This report presents data on single parent families, focusing on the child support income that custodial parents reported receiving during the calendar year prior to the survey as well as other support provided, such as health insurance and non-cash support for children up to age 21 years. Data came from the April 2000 supplement to the Current Population Survey (CPS), which provides information for calendar year 1999. Results indicated that in 2000, custodial parents numbered 13.5 million. Poverty rates declined for custodial parents between 1993-99. More custodial parents worked in 1999, and participation in public programs was lower than in 1993. Demographic characteristics differed between custodial mothers and custodial fathers. About 59 percent of custodial parents had child support agreements in 2000. Custodial mothers were more likely than fathers to have child support awards. About three-quarters of custodial parents received at least some child support payments. Over half of child support awards had provisions for health insurance. Income was higher and poverty was lower for custodial parents receiving all child support due. Total requests for assistance related to child support declined between 1994-00. (SM)
