According to the 2011 census, 81.3% of the Nepalese population is Hindu, 9.0% are Buddhist, 4.4% are Muslim, 3.0% are Kiratist (indigenous ethnic religion), 1.4% are Christian, 0.1% are Sikhs, 0.1% are Jains and 0.7% follow other religions or no religion. This varies from the 2001 census, where 80.62% percent of Nepalese were Hindu, 10.74% were Buddhist, 4.20% Muslim, 3.60% Kirant (an indigenous religion), 0.45% Christian, and 0.4% were classified as other groups such as Bön. In 1971 Hindus were 89.4% of the population, Buddhists 7.5%, and Kirants statistically 0%. However, statistics on religious groups are complicated by the ubiquity of dual-faith practices, particularly among Hindus and Buddhists.
