What did your mommy and daddy believe?

What did your mommy and daddy believe? June 6, 2010

Young adults in the USA are more likely than ever before to tell pollsters that they don’t see themselves as ‘being’ of any particular religion – they are unaffiliated. The data are clear, but the reason for this shift is not.

It might simply be their age. Maybe they will be more likely to identify with a religion when they’re older. Alternatively, there could be an uptick in the numbers of people who are leaving religion – for good.

Or maybe it’s a snowball effect. More than ever before, American kids are being raised in families that are not affiliated to any religion – you can see that in the graph, which shows how the percentage of kids raised in families with no religion has increased over the years. These kids don’t tend to join a religion, so you can add them to the kids who drop out in each generation.

It’s actually pretty difficult to untangle the statistics to work out what’s going on here. Philip Schwadel, a sociologist at the University of Nebraska, has used a couple of newly developed statistical techniques to try to do just that, using data from the General Social Survey (which has been surveying Americans since the early 1970s).

What he found was that all three effects seem to play a role. He found that, across all generations since around 1990, there has been a sharp increase in the numbers of people reporting that they have no religious affiliation.

But, surprisingly, younger generations aren’t more likely to drop out of religion than they were before. In fact, people born to a religious family in the 60s and 70s are no more likely to switch out of religion than were people born before 1945.

Not so for people born in the period 1945-1960. They are more likely than older generations to switch out of religion. Clearly, growing up in the Hippy generation had its effects!

About one quarter of the increase in non-affiliated young adults can be explained simply by the fact that more and more American kids are being raised in non-affiliated families. This is the snowball effect. When the Hippy generation grew up, they passed on their lack of affiliation to their kids – who were joined by other people who are continuing dropped out of religion at the normal, background rate.

The big question now is what will happen to these young non-affiliated. Based on earlier generations, you might expect a fair number of them to rejoin a religious identity as they age. But will this happen to the Millennial generation? Time will tell!
