Christianity continues to remain strong and vital for the life of Guatemalan society, but its composition has changed over generations of social and political unrest. Roman Catholicism, introduced by the Spanish during the colonial era, remains the largest denomination or church, accounting for 48.4% of the population . Protestants, most of them Evangelical (most Protestants are called ''Evangelicos'' in Latin America) in a wide number of different denominations, made up 33.7% of the population at that time, followed by 1.6% in other religions (such as Judaism, Islam, and Buddhism), and 16.1% claiming no religious affiliation. A more recent 2012 survey reveals Catholics at 47.6%, Protestants at 38.2%, other religions at 2.6%, and the non-religious at 11.6%.
