In a world where religious affiliation is increasingly fluid, Buddhism has emerged as the only major faith to experience a decline in the last decade. According to the Pew Research Center, this trend is attributed to demographic shifts and the growing number of individuals leaving the religion in adulthood.
The Pew Research Center’s analysis reveals that between 2010 and 2020, the global Buddhist population decreased from approximately 343 million to 324 million, marking a 5% reduction. This occurred despite a 12% increase in the global population, resulting in Buddhists comprising only 4.1% of the world’s populace, down from 4.9%.
Demographic pressures and religious switching are at the heart of this decline, with more people exiting Buddhism than joining it. Although Buddhism attracts some converts, it loses a significant portion of those raised in the tradition compared to other faiths.
The data indicates that for every 100 individuals raised as Buddhists, only 12 convert to the religion, while 22 leave it, opting for another faith or no religious affiliation. This results in a net loss of 10 Buddhists per 100 adherents raised in the faith.
This phenomenon is especially pronounced in East Asia, with surveys suggesting that half of the adults raised as Buddhists in Japan and 60% in South Korea no longer identify with the religion. In contrast, retention is higher in countries like Thailand, which houses the largest Buddhist population globally.
Age demographics also play a significant role. Buddhists tend to be older, with a median age of 40 by 2020, compared to 31 years for the overall global population. Other religious groups have younger median ages, such as Muslims at 24 and Hindus at 29.
Fertility rates among Buddhists contribute to this trend, with an average of 1.6 children per woman, below the replacement level of 2.1. Prolonged low birth rates lead to an ageing population and eventual decline.
Geographically, 98% of Buddhists live in the Asia-Pacific region, with a significant concentration in East Asia, including South Korea, China, Japan, Hong Kong, and Taiwan. These areas already face challenges of ageing populations and low birth rates, contributing to a decrease of 32 million Buddhists from 2010 to 2020.
The Pew Research Center’s findings are part of a broader examination of global religious changes, highlighting the increasing fluidity of religious affiliation and the rise of atheism, agnosticism, and “no religion” identities in various regions.
While Christianity is no longer the majority in some countries, such as the United Kingdom, and ten countries report the largest group as religiously unaffiliated, belief in a higher power persists in many parts of the world. Research by Gallup for the British and Foreign Bible Society and United Bible Societies shows that faith remains significant in daily life for the majority in five out of seven global contexts studied.
Overall, while institutional religious affiliations are weakening in some areas, religion continues to be a significant global force, with Christianity as the largest religious community and Islam as the fastest-growing major faith group. Patterns of belief are increasingly influenced by personal choice, with many individuals reconsidering their inherited religious identities.
