The CIA World Factbook reports that 85% of the population of Puerto Rico is Catholic, with the remaining 15% divided among Protestantism, Islam, and Judaism. However, the CIA report provides no date or source for the data; it may be outdated. Some sources, including
Pew Research Center, put the Catholic percentage at approximately 70%. However, in a November 2014 report, with the sub-title
Widespread Change in a Historically Catholic Region, Pew Research indicated that only 56% of Puerto Ricans were Catholic and that 33% were Protestant; this survey was completed between October 2013 and February 2014. When discussing Catholicism in Puerto Rico, Archbishop
Roberto Gonzalez Nieves of San Juan offered this comment in 2007. "Its deepest roots are Latino ... U.S. rule began in 1898, at the end of the
Spanish–American War, but
indigenous,
African and Spanish cultures "shaped its identity for 400 years" and that influence "cannot be undone overnight”. The shift from Spanish to U.S. rule brought a wave of anti-Catholic sentiment that led to the prohibition of the processions that are a mainstay of Latin American religious practice, as well as government policies that prohibited schools from teaching in
Spanish. Since the approval of the Puerto Rican Constitution in 1952, popular religious traditions such as processions and festivals honoring communities'
patron saints have taken root again. In April 2025, Governor
Jenniffer González-Colón signs legislation, Law No. 14-2025, "The Fundamental Right to Religious Freedom in Puerto Rico Act," "recognizes the fundamental right to religious freedom of organizations and individuals, and is protected by the United States Constitution, the Constitution of Puerto Rico, and the Universal Declaration of Human Rights. This law can be used in judicial and administrative cases and will allow the party claiming religious freedom to obtain payment of costs and attorneys' fees from the government if it is successful in its case". There is also a Byzantine Catholic community of the St. Spyridon Parish in
Trujillo Alto under the jurisdiction of Archbishop
Roberto González Nieves. ==List of dioceses==
