what is the main religion in south korea
Religion in South Korea Religion in South Korea is characterised by the fact that an absolute majority of South Koreans (56.9% as of 2015) have no formal membership in a religious organisation; among those who are members of a religious organisation, there is a dominance of Protestantism, Buddhism, and Roman Catholicism. According to the national census conducted in 2015, 19.7% of the population belongs to Protestantism, 15.5% to Buddhism (Korean Buddhism), and 7.9% to the Roman Catholic Church; in total Christianity is the religion of 27.6% of the Korean population. Buddhism was influential in ancient times and Christianity persuaded large segments of the population already in the 18th and 19th century, yet they grew rapidly in membership only by the mid-20th century, as part of the profound transformations that South Korean society has gone through in the past century,[2] and then have shown some decline from the 2000s onwards. Native shamanic religions (i.e. Sindo) remain popular and could represent a large part of the unaffiliated. Indeed, according to a 2012 survey, only 15% of the population declared to be not religious in the sense of "atheism".[3] According to the 2015 census, the proportion of the unaffiliated is higher among the youth, about 65% among the 20-years old.[4]
