According to the 2012 census, 48.4% were Christianity, among whom 26.7% were Protestants (including 11.18% Pentecostal, 11.16% Moravian Church, and 4.4% of various other Protestant denominations) and 21.6% were Roman Catholics. Hindus formed the second-largest religious group in Suriname, comprising 22.3% of the population, the third largest proportion of any country in the Western Hemisphere after Guyana and Trinidad and Tobago, both of which also have large proportions of Indians. Almost all practitioners of Hinduism are found among the Indo-Surinamese population. Muslims constitute 13.9% of the population, which is proportionally the largest in the Americas, and are found mostly among those of Javanese and to a lesser degree those of Indian descent. Other religious groups include Winti (1.8%), an Afro-American religion practiced mostly by those of Maroon ancestry; Javanism (0.8%), a syncretic faith found among some Javanese Surinamese; and various indigenous folk traditions that are often incorporated into one of the larger religions (usually Christianity). In the 2012 census, 7.5% of the population declared they had "no religion", while a further 3.2% left the question unanswered.
