"Fostering Youth Transitions 2023: State and National Data to Drive Foster Care Advocacy" is a unique compilation of data designed to inform federal and state policy efforts aimed at making a difference for young people in foster care. This overview brief and detailed profiles of the latest available data from all 50 states, along with the District of Columbia and Puerto Rico, expand on the Annie E. Casey Foundation's first "Fostering Youth Transitions" brief, published in 2018. The expanded data report for 2023 offers state data profiles that trace the experiences of young people ages 14 to 21 who were in foster care between 2006 and 2021. These publications can help advocates, policymakers and practitioners raise national awareness of the unmet needs of young people who experience foster care and spur data-driven systems and policy change to help youth succeed in adulthood.
