Final answer:
Approximately 66% of students, if reflective of the U.S. child population, would live with two married parents, a figure that has decreased since 1980. There's also a rise in children living with cohabiting parents and in various other family structures such as single-parent and blended families.
Step-by-step explanation:
If your students are representative of the overall population of U.S. children, based on 2010 census data, you can estimate that approximately 66 percent of them probably live with two married parents. This represents the traditional nuclear family structure, although it has been on a decline from 77 percent since 1980. Additionally, about 3 percent of children live with two cohabiting parents, and the number of children living with unmarried parents has been increasing.
The rise in single-parent families and blended families is significant too. For instance, more than one-quarter of U.S. children live in a single-parent household, and about 16 percent live in blended families. Overall, the diversity of family structures in the U.S. reflects societal shifts and different parenting arrangements.
