Which of these would economists count as a member of a household, but not part of a family?

In economics, a household is defined as a group of individuals living together, regardless of whether they are related by blood or marriage. The concept focuses on the shared living arrangement rather than familial connections.

The choice where a single person with relatives who live elsewhere is considered a member of a household but not part of a family fits this definition perfectly. This individual constitutes a household on their own, as they reside independently, but since their relatives do not live with them, they do not comprise a family unit according to traditional definitions of family, which typically suggest a more direct familial connection or shared residence.

In contrast, those living with siblings or relatives (as in the first and third options) are part of a family unit because they share a living space with people they are related to. The scenario involving the adopted child also doesn't apply since the child, despite being adopted, resides with a family, even if the birth parents live elsewhere. Thus, the correct understanding of households versus families is illustrated well by the situation of the single person living independently.
