Roman Catholicism is an integral part of Chile's history and culture, and the great majority of Chileans consider themselves Roman Catholic. However, their numbers have been declining since 1970, while the Protestant population has been increasing. The 1970 census showed that about 90 percent of the population was nominally Roman Catholic, and a little over 6 percent was Protestant. The 1982 census did not include questions on religion. The 1992 census showed that 76.9 percent of the population fourteen years of age and older declared itself Catholic, while 13.1 percent declared itself either "Evangelical" or "Protestant". This latter percentage reflected a moderate but steady increase with each census since 1920, when only 1.4 percent of the population was counted as Protestant. About 90 percent of Protestants belong to Pentecostal (Evangelical) denominations.
