Determinants of 1980 to 1990 Net Migration in Texas Counties: The Role of Sustenance Specialization and Dominance in International Ecosystems

Abstract

Abstract Patterns of 1980–1990 migration differ markedly from those of the 1970s but they have received little conceptual or empirical analysis because of limited data and because their diversity has resisted theoretical generalization. An expanded human ecological perspective incorporating international dimensions is hypothesized to explain differentials in migration during the 1980s. Counties with key functions which operate in international ecosystems in which the United States is dominant are hypothesized to control more resources and to have the highest net inmigration. Hypotheses are tested using regression analyses of 1980–1990 net migration for Texas' 254 counties. The results generally confirm that key functional activities were related to migration but less so in nonmetropolitan areas. Implications for rural development and for further research are discussed.
