Buddhists () are people who adhere to Buddhism, a religious and philosophical tradition founded by Siddhartha Gautama (the Buddha) in the 5th–4th century BCE in India. Buddhist identity can be religious, cultural, or secular, encompassing monastic practitioners, lay followers, and individuals who adopt meditation and ethical practices without formal rituals.
The term originates from the Sanskrit word Bauddha (बौद्ध), meaning "follower of the Buddha", which itself is derived from Buddha (बुद्ध), meaning "the Awakened One." In ancient India, followers of the Buddha identified themselves as Sakyans (Sakyabhiksu), derived from the name of the Buddha's clan, the Sakyas. The English term Buddhist emerged in the early 19th century, combining Buddha with the suffix "-ist," denoting a follower or adherent. The first recorded use of Buddhist in English was in 1810. In descending order, the percentage of people who identify as Buddhists on each continental landmass stands at: the vast majority (about 98%) in Asia and the Pacific, around 1% in Europe, and less than 1% in Africa, Oceania, and the Americas collectively.
