What characterizes a single parent family?

A single-parent family is characterized by one adult raising their children. This family structure typically arises from various circumstances, including divorce, separation, or the choice to have children without a partner, such as through adoption or assisted reproductive technology.

In a single-parent family, the adult assumes the sole responsibility for child-rearing, which can present unique challenges and dynamics compared to families with two adults. This structure is increasingly recognized and understood in contemporary society, as it reflects the diverse configurations of families today.

The other options depict different family arrangements: two adults raising children together describes a nuclear family, a group of unrelated adults living together refers to a shared household situation that doesn't focus on familial relationships, and extended family living in a single household indicates multiple generations or relatives living together, which is a different structure entirely. Each of these options highlights distinct family dynamics, but they do not align with the definition of a single-parent family.
