Estimate for 2026 (scaled from Census 2011 by the state's official RGI projection; not a census count)
Method: the Census 2011 count × Bihar's projected population growth from 2011 to 2026 (+27.1%), from the official projections of the Technical Group on Population Projections (National Commission on Population, MoHFW, with the Registrar General of India), Table 21. The report projects no households, so households use the same ratio. Rounded; a single village can differ widely from its state's average. The next Census will replace these figures.
