It is difficult to determine which state in the United States is the “most Catholic,” as Catholicism is a global religion with a significant presence in many countries worldwide. However, the state with the highest percentage of Catholics in the United States is Puerto Rico, a territory of the United States. According to the Pew Research Center, approximately 85% of the population of Puerto Rico identifies as Catholic.
In terms of states within the continental United States, the state with the highest percentage of Catholics in New Mexico, where approximately 48% of the population identifies as Catholic. Other states with high percentages of Catholics include Rhode Island, Massachusetts, and New Jersey. It is worth noting that the percentage of Catholics in the United States has been declining in recent years, with the overall percentage of Catholics in the U.S. dropping from around 25% in the 1970s to around 20% today.
