History

Prior to the 20th century, Korean society was Neo-Confucian, and most Koreans were nontheists, who were not concerned with the question of whether or not God existed. Following the division of Korea in the mid-20th century, approximately 88% of South Koreans said they had no religious affiliation in 1964. While religiousness in South Korea experienced a sharp rise in the 20th century, the majority of South Koreans had no religious affiliation as of 2015 national census. According to a 2012 Gallup International poll, 15% of South Koreans said they were "convinced atheists," an increase from 11% in 2005.
According to some experts, contemporary irreligion in South Korea can be partially attributed to South Koreans' distrust of hierarchical organizations like religious groups. Experts also point to South Korea's demanding education and work systems as reasons why few young South Koreans participate in organized religion.
