Study: Having daughters makes parents more likely to be Republican

In newly published findings that challenge earlier research, Dalton Conley of New York University and Emily Rauscher of the University of Kansas found that having more daughters than sons and having a daughter first “significantly reduces the likelihood of Democratic identification and significantly increases the strength of Republican Party identification.”

Not only is the daughter effect statistically significant, it’s substantively large. They found that overall, “compared to those with no daughters, parents with all daughters are 14% less likely to identify as a Democrat….[and] 11% more likely to identify as a Republican than parents with no daughters,” they write in the journal Sociological Forum.

The daughters effect is considerably stronger among better educated and wealthier parents, they find. But among those farther down the socioeconomic ladder, it weakens to statistical insignificance.
