas, historic demonstrates variability trajectories urban suburban relative stability homogeneity more trajectories. Clusters based on growth, without regard absolute density, reveal similarities between cores where cases, very slow recent decades. identify density/growth clusters high potential future which spatially clustered periphery smaller centers, throughout region.
