| Households |
The entire group of people related or not by kinship, who live in the same house and share household expenses. If there are dependencies in a house or rooms occupied by domestic servants with their families or rented to another family, these groups should be considered as separate households. |
| Collective dwellings |
An establishment where people live, temporarily or permanently, not as families or households but where they do share meals and are subject to an interest or common scheme. For the purposes of the census, hotels, homes, schools, asylums, barracks, hospitals, pensions, prisons, and other similar establishments fall into this category. If there are family habitations within the collective dwelling for administrative or service purposes, they must be considered as independent households. |
