The traditional religious emphasis on copious reproduction and common teachings against the use of contraception are having a direct impact on population growth, especially in countries that can't afford it.
Americans are a proactive people. We like to believe that our destinies are wholly within our control, and that everyone gets exactly what she deserves. The "choice" myth is therefore very powerful in all kinds of ways, including in our conversations about women's fertility.
Considering the emphasis religious-right groups put on same-sex marriage, I thought it useful to check birth rates in nations at the time they instituted marriage equality and compare them to today. Has there been a difference in trends already in place?
