"At the aggregate level, return migrants in Puerto Rico in 1970 and 1980 faced greater employment-related difficulties, as compared with nonmigrants. This article explores the individual-level relationship of return migrant status to employment outcomes. The conceptual framework takes into consideration local and regional contextual factors, particularly the employment conditions prevailing in Puerto Rico during this period. Within this framework, specific hypotheses suggest a negative influence of return migrant status.... The findings substantiate the hypotheses for both census years and indicate the importance of the duration of residence in the United States and the timing of the return move as mediating factors."
