Children often—but not always—retain the religious identities, beliefs, and practices of their parents. This project aims to find patterns in what we call “intergenerational religious transmission”, with a particular focus on parents’ religious denominations, their own religious beliefs and behaviours, their intentions to raise their children in their religious traditions, and their children’s religious beliefs, behaviours, and attitudes during childhood. A secondary purpose is to test the “religious residue” hypothesis over time, which contends that religious deidentifiers still maintain aspects (i.e., residue) of their former religious identities.
