Catholicism is the largest religious body in 36 US states
While Protestants collectively outnumber Catholics in the US, researchers of the US Religion Census view various Protestant bodies as their own denominational groups, not collectively. According to this categorization, Catholicism is the largest religious body in 36 US states.
Catholicism has had a significant cultural, social, and political impact on the United States. The religion has historically been associated with left-wing politics and the Democratic Party. Since the 1970s, Catholics have often been regarded as swing voters. The US has the fourth-largest Catholic population in the world, after Brazil, Mexico, and the Philippines.
The Catholic Church has been the single-largest religious body in the US for over a century. The average number of adherents per congregation is 3,000 for Catholics, which is unusually high compared to other groups. No other group has as many as 2,000 adherents per congregation, and only five others have as many as 1,000. Large Catholic congregations are especially common in the West, where there are 4,700 Catholics per congregation.
The Catholic population in the United States has grown by about 2 million people in the past 10 years. Much of that growth has been concentrated in the South — today, the South has more Catholics than any other region. Fifty years ago, 71% of US Catholics were in the Northeast and Midwest; in 2020, 45% were. At the county level, Catholics are most prevalent mainly in New Mexico and Texas along the Rio Grande. There is at least one Catholic congregation in 2,961 US counties, a number bested only by the United Methodists.
The racial and ethnic makeup of the Catholic population varies by region. For example, in the Midwest, 78% of Catholics are White and 15% are Hispanic. In the Northeast, 72% of Catholics are White and 20% are Hispanic. In the South, 44% are White and 45% are Hispanic. And in the West, there are more Hispanic Catholics than White Catholics (58% vs. 34%).

Despite being the largest single religious group, Catholics have the fourth-most congregations of all religious bodies. This is due to the unusually high average number of adherents per congregation, with an average of 3,000 Catholics per congregation, compared to 2,000 for the next closest group. Large Catholic congregations are especially common in the West, with 4,700 Catholics per congregation in this region.
