Questions about religion data in Bihar
Hindu, at 82.69 per cent of the population as recorded in the Census of India 2011, which is 86,078,686 people.
Muslim, at 16.87 per cent.
Religion is self declared. Enumerators record whatever the respondent states, and answers are not verified against any document. People who decline to answer are counted under not stated.
Each figure is rounded independently, and a small share of respondents do not state a religion. The published totals therefore come very close to 100 without always landing on it.
Not at this level of detail. The 2011 census remains the most recent completed count, and religion tables from it were published in 2015.
