A surge in adult and teenage baptisms in France and the United States signals a modest reversal in Catholic membership trends, even as overall affiliation declines in Western nations.
Paris — Léa Guiragossian, a 22‑year‑old medical student from Bordeaux, attended a papal audience this weekend as one of many recent converts the Vatican hopes will bolster its ranks in Europe and the United States. While the church expands rapidly in Africa and parts of the developing world, it confronts stagnation or decline in Europe, North America and Latin America due to secularism, abuse scandals and competition from evangelical groups.
Data from national bishops’ conferences show rising conversion figures in several Western countries, including France, Germany, Spain, Belgium and the United States. Pope Leo XIV, the first U.S.-born pontiff, addressed new converts in Paris on Saturday, describing their emergence as a “paradox” in a largely secularized region. He urged the church to “respect their personal history” and provide a “welcoming environment,” while acknowledging the challenge of “fostering” these newcomers.
In France, adult baptisms rose to 13,234 in 2026 from 4,263 in 2019, the last full year before the pandemic, according to the French bishops’ conference. Teenage conversions increased to 8,152 in 2026 from 7,404 in 2025. A conference study indicates that new converts are predominantly female and under 40, with the largest cohort aged 18‑25. Clerics note that many converts do not align with politically conservative positions.
Guiragossian, who converted after a two‑year period of study, described her attraction to the “beautiful atmosphere” of candlelit Masses designed for young people. Her parents were Protestant; a Catholic friend’s invitation led her to attend services regularly. She said she values a faith that “loves everyone, accepts everyone and wants everyone accepted.”
Church officials and researchers suggest that many converts are children of less‑religious parents, often from working‑class backgrounds, who encounter the faith through family, friends or social media. They frequently cite personal crises — such as relationship breakdowns, bereavement or a sense of instability in a turbulent world — as catalysts for seeking spiritual grounding. In the United States, comprehensive post‑pandemic conversion statistics have not yet been released, but preliminary data from the Center for Applied Research in the Apostolate (CARA) indicate a rebound in conversion numbers after a pandemic dip. A Catholic app, Hallow, reported a 38 % increase in participants in its initiation program for 2026 compared with 2025, based on responses from 140 of roughly 200 U.S. dioceses.
The U.S. Catholic adult population is growing at a rate roughly equal to overall population growth, driven primarily by immigration and births rather than conversion. Nevertheless, converts remain a small fraction of the global 1.4 billion‑member church. In the Archdiocese of Chicago, 2,430 adults entered the church in 2025, the highest figure since 2013. For Easter 2026, 1,059 individuals prepared for full initiation, up 52 % from 696 the previous year. A survey of the archdiocese found that 12 % of those in the initiation program cited the election of Pope Leo as a factor in their interest, though researchers caution that disentangling the pope’s influence from broader social trends is difficult.
A recent study by the Chicago archdiocese identified Gen Z and millennials as the primary age groups among recent converts, with 34 % of all converts belonging to Gen Z and 35 % to millennials. Researchers note that traditional conversion drivers such as marriage to a Catholic have diminished in importance; instead, many cite the appeal of an “ancient truth system” that offers stability amid rapid societal change. Some converts, like Trinity Hsu, a 29‑year‑old immigration attorney raised Buddhist, reported turning to Catholicism after personal upheaval. Hsu described finding comfort in the communal aspects of Mass and later pursuing a systematic study of the faith, eventually joining a conversion class.
Experts emphasize that while the upward trend is notable, it is insufficient to offset the larger number of individuals leaving the church. Mark Gray, a senior research associate at CARA, warned that attributing the rise to Pope Leo’s papacy alone would be premature, as numerous intertwined factors shape religious affiliation. Tim Weiske, director of parish vitality for the Chicago archdiocese, described the new wave of converts as a “new kind of newcomer” who often approaches the church without familial religious support.
The phenomenon reflects a complex interplay of personal search, cultural context and institutional response, offering a modest but measurable shift within a broader landscape of religious realignment.
