This category includes any household member not related to the householder by birth, marriage, or adoption. The following categories may be presented in more detailed tabulations:
A roomer or boarder is a person who lives in a room in the household of the householder. Some sort of cash or noncash payment (e.g., chores) is usually made for their living accommodations.
A housemate or roommate is a person aged 15 years and over who is not related to the householder and who shares living quarters primarily in order to share expenses.
An unmarried partner is a person aged 15 years and over who is not related to the householder, who shares living quarters, and who has a close personal relationship with the householder. Responses of same-sex spouse are edited into this category.
Anyone who is not related by birth, marriage, or adoption to the householder and who is not described by the categories given above. Unrelated foster children or unrelated foster adults are included in this category, Other Nonrelatives. A foster child who has been adopted by the householder is classified as an adopted child.
When relationship is not reported for an individual, it is allocated according to the responses for age and sex for that person while maintaining consistency with responses for other individuals in the household. (For more information on allocation, see 2010 Census: Operational Overview and Accuracy of the Data.)
