A dwelling (housing unit) is defined as a room or suite of rooms and its accessories (at least a kitchen or a kitchenette).
Households A household consists of persons who live and work together. For this reason, there can also be multiple households within a dwelling. A household is comprised of persons who live and work together (compare to the explanations for the household list). There can therefore be also multiple households within the same dwelling.
Whether a family constitutes an individual household while residing in the same dwelling as living parents or parents-in-law, you must allow those persons to decide. As a reference to the "joint economies", for example can be the joint receipt of meals, a joint economy income, and the use of the same living spaces are considered. A household can consist also of a single person.
A household is comprised of all persons that live with one another and together keep a common home economy. Therefore, there can also be several households within a housing unit. A household can also consist of a single person. The decision whether a family is formed with those parents or parents-in-law living in the same housing unit, must be left up to these persons. Communal meal times, common housekeeping money or the use of the same living spaces can be seen as an indication of "communal housekeeping." Household personnel and commercial or agricultural employees also belong to the household if they are provided room and board. A household is comprised of all persons that live with one another and keep a common home economy together. (Household personnel also belong to the household if they are provided room and board.) A household can also consist of one person living alone. Other occupants (e.g. subtenants) that manage their own home economy can fill out their own census lists. If a household lives divided across several housing units, all household members are nevertheless recorded in one single census list.
