Fewer than 5% of people selected for jury duty actually end up seated on a trial jury. That estimate, from the National Center for State Courts, reflects state courts, where roughly 32 million summonses go out each year and about 1.5 million people are placed on a jury. Federal courts seat a larger share of those who report — around 22% — because most disqualifications and no-shows have already dropped out before anyone walks through the courthouse door.1Pew Research Center.

Where the Numbers Come From
In state courts, an estimated 32 million summonses are mailed every year. Only about 8 million recipients actually report to a courthouse, and roughly 1.5 million of those are eventually placed on a trial jury. That works out to under 5% of everyone summoned, and under 1% of all U.S. adults in any given year.1Pew Research Center. Jury Duty Is Rare, but Most Americans See It as Part of Good Citizenship
The federal picture is smaller but similarly steep. In fiscal year 2016, federal courts called roughly 194,000 people for petit jury duty and seated about 44,000 of them. That’s close to 22% of those who showed up, a higher rate than the state figure because the federal pool arriving at the courthouse has already been filtered.1Pew Research Center.

Why So Few Make It onto a Jury
The funnel loses people at every stage. Of those 32 million state summonses, about 4 million come back undeliverable each year. Another 3 million recipients simply don’t show up. Others are disqualified on paper, excused for hardship, or granted deferrals before they ever see a courtroom.
Federal law disqualifies anyone who isn’t a U.S. citizen aged 18 or older, hasn’t lived in the district for at least a year, or can’t read, write, and speak English well enough to follow the proceedings. A mental or physical condition that would prevent effective service, or a pending felony charge or unrestored felony conviction, is also disqualifying.2Office of the Law Revision Counsel. 28 USC 1865 – Qualifications for Jury Service State requirements are similar, with local variations.
The people who do report are called the venire, or jury pool. On a given day a court may have dozens or hundreds of prospective jurors sitting in a waiting room. Most will spend a few hours there and go home without ever entering a courtroom, under the “one day or one trial” model many courts now use.
What Happens Inside the Courtroom
When a trial is ready to begin, a subset of the venire is brought in for questioning. This process, called voir dire, is designed to identify anyone who can’t be fair and impartial for that particular case.3United States Courts. Juror Selection Process The judge handles basic conflict questions. Attorneys then dig into case-specific territory: past accidents in a personal injury trial, attitudes toward corporate defendants in a fraud case, life experiences that mirror the facts.
From that questioning, two tools shrink the pool further.
Challenges for Cause
A challenge for cause asks the judge to remove someone for a specific, articulable reason: actual bias, a relationship with a party, prior knowledge of the case, or an inability to follow the court’s instructions. The judge decides whether the reason holds up. There is no cap on how many for-cause challenges either side can raise.
Peremptory Challenges
Peremptory challenges let attorneys remove jurors without giving a reason, but they’re limited in number. In federal civil cases, each side gets three.4Office of the Law Revision Counsel. 28 USC 1870 – Challenges Federal criminal cases allow more under the Federal Rules of Criminal Procedure — typically ten per side for felonies and three for misdemeanors. States set their own numbers. The one hard limit: peremptory strikes cannot be used to exclude jurors based on race or gender.
How Many Seats Attorneys Are Actually Filling
The number of jurors a court needs is smaller than most people assume, which is part of why the selection rate is so low. Federal civil juries must have between 6 and 12 members, with 6 being the most common in practice.5Office of the Law Revision Counsel. Federal Rules of Civil Procedure Rule 48 – Number of Jurors Federal criminal trials use 12. State courts follow their own rules, with many using 6-person juries for misdemeanors and 12 for felonies. A courtroom holding 60 prospective jurors may only need to seat 6 or 12 of them.
How Courts Build the Pool in the First Place
Federal courts draw names primarily from voter registration lists. Each district’s jury plan must include at least one additional source — commonly driver’s license records — to help the pool reflect a broad cross-section of the community.6Office of the Law Revision Counsel. 28 USC 1863 – Plan for Random Jury Selection From the merged list, courts randomly select citizens and mail them a qualification questionnaire. Those who qualify and aren’t excused get a summons with a report date.3United States Courts. Juror Selection Process
What This Means If You Get Summoned
Statistically, your odds of actually serving on a jury are low. That doesn’t mean you can skip the summons. In federal court, failing to appear can bring a fine of up to $1,000, up to three days in jail, community service, or some combination of those penalties.7Office of the Law Revision Counsel. 28 USC 1866 – Selection and Summoning of Jury Panels Courts usually start with a warning or an order to appear and explain yourself before escalating to real penalties, and state courts follow a similar progression with fines ranging from a few hundred to over a thousand dollars.
If you do serve, the clock resets. After completing federal jury service you generally won’t be called again for at least two years. State courts typically exempt you for one to two years, depending on local rules. Federal and state systems run separately, so service in one does not exempt you from a summons in the other.
