Note: Models are fixed-effects models analogous to the spline models in Figure 1. Models are estimated separately by whether the marriage was a shotgun marriage, defined as a marriage followed by a first birth within 7 months. We cannot reject the null hypothesis that the trajectories are equal by shotgun marriage. Full results are available in the online supplement, Table A3.
