We ask a question about the relationship of each person in a household to one central person to create estimates about families, households, and other groups, and to present other data at a household level.

Local, state, tribal, and federal agencies use relationship data to plan and fund government programs that provide funds or services for families, people living or raising children alone, grandparents living with grandchildren, or other households that qualify for additional assistance.
