Country: Sweden Since 2011, the source is register-based household statistics. All persons who are registered at the same housing unit form part of the same household. Information about housing is missing for about 300 000 persons. These people are not included in the household statistics. Earlier data is based on a survey that used a housekeeping unit approach. A household-housing unit may contain several housekeeping units. Reported figures are based on estimated relations between those who occupy the same housing unit. Children are classified based on four different types of relations. Biological parents with children and adoptive parents with children are the two most common types of relations. Children classified by guardianship and ''Other person'' account for a small share. Individuals are classified as children regardless of age if they live with their parents/guardians and don’t have any children or partner in the same household. Single or cohabiting parents, with or without children, who live in a housing unit with other occupants are placed under other households. Information on three-generation households is only available from 2014. The figures refer to households where all persons in the household are part of the same generation chain, but where a person from the middle generation does not need to be present.
