Faith & Fertility

In the latest issue of Intelligent Life , Anthony Gottlieb offers an interesting commentary on the correlation of faith and fertility in populations today:

Earlier this year a survey by the Pew Forum on Religion and Public Life found that nearly three quarters of American adults professed the religion in which they were raised. But instead of finding this glass to be three quarters full, newspapers preferred to notice that it was one quarter empty. It was the minority of Americans who either switched religions, or abandoned religion altogether, who were highlighted in reports of the survey (” Poll Finds a Fluid Religious Life in U.S. ” ran a headline in the New York Times ). Plainly it does not count as news that religion remains largely a family affair. Yet it should do, because of its largely unnoticed consequences. Some religious groups are dramatically outbreeding others, in ways that have an impact on America, Europe and elsewhere . . . .

If they want to spread their gospel, then, one might half-seriously conclude that atheists and agnostics ought to focus on having more children, to help overcome their demographic disadvantage. Unfortunately for secularists, this may not work even as a joke. Nobody knows exactly why religion and fertility tend to go together. Conventional wisdom says that female education, urbanization, falling infant mortality, and the switch from agriculture to industry and services all tend to cause declines in both religiosity and birth rates. In other words, secularization and smaller families are caused by the same things. Also, many religions enjoin believers to marry early, abjure abortion and sometimes even contraception, all of which leads to larger families. But there may be a quite different factor at work as well. Having a large family might itself sometimes make people more religious, or make them less likely to lose their religion. Perhaps religion and fertility are linked in several ways at the same time.

Mary Eberstadt, a research fellow at the Hoover Institution in Stanford, California, has suggested several ways in which the experience of forming a family might stimulate religious feelings among parents, at least some of the time. She notes that pregnancy and birth, the business of caring for children, and the horror of contemplating their death, can stimulate an intensity of purpose that might make parents more open to religious sentiments. Many common family events, she reasons, might encourage a broadly spiritual turn of mind, from selfless care for a sick relation to sacrifices for the sake of a child’s adulthood that one might never see.
