How Many Inmates Die in Jails in America

Uncounted and Unseen: Four Failures That Hide the True Scale of Deaths in U.S. Jails and Prisons

The Data We Don’t Have Related to Jail Deaths

In a modern, data-driven society, it is a reasonable assumption that an event as serious as a death in the custody of the state would be meticulously tracked. We expect that federal and state governments know who is dying in our nation’s jails and prisons, where they are dying, and why. This fundamental data seems like a prerequisite for accountability, oversight, and reform.

The central, surprising truth is that our official data on deaths in custody is dangerously incomplete, inaccurate, and unreliable. This isn’t a minor clerical issue; it is a systemic failure that obscures a national crisis, prevents policymakers from addressing systemic problems, and makes it impossible to hold institutions accountable. A major new report from the National Academies of Sciences, Engineering, and Medicine, titled Strengthening the U.S. Medicolegal Death Investigation System: Lessons from Deaths in Custody, reveals the depth of this failure. This report is not just an academic exercise; it’s a landmark indictment of a foundational failure in America’s public data infrastructure, with life-and-death consequences.

This post shares the most impactful and counter-intuitive takeaways from that report, revealing what we know, what we don’t, and why it matters.

1. The Official Record Itself Is Deeply Flawed

The most basic document for tracking mortality—the death certificate—is itself a surprisingly unreliable source of information. While death certificates are the primary source for cause-of-death data used for everything from legal proceedings to public health policy, studies have found significant errors in them. According to the report, analyses have found errors in death certificates in “approximately 33% to 41% of cases.”

This foundational weakness is compounded by a critical omission. The report points out that there is “no universal requirement that the fact that a death occurred in custody be reported on death certificates.” This means a death caused by neglect in a jail cell could be officially recorded in the national statistics in the same way as a death from a heart attack in a hospital bed, effectively erasing the role of the carceral system from the official record.

This fundamental flaw at the point of origin means any subsequent national data collection effort is already built on a foundation of sand—a problem that the federal government’s own flagship program would dramatically compound.

2. A 20-Year Federal Effort to Count These Deaths Has Failed

In 2000, Congress passed the Death in Custody Reporting Act (DCRA) to create a national system for collecting comprehensive data on these deaths. The goal was to understand who was dying and why. For nearly two decades, the Bureau of Justice Statistics (BJS), a federal statistical agency, successfully managed this data collection, achieving remarkable average annual response rates of 98% from local jails and 100% from state prisons.

However, the responsibility for data collection was later transferred to the Bureau of Justice Assistance (BJA), a grant-making agency. The shift was catastrophic because it moved the task from BJS, an agency designed for rigorous statistical collection and analysis, to BJA, an agency focused on grant administration. This fundamental mismatch of institutional competence all but guaranteed the collapse of the data program.

A 2022 Government Accountability Office (GAO) report on the new system found that it had identified “nearly 1,000 deaths that potentially should have been reported to DOJ but were not.” Furthermore, the GAO found that “70 percent of the records provided by states were missing at least one element required by DCRA,” such as the circumstances of the death.

A separate 2022 report from the Senate Permanent Subcommittee on Investigations delivered a powerful condemnation of this failure:

DOJ’s failure to implement DCRA has deprived Congress and the American public of information about who is dying in custody and why. This information is critical to improve transparency in prisons and jails, identifying trends in custodial deaths that may warrant corrective action—such as failure to provide adequate medical care, mental health services, or safeguard prisoners from violence—and identifying specific facilities with outlying death rates. DOJ’s failure to implement this law and to continue to voluntarily publish this information is a missed opportunity to prevent avoidable deaths.

3. Most People Who Die in Jail Are Legally Innocent

The data we do have from earlier, more reliable collection efforts reveals a shocking truth about who is dying in local jails. The danger for those in local jails is immediate and acute. A striking report finding shows that “Almost 40% of inmates who died in local jails in 2019 had been held for 1 week or less.”

These are not hardened convicts; the vast majority are individuals awaiting their day in court. In 2019, “Almost 77% of the 1,200 persons who died in local jails… were not convicted of a crime at the time of their death.” During that same year, suicide was the leading single cause of death in jails. After adjusting for demographics, inmates were “more than twice as likely as U.S. residents to die by suicide.” These statistics paint a grim picture: a significant number of people, legally innocent and often in crisis, are dying shortly after entering a local jail.

4. Small Jails Have the Highest Death Rates

It might seem intuitive that large, overcrowded jails would be the most dangerous places. However, the data reveals the opposite is true. According to the report’s analysis of Bureau of Justice Statistics data from 2019, inmates “were much more likely to die if they were in a small jail (264 deaths per 100,000 in jails with fewer than 50 residents) than if they were in a large jail (161 deaths per 100,000 in jails with more than 2,500 residents).”

This isn’t a one-year anomaly. The report states that jails with an average daily population of 49 or fewer inmates had the highest mortality rates every single year from 2000 to 2019. This finding directly challenges the media narrative that often focuses on violence and neglect in large, urban ‘superjails,’ revealing a hidden crisis in smaller, often rural, facilities. While the report doesn’t offer a definitive cause, this counter-intuitive finding suggests that smaller facilities may suffer from fewer resources, less access to medical and mental health staff, and inadequate oversight, making them disproportionately deadly for the people held within them.

We Can’t Fix a Problem We Refuse to Measure

The findings from the National Academies are a clear indictment of a broken system. The United States has a critical and systemic failure in its ability to accurately and comprehensively track deaths that occur in the custody of the state. From flawed death certificates to a collapsed federal reporting program, the mechanisms for basic transparency and accountability are failing.

This isn’t just an issue for statisticians and researchers. This lack of reliable data prevents families from getting answers, shields agencies from scrutiny, and fundamentally hinders any effort to improve conditions, provide better medical care, and ultimately save lives. It allows a problem of unknown scale to persist in the shadows. When the most basic data about life and death is deliberately obscured, what hope is there for meaningful oversight and reform?
