A Global View on Irreligion

As religion has shaped civilizations and cultures over millennia, the dialogue around religious beliefs evolves as well. An increasingly complex conversation surrounds the growth of people who identify as 'religiously unaffiliated,' which encompasses those who identify as atheists, agnostics, and those who simply do not align with any specific dogma.

  • The leading atheist country, Czech Republic (78.4%) is notable due to the typically dominant influence of Catholicism in the country.
  • Estonia and Japan, with 60.2% and 60% respectively, stand out as countries with significant atheist populations compared to their respective regions. Estonia diverges from a predominantly Christian Europe, while Japan significantly contrasts to a largely religiously-inclined Asia.
  • Among top countries with a significant atheist population, there is a substantial representation from East Asia, including North Korea, Japan, Hong Kong, and China, conveying a regional pattern towards irreligion or atheism.
  • In the United States, often considered a religious country with diverse faith affiliations, the data shows a notable 18.6% of the population identify as atheists, ranking it as the 30th most atheist-populated country.
