Religion in South Korea - statistics & facts
South Korea is one of a few countries in the world where both Christmas and Buddha’s birthday are observed as public holidays. It is a multi-religious society, with Christianity, Buddhism, and various other religions coexisting alongside shamanism. Over the past century, Christianity has experienced substantial growth in South Korea, with approximately 20 percent of the population identifying as Christian. Buddhism closely follows, representing around 16 percent of the country's population. The rapid expansion of Christianity in South Korea is particularly noteworthy given the country's deep historical ties to Confucianism. Nevertheless, there has been a noticeable shift in the religious landscape in recent years, especially among the younger generation, who are gradually turning away from religious affiliations.
Meanwhile, shamanism, as the only indigenous religion in the country, has continued to play a significant role in the daily lives of Koreans. A survey conducted in 2023 found that nearly 40 percent of religiously unaffiliated Korean adults and 50 percent of Buddhists had consulted a fortune-teller within the past year. This behavior was also found in a smaller yet significant percentage of Christians, at about 30 percent.
The religious landscape of South Korea
South Korea does not have an official state religion. The Constitution of South Korea explicitly prohibits religious discrimination and guarantees freedom of religion for all citizens, which is largely respected in practice. Christianity is the largest religion in the country, with approximately 15 percent identifying as Protestant and about five percent as Catholic. While Buddhism has a deep-rooted history in South Korea, with its arrival dating back to the fourth century, Christianity was introduced much later in the 18th century. Despite its relatively late introduction, Christianity has gained momentum and prominence, becoming a predominant religion in modern and contemporary Korea. With over 21,000 missionaries serving in 197 countries, South Korea is also known as one of the biggest “exporters” of Christianity worldwide.Meanwhile, shamanism, as the only indigenous religion in the country, has continued to play a significant role in the daily lives of Koreans.
