This report provides an overview of the social and economic characteristics of custodial parents and their children in 2022 using data from the Current Population Survey's Child Support Supplement (CPS-CSS).  According to the 2023 CPS-CSS, about one in four children under the age of 21 lived with only one parent in 2022, while the other parent lived outside the household. Both child support received and the types of both formal and informal child support arrangements in these families are analyzed. Support amounts and types of noncash support provided by the noncustodial parent are also described.
