The 2026 KIDS COUNT Data Book, published by the Annie E. Casey Foundation, indicates a notable decline in children's wellbeing across the United States from 2019 to 2024. The national child wellbeing score dropped from 553 to 547, with 29 states experiencing worsened conditions post-COVID-19. Education and health metrics were particularly affected, as education scores fell from 518 to 417 due to decreased reading and math proficiency in 47 states. Health scores also declined, from 624 to 607, alongside an 8% increase in child and teen deaths. However, some positive trends emerged, with family and community scores increasing from 518 to 608, and economic wellbeing improving slightly from 551 to 557. The report highlighted that 31% of children now live in cost-burdened households, affecting 22.4 million children, marking the first rise in this measure since 2010. Policymakers are urged to continue investing in programs that support children and families to address these challenges.
