Household-dwelling unit

A household-dwelling unit consists of the permanent occupants of a dwelling. Persons who according to the Population Information System of the Population Register Centre are institutionalised, or are homeless, or are abroad, or are registered as unknown, do not constitute household-dwelling units. Additionally, persons living in buildings classified as residential homes do not form household-dwelling units if their living quarters do not meet the definition of a dwelling. In the 1980 census household-dwelling units were also formed of these persons.

The concept of household-dwelling unit was adopted in the 1980 census. In earlier years the concept of household was used. A household consisted of family members and other persons living together who made common provision for food. A subtenant providing for his or her own food constituted a separate household. Since 1980 subtenants have been classified in the same household-dwelling units with other occupants.
