How Many People Are Denied Bail?

There is no single national statistic that clearly shows how many people are denied bail, but some studies give insight into how common it is. Many defendants remain in custody before trial because bail is either set too high to afford or they are deemed ineligible for release due to risk. Understanding the available data helps put the scale of denied bail into context.
Data on Pretrial Detention and Bail Affordability
According to the Prison Policy Initiative, more than 400,000 people in the United States are held in jail pretrial on any given day. Many of these detainees either cannot afford bail or were denied release based on risk factors.
The U.S. Commission on Civil Rights found that over 60 % of defendants in local jails are pretrial detainees because they cannot afford the bail amount set.
Estimate of Direct Bail Denial
A bail-bonds website estimated that 15 % to 25 % of defendants are denied bail outright, typically for serious or violent offenses, repeat crimes, or high flight risk.
Yet, that estimate likely covers only a subset of cases, those where bail was explicitly denied, whereas many more remain in custody because they can’t post bail, which is a related but distinct phenomenon.
Key Factors That Influence Bail Denial or Detention
- Risk of flight or danger to the community – Courts may deny bail if the defendant is judged likely to flee or pose a serious threat.
- Seriousness of charges – Violent felonies or offenses involving weapons often lead to bail denial or very high bail.
- Prior criminal history – A significant record can reduce the likelihood of release.
- Inability to afford bail – Even if eligible for release, many remain in custody because they cannot post bail.
Why Numbers Change and Are Difficult to Pin Down
The number of people denied bail varies by state, jurisdiction, and crime type. States have different laws and practices regarding pretrial release. Many statistics combine people who are denied bail with those who simply cannot pay it. Also, local reforms and policies (e.g., risk-based release) affect how many defendants are detained pretrial. Because of these variations, any national figure is approximate.
While exact numbers are hard to obtain, we know that a meaningful portion of the pretrial population does not receive bail or cannot afford it. Estimates suggest perhaps 15 %-25 % of defendants are formally denied bail in some jurisdictions. But when you include those unable to post bail, the number of people detained pretrial without release is substantially higher, over 400,000 daily in the U.S. Many of these detentions are due to bail systems rather than formal denial of bail.
