DNA Exoneration Statistics: 1989 to 2024 in the U.S.

The United States sends more people to jail than any other country in the world.1 As much as twenty percent of the world’s prisoners are in the U.S.2

Unfortunately, two to ten percent of incarcerated Americans are wrongfully convicted for crimes they did not commit.3

DNA exoneration can prove the innocence of people who were wrongly imprisoned even when there is no physical evidence connecting them to the crime.

There have been 3,284 exonerations in the United States as of 2023.4 About 17.5 percent of all exonerations were acquitted of crimes through DNA exoneration.

Facts & Latest Trends in DNA Exoneration

Gary Dotson was the first DNA exoneration case in the U.S. It took place in Alabama in 1989 after serving ten years for a rape that never happened.

Since then, DNA testing has helped prove the innocence of 575 Americans who were unjustly incarcerated for crimes they didn’t commit.4

DNA Exonerees Before and After Prison

Why DNA Exonerees Are Wrongfully Convicted in the U.S.


With about two million people in U.S. jails and prisons, it’s possible that anywhere between 40,000 and 200,000 Americans have been wrongfully convicted.

Based on data collected by the National Registry of Exonerations, the most common causes of wrongful convictions among U.S. DNA exonerees are:4

One or more of these factors led to the wrongful imprisonment of innocent people who would have been acquitted with DNA evidence.

Mistaken Identity

Eyewitness testimony is often used as evidence. While it can be persuasive before a judge and jury, it isn’t necessarily reliable.

Research shows that we cannot recall events exactly as we’ve seen them. So it’s possible that a witness may incorrectly identify a suspect.7

Eyewitness misidentification led to the wrongful conviction of more than half (55.8%) of DNA exoneration cases.4

False Confession or Guilty Plea

False confessions aren’t always prompted by actual guilt or real knowledge of the crime. It can be a person’s response to:7,8

People who are young or have limited education, mental limitations or disorders, or fear of authority figures are also more likely to become false confessors.

About a quarter of DNA exonerees (23.7%) pled guilty to a crime they didn’t commit or made incriminating statements and false confessions.4

Bad Forensic Evidence

Forensic science isn’t perfect. Many techniques still used today haven’t undergone rigorous scientific evaluation and may turn up inaccurate results. 

Some examples of these include:

Even scientifically validated forensic methods like blood typing may provide inaccurate results due to improper handling and testing.

Sometimes, forensic analysts may be involved in misconduct and fabricate results that could lead to a person’s wrongful conviction.

Nearly half of DNA exonerees (45.9%) were unjustly incarcerated with bad forensic evidence.4

False Accusations (Perjury)

When someone is asked to speak in court, they are made to swear to tell the truth. Willfully telling an untruth after taking this oath is an act of perjury.

Using false truths to testify against defendants leads to unfair trials and the conviction of innocent people.

Half of DNA exonerees (52%) were sent to jail or prison by false accusations.4

Official Misconduct

Law enforcers and prosecutors are supposed to uphold truth and justice. But in many cases, they are responsible for wrongfully convicting a person.

Negligence, misconduct, and corruption may cause officials to lose sight of their public duties and secure convictions despite the lack of evidence.

Over half (54.3%) of DNA exonerees were convicted due to official misconduct.4

U.S. States with the Highest DNA Exoneration Rates

DNA Exoneration Statistics: 1989 to 2024 in the U.S. 1
