Vice President JD Vance's Memoir and Pew Study Examine Catholic Conversion Trends

Vice President JD Vance's memoir about his conversion to Catholicism, released on Tuesday, highlights a distinct group within the U.S. Church. Vance stated in March that his story of regaining faith occurred because he had initially lost it, prompting questions about why he had "strayed from the path."

A new analysis by the Pew Research Center reveals that 1.5% of U.S. adults are converts to Catholicism, constituting about 8% of all Catholics. Despite these conversions, the Church loses eight former Catholics for every adult it gains, challenging notions of a widespread Catholic revival.

Converts tend to be demographically specific, often identified as whiter, more conservative, and more observant than "cradle Catholics," or those born into the faith. Most converts originate from other Christian backgrounds, with 59% raised Protestant, 9% in another Christian tradition, and 22% having no childhood religious affiliation. The primary driver for conversion is family, with 49% citing a Catholic spouse, partner, or a desire to marry in the Church, while other reasons like belief in church teachings or spiritual fulfillment are less common.

Catholic converts demonstrate higher levels of observance in some areas. Approximately 38% attend Mass weekly, compared to 28% of cradle Catholics, and 58% receive Communion every time they attend Mass, versus 34% of cradle Catholics. However, Pew found no statistically significant difference in rates of prayer or confession between the two groups.

Vance aligns with several aspects of the convert profile, being white, U.S.-born, Republican, and raised in a loosely evangelical family. However, his conversion story diverges from the most common pattern, as his wife, First Lady Usha Vance, is Hindu, whereas nearly half of converts cite a Catholic spouse or church marriage as a reason.

David Campbell, a political science professor at the University of Notre Dame, characterized the trend as "religious resilience" rather than a "religious revival." He noted that while some parishes are seeing an increase in new converts, it is premature to determine its long-term impact on church membership or its political composition. Campbell also suggested that new converts often perceive their Catholicism as a political identity, while cradle Catholics may view it as part of their ethnic upbringing.

U.S. Catholicism is also significantly shaped by Hispanic and immigrant Catholics. Pope Leo XIV's stance on migrant rights has been positioned against certain Trump-era political views among American Catholics. Vance's use of "ordo amoris," or "order of love," to advocate for prioritizing citizens, drew criticism from senior Catholic figures, including Pope Francis before his death.

Vance shares many demographic and political characteristics with America's Catholic converts. However, the Pew data indicates that converts are not currently driving a broad resurgence for the Catholic Church in the U.S.

Pew's findings are primarily based on its 2023-24 Religious Landscape Study, conducted from July 17, 2023, to March 4, 2024, involving 36,908 U.S. adults. The analysis also incorporated a February 2025 survey of 9,544 U.S. adults and a May 2025 survey of 8,937 U.S. adults, with estimates for Catholic converts based on smaller subsamples carrying larger margins of error.

According to Axios, Vance's memoir aims to shed light on this specific group within the U.S. Catholic Church. (Source: Axios)
