title: Variations in interstate migration of men across the early stages of the life cycle.
abstract: The results reported here show that the stage of an individual's life cycle not only has direct effects on the likelihood of migration, but also establishes a context within which the motives to migrate are evaluated and acted upon. One contextual impact of the life cycle concerns the effects of length of residence on migration. The results show that the probability of migrating declines more rapidly over time for married males with children than for singles males--i.e., the difference between the likelihood of migration for single males and married males with children widens with increasing length of residence. Much of this difference may be due to the greater number and strength of community ties for individuals who are married with children. These ties are not well developed at the beginning of a residence but continue to strengthen over the course of a residence. In addition, there are variations in the levels of job rewards and location-specific resources across the life cycle and there are two variations across the early life cycle in the effects of independent variables on the initial rate of migration. One resource (self-employment) and one job reward (prestige) have different effects for single individuals than for either group of married males. If the span of the life cycle considered in this analysis were broadened to include older men, additional differences in the effects of independent variables might be uncovered. In research with cross-sectional data containing a wider range of ages than the data used here, Heaton et al. (1981) found that economic variables were more important in determining the migration of younger individuals than that of older individuals, whereas noneconomic factors were more important determinants of the migration of older than of younger individuals. The results of this paper and Heaton's results suggest that at different stages of life people use a somewhat different "subjective cost-benefit calculus" in making migration decisions. The importance of certain migration determinants may vary significantly depending on whether an individual is married, whether he or she has children, and/or whether he or she is in the labor force or retired. Additional research on these issues could greatly contribute to our understanding of migration.
