About 2,067 people are on death row in the United States as of early 2025, held across 27 states that retain capital punishment plus the federal and military systems. Nearly all were convicted of murder paired with at least one aggravating factor, roughly 98 percent are men, and those executed in 2023 had waited an average of 23 years for the sentence to be carried out.1Bureau of Justice Statistics. Capital Punishment, 2023 – Statistical Tables New death sentences have slowed sharply over the past two decades, but the population already condemned remains large, aging, and concentrated in a handful of states.
What They Were Convicted Of
Every person currently on death row was convicted of murder. In 2008, the Supreme Court held that the Eighth Amendment bars a death sentence for any crime that did not result in, and was not intended to result in, the victim’s death.2Justia. Kennedy v. Louisiana The narrow exceptions are crimes against the state. Treason — waging war against the United States or aiding its enemies — carries a possible death sentence even with no killing proven,3Office of the Law Revision Counsel. 18 USC 2381 – Treason and espionage remains death-eligible under federal law on similar grounds.4Office of the Law Revision Counsel. 18 USC 3591 – Sentence of Death
Not every murder qualifies. Prosecutors must prove at least one aggravating circumstance to seek death. The specific list varies by jurisdiction, but the most common aggravators are:
- Killing more than one person in a single incident or related series.
- Murder committed during another felony such as kidnapping, robbery, sexual assault, or arson.
- Killing a police officer, judge, prosecutor, or other public official in the course of their duties.
- Murder for hire, whether paying or being paid.
- Extreme cruelty, including torture or prolonged suffering.
- Murder of a child, treated as an aggravator in roughly half of death-penalty states.
Federal law adds its own death-eligible offenses on top of ordinary murder. Large-scale drug trafficking operations that involve killing witnesses, jurors, or law enforcement can trigger a federal capital charge.4Office of the Law Revision Counsel. 18 USC 3591 – Sentence of Death Federal capital charges also cover terrorism resulting in death, the murder of a member of Congress or Supreme Court justice, and genocide.5United States Department of Justice. Sentencing – Section: Death Penalty
A capital trial runs in two phases. The jury first decides guilt, then holds a separate hearing on punishment where both sides present aggravating and mitigating evidence.6National Institute of Justice. Law 101 – Special Circumstances (Death Penalty) The jury must be unanimous to impose death. One holdout, and the sentence defaults to life imprisonment in most jurisdictions.
Who the Law Refuses to Execute
Three categorical constitutional protections take the death penalty off the table based on who the defendant is, regardless of what they did. No state can override these.
People Under 18 at the Time of the Crime
No one can be sentenced to death for a crime committed before their eighteenth birthday. The Supreme Court held in 2005 that executing juvenile offenders violates the Eighth Amendment, reasoning that adolescents are less culpable because their brains and characters are still developing.7Justia. Roper v. Simmons The only date that matters is when the crime occurred, not the age at trial or sentencing. Federal law codifies the same restriction.4Office of the Law Revision Counsel. 18 USC 3591 – Sentence of Death
People With Intellectual Disabilities
Executing a person with an intellectual disability is unconstitutional.8Justia. Atkins v. Virginia Courts assess the question through IQ testing, school records, social history, and evaluations of how well the person handles everyday tasks like managing money or navigating social situations. Someone showing significant limitations in both intellectual functioning and daily living skills is permanently ineligible for execution. A lifelong pattern established through childhood records often forms the core of these claims.
People Who Lack a Rational Understanding of Their Execution
A prisoner who does not rationally understand why the state is executing them cannot be put to death. The Supreme Court first established this principle in 1986, holding that the Eighth Amendment prohibits executing someone who is insane.9Legal Information Institute. Ford v. Wainwright In 2007, the Court clarified that bare awareness isn’t enough. A prisoner with severe delusions may know on paper that they are being executed for a murder, but if psychosis prevents them from connecting that fact to reality in any meaningful way, the execution violates the Constitution.10Justia. Panetti v. Quarterman
Unlike intellectual disability, competency shifts. A prisoner with schizophrenia may be lucid on medication and delusional without it. Courts have wrestled with whether the state can forcibly medicate someone solely to make them competent enough to execute, a question that remains unresolved in most jurisdictions. There is no categorical ban on executing people diagnosed with severe mental illness. The protection applies only when the illness destroys the prisoner’s rational understanding at the time of the scheduled execution.
Demographics of Death Row
Death row is overwhelmingly male. About 98 percent of inmates are men, with fewer than 50 women on death row nationwide.11Bureau of Justice Statistics. Capital Punishment, 2019 – Statistical Tables That gap reflects the broader pattern of men committing the vast majority of the aggravated murders that trigger capital charges.
By race, roughly 57 percent of death row inmates are white, about 41 percent are Black, and approximately 16 percent are Hispanic.1Bureau of Justice Statistics. Capital Punishment, 2023 – Statistical Tables The share of Black inmates is about three times their proportion of the U.S. population. That disparity has fueled decades of debate over racial bias in charging decisions, jury selection, and sentencing, particularly because researchers have found that the race of the victim influences whether prosecutors seek death.
Death row is also an aging population. The mean age of current inmates is 54, and people newly sentenced in 2023 averaged 47 years old at sentencing.1Bureau of Justice Statistics. Capital Punishment, 2023 – Statistical Tables Those numbers reflect both how long appeals take and the fact that many capital crimes happen in a defendant’s twenties or thirties, with sentencing sometimes years later. A significant portion of inmates did not finish high school before incarceration.
Geography concentrates death row heavily. Three states alone hold more than half of all death row inmates in the country.1Bureau of Justice Statistics. Capital Punishment, 2023 – Statistical Tables Population size is only part of the explanation. Prosecutorial culture, county-level charging decisions, and local district attorney elections drive much of the variation. Some large states rarely seek death, and a handful of counties in death-penalty states generate a disproportionate share of capital sentences.
How Long They Wait and Why
People executed in 2023 had spent an average of 23 years on death row, the longest average since executions resumed in 1976. More than half of everyone currently on death row has been there for over 18 years. The delays are the product of a deliberate system of mandatory review designed to minimize the chance of executing an innocent person.
After sentencing, the case moves through state appellate courts, which review the conviction and sentence for legal errors. If those appeals fail, the inmate can file for post-conviction relief in state court, raising issues that couldn’t be argued on direct appeal. Ineffective legal representation is the most common claim at this stage. After exhausting state remedies, the inmate can seek federal habeas corpus review, asking a federal court whether the state trial violated the Constitution. Federal habeas petitions can cycle through district courts, circuit courts of appeals, and potentially the Supreme Court. Because a single successful claim often produces a new trial or sentencing hearing rather than release, some cases bounce between state and federal courts multiple times over decades.
Clemency is the last stop. In most states the governor can commute a death sentence to life imprisonment, though procedures vary. Some require a recommendation from a board; a handful give the decision to the board itself. Only the President can grant clemency in federal cases. Despite its availability, clemency in capital cases is rare — more than a dozen death-penalty states have not granted a single act of clemency since 1976.
Wrongful Convictions
At least 202 people sentenced to death in the United States have been exonerated since 1973, their convictions overturned and all related charges dropped. Each one was a jury-convicted capital defendant whom the system later determined was innocent, and that number alone explains much of the caution built into the appeals process.
Perjury and official misconduct are the leading causes. Witnesses have lied, sometimes incentivized by prosecutors offering reduced charges. Official misconduct covers concealing evidence that points away from the defendant, police pressuring witnesses, forensic analysts fabricating results, and prosecutors knowingly presenting false testimony. Other common factors include mistaken eyewitness identifications, coerced confessions, flawed forensic evidence treated as definitive when it shouldn’t have been, and defense attorneys who were underqualified or overwhelmed.
DNA testing has been the most powerful tool for exposing wrongful convictions, but it only applies in cases where biological evidence was preserved. Many exonerations come from the slower work of reinvestigating witness testimony and uncovering prosecutorial files that were never shared with the defense.
Federal, State, and Military Systems
Where a person was convicted determines the facility, the appeals path, the execution protocol, and who holds final authority over whether the sentence proceeds.
State
State convictions account for the overwhelming majority of the death row population. Twenty-seven states currently authorize capital punishment, though several have governor-imposed moratoriums or haven’t carried out an execution in decades. Three states abolished the death penalty in 2020, 2021, and 2023, continuing a national trend of contraction.
Federal
Federal death row is much smaller, usually numbering in the dozens. These inmates were convicted of crimes under federal jurisdiction such as terrorism, murder on federal property, killings tied to large-scale drug enterprises, and offenses like treason and espionage.4Office of the Law Revision Counsel. 18 USC 3591 – Sentence of Death Male federal death row inmates are held at the U.S. Penitentiary in Terre Haute, Indiana, regardless of where their trial took place. Female federal death row inmates are housed at the Federal Medical Center in Fort Worth, Texas.
Military
The military death penalty under the Uniform Code of Military Justice is the smallest category. Only a handful of service members have been sentenced to death by court-martial in the modern era. The President must personally sign an order approving any military execution before it can proceed, and only after the case completes its full cycle of military and civilian appellate review.
How Executions Are Carried Out
Lethal injection is the default method in virtually every death-penalty state. Protocols vary. Some states use a single barbiturate like pentobarbital; others use a three-drug combination that sedates the inmate, paralyzes the muscles, and then stops the heart. Legal challenges and drug-supply shortages have pushed several states to authorize backup methods.
Those alternatives include electrocution, nitrogen hypoxia, the firing squad, and in a few states, lethal gas. Some states let the inmate choose between lethal injection and an alternative; others automatically switch if injection drugs are unavailable. The firing squad has seen a quiet resurgence, with at least one state moving to make it the primary method rather than a fallback starting in 2026.
At the federal level, the Department of Justice in early 2025 reinstated the execution protocol from the first Trump administration, which uses pentobarbital. The same directive ordered the Bureau of Prisons to expand the federal protocol to include the firing squad as an additional authorized method.12United States Department of Justice. Justice Department Takes Actions to Strengthen the Federal Death Penalty The Biden administration had imposed a moratorium on federal executions, which the current administration formally rescinded.
What It Costs
Death penalty cases are far more expensive than cases where prosecutors seek life without parole. The added cost accumulates across every phase. Capital defendants are entitled to two court-appointed attorneys rather than one. Pretrial investigation runs longer and deeper because both sides hire experts in forensics, mental health, and the defendant’s social history. Jury selection takes weeks instead of days because every potential juror must be individually questioned about their willingness to impose death. The trial itself lasts several times longer than a comparable non-capital murder trial because of the separate sentencing phase.
After conviction, decades of mandatory appeals are funded entirely by taxpayers. Incarceration costs are higher too, because death row inmates are held in specialized high-security housing, often in single cells with restricted movement. Studies across multiple states have consistently found that the total cost of pursuing and carrying out a death sentence exceeds the cost of incarcerating someone for life. That gap has become one of the practical arguments cited by states that have moved to abolish capital punishment in recent years.
