The CIA World Factbook reports that 85% of the population of Puerto Rico identifies as Roman Catholic, while 15% identify as Protestant and Other. Neither a date or a source for that information is provided and may not be recent. A 2013 Pew Research survey found that only about 45% of Puerto Rican adults identified themselves as Catholic, 29% as Protestant and 20% as unaffiliated with a religion. The people surveyed by Pew consisted of Puerto Ricans living in the 50 states and DC and may not be indicative of those living in the Commonwealth.
