If a person is given a death sentence, what is his or her chance of actually being executed? Based on a review of every death sentence in the United States since 1973, the beginning of the modern era of the death penalty, we have found that the most likely outcome isn’t being executed or even remaining on death row as an appeal makes its way through the courts. In fact, the most common circumstance is that the death sentence will be overturned. Here is why that matters.

From 1973 to 2013, 8,466 sentences of death were handed down by U.S. courts, and 1,359 individuals were executed — only 16 percent. Even excluding those who remained on death row as of 2013, only about 24 percent of condemned inmates have been executed. Those sentenced to death are almost three times as likely to see their death sentence overturned on appeal and to be resentenced to a lesser penalty than they are to be executed. Here is a summary of the outcomes:

  • 8,466 death sentences were imposed across the United States from 1973 through 2013.
  • 3,194 were overturned on appeal, composed as follows. For 523, the underlying statute was declared unconstitutional. For 890, the conviction was overturned. For 1,781, the death penalty was overturned, but guilt was sustained.
  • 2,979 remain on death row as of Dec. 31, 2013.
  • 1,359 were executed.
  • 509 died on death row from suicide or natural causes.
  • 392 had their sentence commuted by the governor to life in prison.
  • 33 had some other outcome or a miscellaneous reason for being removed from death row.

Execution is in fact the third most likely outcome following a death sentence. Much more likely is the inmate to have their sentence reversed, or to remain for decades on death row.

This graph shows how these outcomes have changed over time.


Executions have never been the most common outcome of a death sentence. In the early years of the modern death penalty, many were removed from death row because the underlying statute under which they were condemned was ruled unconstitutional. In fact, of 721 individuals sentenced between 1973 and 1976, just 33 were eventually executed. Other reversals have come because inmates’ individual convictions were overturned, and some were exonerated entirely.

But by far the most likely outcome of a U.S. death sentence is that it will eventually be reversed and the inmate will remain in prison with a different form of death sentence: life without the possibility of parole.

Why would reversal of the sentence be the single most common outcome of a death sentence? Capital trials have many unusual characteristics, but a key one is that there is an automatic (or “direct”) appeal through the state appellate courts and, if the death sentence is not overturned by the state appellate or supreme court, a review by a federal judge.

Throwing out a duly enrolled conviction is not something that state or federal appellate courts do because of a misplaced paperclip on a brief. State appellate courts and federal judges are not knee-jerk opponents of capital punishment; they participate in a system that imposes it regularly.

But both Republican and Democratic appointees have voted to overturn these convictions because they so often involve such issues as evidence withheld from the defense, improper instructions to the jury, or other serious flaws in the original trials.

States differ greatly in the degree to which they carry out their legal promise of death, but most operate systems consistent with the trends above: They sentence far more inmates to death than they actually execute. The graph below shows the percent of death sentences that have been carried out, for all 40 states that have had the death penalty as well as for the federal government, which has executed three individuals but has condemned 71.


The average state has a 13 percent likelihood of carrying out a death sentence. Some states—such as Texas, South Dakota, Missouri, and Oklahoma—significantly higher rates, though none of these states reaches a level of 50 percent.

In fact, only one state, Virginia, has executed more than half of the inmates it has condemned. This rate of execution may stem in part from legal shortcomings, however: an American Bar Association report recently found many areas in which Virginia’s “highly efficient” death penalty suffers from deficiencies: in access to post-conviction DNA testing, jury instructions, prosecutors’ provision of evidence to the defense, and other areas.

Several states listed at the top of the graph have not executed a single person, though New Jersey sentenced as many as 52. Pennsylvania and California have very large death penalty systems, but extremely low rates of executing those who have been condemned.

You can see this clearly in the graph below, which shows the number of death sentences imposed and the number of executions carried out for each state.


Texas, Florida, and California have all condemned more than 1,000 individuals to death in the modern period. However, the numbers of executions in these states are 508, 81, and 13, respectively. Virginia has sentenced 152 individuals to die, and 110 have been put to death. The long string of dots along the bottom rows of the graph shows that, in general, no matter how many people the states say they are going to execute, in fact, very few are actually executed.

Regardless of one’s view of the death penalty in principle, these numbers raise questions about how the death penalty is applied in practice. The wide differences across states in the odds of carrying out a death sentence are potentially troubling from an equal protection standpoint. Indeed, David Garland has argued that if it were not for federalism and the strength of the Southern reaction to a series of U.S. Supreme Court decisions in the 1960s and 1970s, we might never have seen the resurgence of the death penalty in the post-Furman world.

Also potentially troubling is the simple fact that most death sentences do not result in executions. In fact, a federal judge recently ruled that California’s death penalty is unconstitutional because it is in fact a penalty of “life in prison with the remote possibility of death.”

Ultimately, the American system of capital punishment arguably creates unnecessary suffering for both those defendants sentenced to death and the surviving family members of the victims of the crimes for which the defendants were convicted. A system that ensures prolonged court time, automatic appeals for the convicted inmate – most of whom are eventually successful – and only a small chance of actual execution is a system built on false promises for everyone, and indeed one that seems to verge on torture.
