Cash bail is the practice of releasing a person from pretrial detention only after they deposit a set amount of money as security for returning to court — and people who cannot pay stay in jail despite being legally innocent. The scale is documented: roughly two-thirds of the more than 660,000 people in local jails in 2022 were being held pretrial, per the Bureau of Justice Statistics' 2022 Census of Jails, and pretrial detention has been the fastest-growing slice of the jail population since the 1970s. The rule is money; the consequence is time.

Who sets the amount, and how?
It varies by state, which is the first thing to understand: there is no national bail schedule. In most systems, a judge sets bail at a first appearance within 24 to 48 hours of arrest, guided by a charge-based schedule, a checklist of factors — flight risk, criminal history, community ties — or, in a growing number of jurisdictions, a statistically validated risk-assessment tool. The eighth amendment's excessive-bail clause applies, but the Supreme Court held in United States v. Salerno (1987) that preventive detention without bail is constitutional in some cases, so the constitutional floor is lower than many readers assume.
What happens if you can't pay?
Three documented paths, and a fourth that depends on the county:
- Pay a deposit or the full amount to the court, refundable after appearances in most states.
- Pay a commercial bondsman a non-refundable fee — typically around 10 percent, per state insurance regulations that license bond agents — and the bondsman posts the rest.
- Stay in jail until the case resolves, which research links to plea pressure (more below).
- Where offered: release on recognizance or to a pretrial-services program with check-ins, which large counties run with mixed capacity.
The fee in option two is never returned, including when the person is acquitted or charges are dropped. That asymmetry — a cost of arrest even for the innocent — is a recurring theme in state reform debates.
What does the data show about who stays?
BJS and city-level studies align on the pattern: detained pretrial populations skew toward people charged with lower-level offenses who could not pay modest amounts. A widely cited 2022 study in the Quarterly Journal of Economics by Arpit Gupta, Christopher Hansman, and Ethan Frenchman, using Philadelphia and Miami-Dade court data, found that detention itself increased the probability of a guilty plea and of future crime, and that these effects were concentrated among people denied release on bail amounts they could not pay. Official data adds the demographic frame: Black and Latino people are overrepresented in jail populations relative to arrest rates, per BJS demographic tables. The numbers are attributed; the argument over causes remains contested.
Which states have changed the system?
Four documented reforms with different designs:
| State | Change | Year and status |
|---|---|---|
| New Jersey | Near-elimination of cash bail; risk-based release | 2017; in effect, court reports show jail populations down |
| Illinois | Full abolition of cash bail (Pretrial Fairness Act) | 2023, after the state supreme court upheld it |
| California | Statute ending cash bail passed, then repealed by voter referendum | 2020 referendum kept cash bail |
| New Mexico | Constitutional amendment allowing detention without bail for dangerous defendants | 2016; in effect |
The Illinois case is the largest-scope test: the Illinois Supreme Court upheld the Pretrial Fairness Act in 2023, and the first state reports since implementation show jail admissions down in the participating counties, while prosecutors' associations contest the read on crime trends. Both positions are on the record.
What is the strongest argument for keeping cash bail?
Prosecutors and the commercial-bail industry argue that money release is the only guarantee that reliably produces court appearance, pointing to county appearance-rate statistics and to cases where released defendants were rearrested. The industry's trade association, the American Bail Coalition, has published state-level appearance claims; these are advocacy figures, labeled as such, and they are the documented version of the argument.
What is the strongest argument against?
The evidence-based version, from the academic study above and from New Jersey's own judiciary reports, is that money predicts appearance mainly because it screens for wealth, that detention before conviction pressures guilty pleas from legally innocent people, and that detention's measured costs — lost jobs, housing instability, case outcomes — fall on people not convicted of anything. New Jersey's judiciary reported in 2023 that its pretrial population fell substantially without a measurable drop in court-appearance rates, which is the reform's strongest single data point.
What the record leaves open
State systems are diverging rather than converging: Illinois abolished money bail while other states moved to restrict release. The data that would settle the national argument — matched outcomes across many counties over years — does not yet exist in one place. What the record does establish is who is in jail today, on what legal status, and at what documented cost.
