Recent scholarship proposes a “two-step” approach for better understanding mechanisms underlying the migration process, suggesting we study migration aspirations separately from migration behavior and that the one does not always translate directly into the other. Research on aspirations, however, concentrates on the Global South, despite growing migration flows originating in the Global North. Here, we fill this gap, drawing on a nationally representative online survey we commissioned in 2014 in the United States. Bivariate analysis shows that fully one-third of Americans surveyed reveal some aspiration to live abroad, a plurality of those primarily for the purpose of exploration. Multivariate analysis suggests that certain elements of cultural and social capital, including the networks Americans have with prior and current US citizen migrants, structure these aspirations, in tandem with strength of national attachment. Further, both cultural and economic aspects of class, alongside race and national attachment, shape where American aspirants envision going and why. While the existing literature addresses the motivations and profile of American migrants already living abroad, ours is the first study to examine Americans’ aspirations prospectively from the point of origin, thereby connecting the literature on Global North migration flows to that on migration aspirations.
