For the past 70 years, Americans have indicated a preference for boy babies over girl babies.
A recent Gallup poll asked Americans which sex they would prefer if they could have only one child. About 40 percent said they would prefer a boy and 28 percent would prefer a girl, with the rest saying they had no preference or opinion on the question.
Gallup has asked some version of this question 10 times since 1941, and the results always indicated a preference for boys.
Men prefer boys more strongly than women do. Conservatives and Republicans are also more likely to say they want boys than Democrats and liberals.
