Half a Century of the U.S. Death Penalty: Data, Disparities, and Uncertain Futures

On the 50th anniversary of the Supreme Court’s 1976 decision *Gregg v. Georgia*, the Marshall Project released an analysis of every death-sentence case filed since the ruling. The study examined more than 9,000 sentences handed down across the United States and found that fewer than one in five of those sentenced to death have been executed. Over a third of the sentences were later overturned, and the average time on death row for those executed in the most recent year was almost 27 years.

In 1972 the Court’s *Furman v. Georgia* decision halted capital punishment, deeming it “morally unacceptable, racially discriminatory and arbitrary.” Four years later, *Gregg v. Georgia* reinstated the death penalty with procedural safeguards intended to reduce arbitrariness, including specific jury instructions and automatic appellate review.

• Sentences: > 9,000 death-sentence convictions (1976-2026).

The Guardian

• Executions: < 20 % of those sentenced have been executed.

The Guardian

• Reversals: > 33 % of sentences were vacated by courts.

The Guardian

• Alternative outcomes: 8 % of cases ended in death by suicide, homicide, or natural causes.

The Guardian

• Current death-row population: > 2,000 inmates; > 25 % have been incarcerated for more than 30 years.

The Guardian

• Racial disparity: Black defendants remain overrepresented on state death rows.

The Guardian

• State actions: 23 states have abolished the death penalty; governors or the president have commuted sentences in > 400 cases.

Proponents argue the penalty deters homicide, yet the low execution rate and long delays undermine that claim. Capital trials routinely exceed one million dollars, and repeated appeals prolong costs. The system also poses a risk of executing innocent individuals, especially as DNA testing and innocence projects have led to exonerations in one out of 50 cases since 1972.

The Guardian

• Governor Mike DeWine (Ohio): Called for abolition, citing failure as a deterrent and emotional harm to victims’ families.

The Guardian

• President Joe Biden: Commuted 37 federal death-row inmates before leaving office, citing concerns about fairness.

The Guardian

• Governor Ron DeSantis (Florida) and Governor Greg Abbott (Texas): Pursued new lethal-injection suppliers and alternative methods such as firing squads.

The Guardian

• Governors Gavin Newsom (California) and Josh Shapiro (Pennsylvania): Halted executions without commuting existing sentences, leaving hundreds of inmates in de facto life sentences.

The Guardian

• Former President Donald Trump: Advocated for a revival of the death penalty and the reintroduction of firing squads.

Critics highlight that Black defendants receive death sentences at a higher rate than white defendants, and that sentencing outcomes vary more by jurisdiction than by crime severity. Legal scholars argue that the procedural “fixes” introduced after *Gregg* have not eliminated arbitrary sentencing or the possibility of wrongful convictions.

The analysis provides percentages for executions, reversals, and alternative deaths but does not disclose the exact number of executions carried out since 1976. Additionally, while racial overrepresentation is noted, precise demographic breakdowns of the current death-row population are absent.

• “Our system is an epic fail,” — Frank Baumgartner, Professor, University of North Carolina at Chapel Hill

The Guardian

• “Every flaw they sought to rectify has been a failure, and now there are new problems that didn’t used to exist.” — Frank Baumgartner

The Guardian

• “It’s such an inefficient system, as you’re wasting huge amounts of money on capital trials that end up in reversals 20 years later,” — Frank Baumgartner

The Guardian

• “They’re not leaving, so they’re just going to go into geriatric care,” — Frank Baumgartner

The Guardian

Debate over the death penalty is intensifying as public support hovers near 50 %. State legislatures in several jurisdictions are considering abolition bills, while federal officials weigh the political ramifications of expanding or restricting execution methods. The forthcoming 2028 election cycle is expected to bring renewed scrutiny of capital punishment policy at both state and national levels.
