The rising share of nonmarital births: A response to Ermisch, Martin, and Wu

We are flattered that our recent paper in Demography, GSS (2006), has attracted such close attention from Ermisch Martin and Wu (EMW). In this response we appreciate the opportunity to expand on several key aspects of our paper, but see no reason to substantially revise any of our major conclusions based on EMW comments. Reading EMW, one might think we had proposed the demographic equivalent of Newton’s second law of thermodynamics – the existence of a universal phenomenon, manifest in identical form in all places, for all groups, during all times periods, regardless of circumstances. It will be helpful, then, to review briefly the central points in GSS before turning to the major EMW comments, along with our responses.
