Nontraditional families and childhood progress through school: a comment on Rosenfeld.

We reexamine Rosenfeld's (2010) study on the association between child outcomes and same-sex family structure. Using the same data set, we replicate and generalize Rosenfeld's findings and show that the implications of his study are different when using either alternative comparison groups or alternative sample restrictions. Compared with traditional married households, we find that children being raised by same-sex couples are 35 % less likely to make normal progress through school; this difference is statistically significant at the 1 % level.
