When 2022 survey results show 78% of residents in community policing areas feeling safer, compared with 52% in traditional policing zones, the gap is hard to ignore. Across multiple cities and studies, trust, legitimacy, and even crime outcomes shift enough to change how agencies measure success, not just how they describe it. We compiled the most telling Community Policing Effectiveness statistics across public opinion, implementation fidelity, cost and ROI, and public safety impacts so the patterns can stand up side by side.
Key Takeaways
