Share of children living with a single parent

What you should know about this indicator

How is this data described by its producer?

The child lives primarily in a household with only one adult who is reported as a 'parent' of the child. This can be a biological parent or a step- or adoptive-parent. The household may or may not contain other adults – including grandparents and other adult relatives or unrelated adults – but only one adult can be considered as a parent for the household to be classified as a single-parent household.
