The multifaceted nature of child welfare involvement requires contextually-relevant and rigorous examination across the family, county, and state levels to inform effective policy solutions. This research identifies, evaluates, and contextualizes actionable policy levers for children in foster care with the goals of 1) evaluating the effectiveness of kinship care policies in supporting foster youth; 2) identifying possible gaps in human services for siblings who are raising siblings in foster care; 3) informing actionable policy recommendations across various levels of intervention. This work employs both descriptive and causal quantitative methods in identifying policy opportunities and uses qualitative methods to examine the context necessary for policy interventions serving underrepresented foster youth with kinship caregivers. I use a multi-method approach across three chapters linked by topic that discuss micro-, meso- and macro-determinants of child wellbeing for foster youth. The first chapter uses a quantitative spatial demographic method to explore how spatial geographic contexts can influence the association between child maltreatment reporting rates and drug-related mortality rates at the county level. The second chapter examines the effect of state-level implementation of The Title IV-E Guardian Assistance Payment (GAP) Program from foster care entry to exit. The third chapter highlights siblings raising siblings (SRSs) as one example of kinship care to better understand how they are being served by both formal and informal social support. Together these chapters provide a comprehensive examination of how the social services can target their policy approaches to promote the economic and social well-being of minoritized youth and their kinship caregivers.
