This research uses FamilyScape 2.0, a microsimulation model of family formation, to estimate the effects of increasing the prevalence and effectiveness of condom use among sexually active men on the incidence of nonmarital pregnancy, abortion and childbearing, as well as on rates of child poverty. These models are informed by analyses of the 2006‐2010 National Survey of Family Growth (to provide a descriptive reproductive portrait of young men and estimates of condom use failure rates) and a review of evidence‐based pregnancy prevention programs that found impacts on condom use.
