According to the Pew Forum’s analysis in 2016:
Among those who say they were raised exclusively by Protestants, roughly eight-in-ten now identify with Protestantism, including 80% of those raised by two Protestant parents and 75% of those raised by a single parent who was Protestant. Most who were raised exclusively by Protestants but who no longer identify as such are now religious “nones,” with smaller numbers now identifying with Catholicism or other religions.‘One-in-Five Adults Were Raised in Interfaith Homes’
What does this tell us? Well, it indicates that at least among Protestants the greatest indicator of your potential religiosity is the religion of your parents. Other researchers have confirmed this theory.
In Religious Parenting: Transmitting Faith and Values in Contemporary America, Christian Smith, Bridget Ritz, and Michael Rotolo make this observation on pages 6-7: ‘The best general predictor of what any American is like religiously, after comparing all of the other possible variables and factors, is what their parents were like religiously when they were raising their children…when viewing Americans as a whole, the influence of parents on religiousness trumps every other influence, however much parents and children may assume otherwise.’
This raises an important question: What about the rise of the ‘Nones’, i.e. those with no religious affiliation? Surely, most of their parents weren’t Nones! Andrew Henry’s recent episode of Religion for Breakfast attempts to tackle this related question, ‘Why Do People Leave Their Childhood Religion?’ Since this the first question that arose in my mind when I read that most people follow the religion of their parents, I was excited to see this video being released at this moment.
