This Deep Dive consists of excerpts from The Annie E. Casey Foundation's 2025 KIDS COUNT® Data Book, a comprehensive report analyzing state trends in child well-being across the United States. This annual publication, now in its 36th year, uses federal data to offer a consistent overview of children's status, categorized into four key domains: Economic Well-Being, Education, Health, and Family and Community. The data highlights both progress and setbacks in various indicators, revealing geographic disparities and differences in outcomes based on race and ethnicity. The report aims to equip policymakers, advocates, and communities with the necessary information to make informed decisions that promote the success of children and young adults.
