Christian churches in sharp decline in South Korea

More than half the population of South Korea describe themselves as non-religious, an interesting statistic for a country that is among the world’s biggest exporters of missionaries.

Christian churches in South Korea are embracing new techniques and technologies to try to attract more adherents.

The reforms are coming into force at a time when South Koreans are moving away from religion. Today, more than half the population say they are non-religious.

The decline of the church is partly because it is seen as archaic and out of touch.
