New research published in JAMA Network finds no evidence that higher foster care entry rates are associated with lower child maltreatment deaths at the state level. At first glance, this finding appears to land squarely in the middle of a long-running and often polarized debate. Do fewer foster care removals endanger children, or does removing more children keep them safe?
According to this study, neither conclusion is supported by the available data.
Findings like these can both reinforce and challenge assumptions about foster care and child maltreatment fatalities. Some may read it as evidence that reducing foster care entries poses no risk to children, while others may question the strength of the evidence and caution against such an interpretation.
The problem is not that one side is right or the other is wrong, but that the finding itself, given the limits of the data, cannot resolve a debate this complex.
Rather than helping to settle the issue, the study exposes a deeper and more troubling reality: Child welfare policy in the United States is being shaped by incomplete and inconsistent data that were never designed to answer the questions we keep asking.
The authors analyzed more than a decade of state-level administrative data, including 3.4 million records, and found no evidence that increasing foster care removals is associated with reduced child maltreatment mortality, nor that decreasing removals is associated with increased deaths.
Importantly, they do not argue that foster care never saves lives in individual cases. They are explicit that their analysis is population-level and descriptive, not causal.
What the study does show is that foster care entry rates are not predictive of maltreatment mortality at scale. That finding should give policymakers pause. If changing the volume of removals does not move the most serious outcome we care about, then the lever we are debating is likely not the right one.
The limitations of the data matter here. Child maltreatment deaths are rare, low base-rate events, and they are unevenly reported across states. The primary national dataset used to track them, the National Child Abuse and Neglect Data System (NCANDS), is voluntary and not built to generate causal analysis. Fatalities are known to be undercounted, reporting standards vary widely, and cause of death information is often inconsistent or absent. As a result, year-to-year fluctuations frequently reflect reporting practices as much as real change.
None of this is a criticism of the researchers. They are transparent about these constraints and careful in their conclusions. We, too, should be cautious, and in national policy debates, avoid centering findings drawn from data systems with considerable structural limits.
This is how we end up with false binaries: Either remove more children or accept more deaths. Either protect families or protect kids. The research shows these framings fall short and are misaligned with how risk actually develops for families over time.
If foster care entry rates do not predict child maltreatment mortality, that does not mean the system is doing enough. It means we are measuring the wrong things and expecting them to explain outcomes they were never designed to capture at scale.
Child safety is shaped long before a hotline call or a removal decision. It’s influenced by economic stability, access to health care, housing, food, child care and the ability of systems to coordinate effectively. Yet we lack the data that connect these conditions to child welfare outcomes in any meaningful way.
The absence of a clear relationship in this study is not a failure of research. It’s a signal. We cannot continue to rely on incomplete and imprecise data if we are serious about how to prevent harm.
What is needed now is a large-scale federal investment in child safety data and research. That means modernizing national data systems, using consistent definitions across states, and making it possible to link data across child- and family-serving systems. It also means funding long-term research that helps us understand how risk builds over time and what actually prevents the kind of harm that can result in a child’s death. In short, child safety should be treated as a public health challenge focused on learning and improvement, not just compliance.
Families deserve better than policy debates driven by fear, anecdotes or incomplete evidence. They deserve systems that are guided by data that reflect the full reality of their lives and by research that helps us understand what truly keeps children safe.
If we want evidence-based child safety policy, the next step is clear. We must invest in better data and a serious national research agenda that matches the stakes of the problem.
