A 'household' is usually a group of persons who normally live together and take their meals from a common kitchen unless the exigencies of work prevent any of them from doing so. Persons in a household may be related or unrelated or a mix of both. However, if a group of unrelated persons live in a census house but do not take their meals from the common kitchen, then they are not constituent of a common household. Each such person was to be treated as a separate household. The important link in finding out whether it was a household or not was a common kitchen. There may be one member households, two member households or multi-member households.A household with at least one Scheduled Caste member is treated as Scheduled Caste Household. Similarly, a household having at least one Scheduled Tribe member is treated as a Scheduled Tribe household. It includes data on household with ammenities and assets.
