Between 2003 and 2013, New York recorded 4.4 million stop and frisk stops, yet the NYPD’s own frisk yield analysis found a hit rate of only about 10 percent, so most frisks did not produce contraband. The same legal disputes that led to constitutional scrutiny also show up in public health and trust measures, including a 14 percent higher odds of depressive symptoms among youth exposed to stop and frisk and measurable drops in cooperation.
Key Takeaways
- 4.4 million stops occurred between 2003 and 2013, meaning stop-and-frisk was used on a multi-million scale over roughly a decade.
- Stop-and-frisk was suspended by NYPD in 2020 as part of policy changes following court and settlement reforms, meaning the core practice was effectively curtailed.
- In the NYPD’s own Frisk Yield analysis, the ‘hit rate’ for frisks was about 10% (contraband found), meaning only about 1 in 10 frisks produced a hit on average.
- In Floyd v. City of New York, the court found that the NYPD frequently lacked reasonable suspicion to justify stops, meaning many stops were not supported by the legal standard.
- The federal court held that officers’ stops were often not supported by reasonable suspicion, meaning constitutional thresholds were frequently unmet.
- A 2018 JAMA Internal Medicine study reported that exposure to stop-and-frisk was associated with increased likelihood of depressive symptoms among youth, meaning policing practices had measurable mental health harms.
- A 2019 study published in the Proceedings of the National Academy of Sciences found stop-and-frisk policies affected public health and well-being, meaning enforcement practices had broader societal impacts than arrest statistics alone.
- A 2017 RAND report found that legal and community legitimacy are critical to policing effectiveness, suggesting stop-and-frisk’s disproportionate burden can undermine legitimacy, meaning perceived fairness can affect cooperation.
- A 2017 study in Social Science & Medicine reported that police-stop exposure is associated with adverse mental health outcomes, implying potential downstream healthcare costs, though not directly quantified as dollars in that paper.
- A 2019 report by the Office of the New York State Comptroller indicated that legal compliance and oversight for consent decrees can require continuing administrative spending, meaning public-sector compliance carries ongoing costs.
- $2.6 million: annual training and compliance staffing costs for officers and supervisors under documented policing reform implementation plans.
- Alabama statute: “Reasonable suspicion” standard remains the constitutional baseline for stop-and-frisk-type investigatory detentions under the Fourth Amendment and relevant state codifications (quantified in case law applications).
- 27% of youth in a cohort reported at least one stop exposure (self-reported) over a multi-year period, linking exposure prevalence to youth policing experiences.
- 14% higher odds of depressive symptoms among youth exposed to stop-and-frisk in a longitudinal analysis (adjusted odds ratio reported in the study).
- 4.0% decrease in self-reported trust in police after stop exposure in a panel study of policing experiences, reported as a marginal difference in trust scores.
From 2003 to 2013, millions of stops yielded only about a 10 percent contraband hit rate.
Stop Volumes
14.4 million stops occurred between 2003 and 2013, meaning stop-and-frisk was used on a multi-million scale over roughly a decade.[1]
Single source
2Stop-and-frisk was suspended by NYPD in 2020 as part of policy changes following court and settlement reforms, meaning the core practice was effectively curtailed.[2]
Verified
Stop Volumes Interpretation
Across the stop volumes category, stop-and-frisk reached a multi million scale with 4.4 million stops between 2003 and 2013, and then its use was effectively curtailed when the NYPD suspended it in 2020.
Search Outcomes
1In the NYPD’s own Frisk Yield analysis, the ‘hit rate’ for frisks was about 10% (contraband found), meaning only about 1 in 10 frisks produced a hit on average.[3]
Directional
Search Outcomes Interpretation
For Search Outcomes, the NYPD’s own Frisk Yield analysis shows only about a 10% hit rate, meaning just 1 in 10 frisks typically turned up contraband.
Legal Findings
1In Floyd v. City of New York, the court found that the NYPD frequently lacked reasonable suspicion to justify stops, meaning many stops were not supported by the legal standard.[4]
Verified
2The federal court held that officers’ stops were often not supported by reasonable suspicion, meaning constitutional thresholds were frequently unmet.[5]
Verified
Legal Findings Interpretation
Under the Legal Findings angle, Floyd v. City of New York and a federal court both pointed to a recurring pattern in which officers frequently lacked reasonable suspicion, showing that many stops fell short of the constitutional standard.
Performance & Effectiveness
1A 2018 JAMA Internal Medicine study reported that exposure to stop-and-frisk was associated with increased likelihood of depressive symptoms among youth, meaning policing practices had measurable mental health harms.[6]
Verified
2A 2019 study published in the Proceedings of the National Academy of Sciences found stop-and-frisk policies affected public health and well-being, meaning enforcement practices had broader societal impacts than arrest statistics alone.[7]
Verified
3A 2017 RAND report found that legal and community legitimacy are critical to policing effectiveness, suggesting stop-and-frisk’s disproportionate burden can undermine legitimacy, meaning perceived fairness can affect cooperation.[8]
Verified
4A 2022 peer-reviewed study in PLOS ONE found that increased stop exposure among youth correlated with adverse outcomes including reduced trust, meaning community legitimacy effects may be measurable.[9]
Verified
Performance & Effectiveness Interpretation
Across studies, increased stop-and-frisk exposure is linked to measurable harms like higher depressive symptoms among youth in a 2018 JAMA Internal Medicine study and worse trust outcomes in a 2022 PLOS ONE study, indicating that the practice undermines performance and effectiveness by damaging public health and community legitimacy rather than improving results.
Cost Analysis
1A 2017 study in Social Science & Medicine reported that police-stop exposure is associated with adverse mental health outcomes, implying potential downstream healthcare costs, though not directly quantified as dollars in that paper.[10]
Verified
2A 2019 report by the Office of the New York State Comptroller indicated that legal compliance and oversight for consent decrees can require continuing administrative spending, meaning public-sector compliance carries ongoing costs.[11]

3$2.6 million: annual training and compliance staffing costs for officers and supervisors under documented policing reform implementation plans.[12]
Directional
41.9% of operating budget increase tied to compliance and reform in a municipal finance analysis of public safety oversight.[13]
Directional
Cost Analysis Interpretation
Cost analysis suggests that implementing and maintaining stop and frisk related reforms is not a one time expense, with annual training and compliance staffing totaling $2.6 million and compliance and reform accounting for 1.9% of public safety budget increases, while studies also point to downstream mental health impacts that could further strain healthcare resources.
Legal Standards
1Alabama statute: “Reasonable suspicion” standard remains the constitutional baseline for stop-and-frisk-type investigatory detentions under the Fourth Amendment and relevant state codifications (quantified in case law applications).[14]
Verified
Legal Standards Interpretation
Across the legal standards for stop and frisk in Alabama, courts continue to treat the reasonable suspicion standard as the constitutional baseline, showing that Fourth Amendment and state codification requirements remain tightly aligned in how these detentions are evaluated.
Public Health & Social Impact
127% of youth in a cohort reported at least one stop exposure (self-reported) over a multi-year period, linking exposure prevalence to youth policing experiences.[15]
Verified
214% higher odds of depressive symptoms among youth exposed to stop-and-frisk in a longitudinal analysis (adjusted odds ratio reported in the study).[16]

Verified
9Stop-and-frisk policing was linked to an estimated 33% increase in civilian complaints compared with counterfactual policing in a city-level econometric study of complaint rates.[23]
Verified
Public Health & Social Impact Interpretation
Across public health and social impact outcomes, stop-and-frisk exposure is linked to meaningful harm, including a 14% higher odds of depressive symptoms and a 33% increase in civilian complaints, alongside disruptions like reduced school attendance and lower trust in police.
Performance Metrics
137% of agencies reported using stop data dashboards for internal review of stop outcomes in a 2022 policing analytics survey (analytics adoption metric).[24]
Verified
Performance Metrics Interpretation
In the Performance Metrics category, the fact that 37% of agencies used stop data dashboards for internal review in 2022 suggests analytics-driven tracking of stop outcomes is still limited.
Industry Trends
144% of agencies reported increasing reliance on body-worn cameras for stops as a reform measure between 2019–2021 (technology adoption metric).[25]
Single source
218% reduction in complaints after implementation of procedural justice training in a multi-site evaluation (complaint rate change metric).[26]
Verified
Industry Trends Interpretation
