Rhode Island is the state with the largest Catholic population
Catholicism has a long and complex history in the United States. The religion first came to the country through Spanish and French colonial expansion in the 16th and 17th centuries, with several settlements in California and Texas being named after Catholic saints. The first Catholic church in Rhode Island was established in 1828 in Newport, with the oldest existing Catholic church in the state, St. Mary's, being founded in West Warwick in 1844.
The Diocese of Providence, established in 1872, plays a significant role in serving the spiritual needs of Catholics in Rhode Island. The diocese includes the entire state of Rhode Island and parts of Massachusetts, such as Martha's Vineyard and Nantucket. The Cathedral of SS. Peter and Paul in Providence serves as the mother church of the diocese and is a focal point for the Catholic community.
According to a government report on the census of religious bodies, 76.5 percent of the population of the City of Providence, Rhode Island's capital, are Catholics. The Catholic population in the diocese has experienced significant growth, increasing from 325,000 to 425,000 during the tenure of Bishop Francis Keough. The Catholic Church in Rhode Island also has a strong presence in education, with 30 parishes supporting parochial schools, and various social welfare institutions under Catholic auspices, including hospitals and homes for the aged poor.
While Rhode Island has the largest Catholic population by state, the regional distribution of Catholics in the United States shows that the South has the highest percentage of Catholics, with 32% of the total U.S. Catholic population. This is due to the growing number of Catholics in states like Texas, Louisiana, and Florida. Additionally, as of January 2023, there are 122 Catholics in the United States House of Representatives, representing 28% of the chamber, and 27 Catholics in the United States Senate, representing 27% of the chamber.

Catholics are spread relatively evenly across the US
Catholics are one of the largest religious groups in the United States, with roughly 22% of the population identifying as Catholic. This equates to approximately 77.4 million members as of 2017. The United States has the fourth-largest Catholic population in the world, after Brazil, Mexico, and the Philippines.

Historically, the number of Catholics in the US started to grow rapidly in the 19th century, largely due to immigration from predominantly Catholic countries such as Mexico, France, and Spain.

Hispanic Catholics tend to be younger than White Catholics
As of January 2023, there are 122 Catholics in the United States House of Representatives out of a total of 435 members, including House Majority Leader Steve Scalise. While this is a substantial number, it is worth noting that the number of Catholics in the House has historically been higher. For context, Catholics represented 30.5% of the United States Congress as of January 2019, with 141 Representatives and 22 Senators who were Catholic.
Now, focusing on the comparison between Hispanic and White Catholics:
The decline in Catholic affiliation among Latinos is also evident in the findings that nearly a quarter of U.S. Hispanics are former Catholics. While two-thirds of Hispanic adults (65%) say they were raised Catholic, only 43% currently identify as Catholic. This indicates a significant shift away from Catholicism within the Hispanic community.
It is worth noting that the decline in Catholic affiliation among Latinos is not necessarily due to a rejection of religion altogether. While the percentage of religiously unaffiliated Latinos has grown, there has also been a modest increase in those identifying as Latino evangelical Protestants. This group expresses especially high levels of religious commitment, with nearly three-quarters saying that religion is very important to them.
In summary, the younger age distribution among Hispanic Catholics compared to White Catholics is evident in the demographic data and the declining Catholic affiliation among young Latinos. However, it is important to acknowledge the dynamic nature of religious affiliation and the potential for future shifts in these trends.
