This brief discusses some of the trends among New York City’s (NYC) children and families that may impact the future of child welfare services in NYC, including transition age youth in foster care. Most trends among NYC’s children and families show marked improvements in living conditions and child well-being over the last several years. In tandem with reforms at the NYC Administration for Children’s Services (ACS), these improvements likely contributed to the long-term declines in foster care entries and census. Some data points, such as the increase in children living in concentrated poverty, raise concerns that more children and families may experience child welfare interventions.
