Population redistribution within U.S. suburban rings between 1970 and 1975 was characterized by frequent population declines for individual suburbs. On the whole, recent spatial patterns of suburban population decline are similar in nature, if not overall levels, to those found in the 1950s and 1960s. Population decline is greatest in the inner suburbs, and is also evident, to some extent, in the most peripheral suburbs. Patterns for all metropolitan areas mask clear variation among metropolitan areas. This variation is related to metropolitan age or historical period of development.
