Child neglect accounts for most child welfare system involvement in the United States, yet it remains understudied and inadequately prevented. Neglect is closely tied to material hardship, suggesting contributing conditions are often economic rather than willful disregard. This policy brief reports national statistics on neglect, summarizes causal research on prevention, and explores how economic supports and legislative choices shape neglect rates. It shows why current evidence is insufficient and how the field can adopt a more deliberate, measurable agenda to reduce neglect safely.

Why This Matters

National child welfare data consistently show that neglect drives most child welfare system involvement. Understanding how income supports, neglect definitions, and reporting rules shape neglect rates can help policymakers and administrators direct attention toward preventable conditions and reduce unnecessary child welfare involvement while ensuring child safety.

Key Takeaways

• Neglect represents the majority of substantiated child maltreatment cases year after year. 
  Neglect accounts for more than half of all substantiated maltreatment nationally, and its share has increased since the early 2000s. Between 2005 and 2023, the annual number of children with substantiated maltreatment declined substantially, but neglect continued to drive child welfare system totals.
• Income supports are associated with modest but meaningful reductions in child welfare involvement. 
  Across multiple experimental and quasi-experimental studies, income supports, such as refundable tax credits, child support, and public benefits, are linked to reductions in child protective services reports, investigations, and foster care entry, often in the range of 5 to 20 percent. However, because most studies examine “any maltreatment” rather than substantiated neglect alone, we still lack clear evidence about what specifically reduces substantiated neglect.
• State policies and definitions shape measured neglect rates in measurable ways. 
  State choices about how neglect is defined, who is required to report maltreatment, how cases are screened, and what standards of proof apply influence reporting, substantiation, and overall neglect counts. Recent studies show that changes to definitions, reporting rules, intake processes, and administrative practices can shift neglect rates independent of changes in family behavior.
• The current evidence base leaves critical gaps. 
  Few studies focus explicitly on substantiated neglect, despite its prevalence. Variation in state definitions, limitations in data quality, and combined maltreatment outcomes obscure neglect-specific effects. The existing evidence suggests promising policy levers, but stronger, more targeted research is needed to understand what reduces neglect safely and sustainably.

How We Did It

This brief reports national child welfare neglect numbers and trends and reviews rigorous experimental and quasi-experimental research on child maltreatment. It draws primarily on the US Department of Health and Human Services’ Child Maltreatment reports and peer-reviewed studies examining income-support programs and policies and child welfare system outcomes. The analysis also reviews state variation in neglect definitions, mandatory reporting laws, and administrative practices to consider how policy choices influence substantiated neglect rates.
