SELF-SELBCTION AND INTE8NAL MIGRATION IN THE uNITED STATESGeorge~. Borjas, Stephen G. Bronars, and Stephen J. Tr&jo
Executive summarvThe population of the United States is highly mobile. Since the 1960s, aPPrOxi=tely three percent of the population moves across state lines in any given yea:, and 10 percent of the population moves across state lines in a five-year period. In view of-the falling fertility rates of American women, this extensive mobility implies that migration has become an increasingly important source of demographic change in the various regions . .and a msjor determinant of concurrent changes in regional economic growth.Internal migration rates are especially high among the young. ,, In the . National Longitudinal Survey of Youth, over half of the sample are currently (i.e., in 1986) residing in a state other than their state of birth, and about 40 percent are living in a different state than they were at age 14" (see Table 1). The data also indicate that approximately 8 percent of white young men and 6 percent of black and Hispanic young men move across state boundaries in any given year. Our study_presents a theoretical and empirical=analysis of the internal migration of young workers in the United States.Guided by income-maximizing models, previous research has focused on 'explaining" the size and direction of migration flows across areas.Generally, these studies conclude that persons migrate from low-income regions to high-...
