New data reveals a profound transformation in religious affiliation across the United States, with retention rates for Protestant and Catholic faiths significantly declining since the 1970s, while those identifying as religiously unaffiliated, often termed "nones," now demonstrate higher retention. The shift, highlighted by researcher Ryan Burge, underscores a decades-long trend reshaping America's religious landscape.
In the 1970s, religious identity was far more stable, with 92% of individuals raised Protestant remaining so as adults. Catholic retention stood at 85% during the same period. Conversely, most people raised without religion would eventually adopt a faith.
Today, these figures have dramatically altered. Protestant retention has fallen to 73%, and Catholic retention has dropped to 66%. Notably, the retention rate for "nones" has surged to 75%, indicating a growing steadfastness among those raised without religious affiliation. According to the tweet from Ryan Burge, > "In the 1970s: 92% of people who were born Protestant, were still Protestants as adults. Catholic retention was 85%. And most people raised without religion picked up faith Now? Protestant retention is 73%. Catholics are down to 66%. The "nones" retention is now 75%."
Pew Research Center data corroborates this trend, noting that a steadily shrinking share of young adults raised Christian have retained their religious identity over the past 30 years. Simultaneously, having no religious affiliation has become "stickier," with a declining percentage of people raised without religion converting to a faith later in life. This dynamic suggests that the religiously unaffiliated population is not only growing through disaffiliation from traditional faiths but also by retaining its own members more effectively.
The rise of the "nones" is largely driven by individuals switching out of their childhood religions rather than being born into non-religious households. Factors contributing to this disaffiliation include the association of Christianity with conservative politics, declining trust in religious institutions, and clergy scandals. While Christianity remains the "stickier" affiliation for older Americans, the unaffiliated identity has become more enduring among younger adults.
This significant demographic shift has profound implications for the future of religious institutions and societal norms in the U.S. Experts continue to analyze the long-term effects of these changing retention patterns on community engagement, political alignment, and cultural values.
