The structural correlates of metropolitan migration: 1970-1975

This study is concerned with the debate over the supremacy of organizational versus environmental models for explaining population change within the context of metropolitan-nonmetropolitan turnaround migration. A sample of U.S. metropolitan areas is classified by a migration typology that considers sign changes or consistencies in rates of net migration between the 1960s and 1970s. "Four categories result and organizational, environmental and technological data are analyzed utilizing ridge regression with interaction terms to ascertain whether structural differences among migration categories exist." The study shows that organizational factors are more relevant for urban areas experiencing in-migration, and environmental factors are more relevant for those experiencing out-migration.
