This paper examines the phenomenon of extreme commuting across the EU among Irish families as one particular response to the economic crisis. Specifically, it looks at Irish couples (married or cohabiting, with or without children) and examines how commuting impacts on family intimacies and dynamics – both for those who leave as well as those left behind. It asks: How is family life lived under conditions where one adult member works overseas? What challenges does this particular family arrangement present? What opportunities? Does commuting alter household gender dynamics? Do different social groups undertake commuting for different motives? And is commuting but a temporary arrangement before the more longer-term commitment that family emigration suggests? In answering such questions, this paper deepens understanding of a little-studied but growing group of European migrants, and furthers insight into new family geographies emerging in the aftermath of the crisis.
