“…We surmise these studies found no evidence of differences because they either examined more uniformly advantaged populations, such as planned lesbian families (Bos et al, 2007;Gartrell & Bos, 2010), or used a matched sample design to net out other associated factors (Wainright & Patterson, 2006, 2008Wainright et al, 2004). Nonetheless, previous results and those presented here suggest that any observed disparities in children's outcomes between same-sex couple and different-sex married couple families, although often quite small, are related to the negative effects of socioeconomic hardship (Rosenfeld, 2010) or family instability (Potter, 2012), factors that are disproportionately represented among unmarried families in general (Vespa et al, 2013).…”
