Irreligion in South Korea: Trends in Secularism and Atheism
While many nations grapple with shifting spiritual landscapes, South Korea presents a unique case of widespread irreligion. Recent data suggests that a significant portion of the population identifies with no religious affiliation, marking a complex relationship between traditional values and modern secularism.
According to the 2015 national census, 56% of South Koreans reported having no religious affiliation. This trend is further highlighted by a 2012 Gallup International poll, which identified South Korea as having the 5th largest population of atheists in the world, with 15% of the population identifying as "convinced atheists de facto."

Historical Context
Before the 20th century, South Korean society was primarily Neo-Confucian. During this era, most citizens were nontheists—individuals who were not concerned with the existence or non-existence of a deity. Following the division of the Korean peninsula in the mid-20th century, the country saw a massive shift; in 1964, approximately 88% of South Koreans reported no religious affiliation.
Although religious participation increased throughout the 20th century, the trend has shifted back toward irreligion in the modern era. The number of "convinced atheists" rose from 11% in 2005 to 15% in 2012.
Statistical Breakdown of Irreligion
To understand the scale of secularism, it is helpful to look at how irreligion varies by age, gender, and time.

Drivers of Secularism
Experts suggest several sociological reasons for the rise in irreligion in South Korea. One primary factor is a growing distrust of hierarchical organizations, which includes many established religious groups. Additionally, the intense pressures of South Korea's demanding education and work systems are cited as reasons why younger citizens may lack the time or inclination to participate in organized religious activities.
