Several Brazilian municipalities have reported significant decreases in crime rates during the first eight months of 2026.

In Serra, robberies in public transport fell by 51.9% compared to the same period in 2025. Local authorities attributed these improvements to increased Municipal Civil Guard presence and data-driven prevention strategies such as ‘Operação Coletivo Seguro’. Similarly, Barra Mansa saw a 77.78% drop in violent lethality and a 75% reduction in intentional homicides.

Taboão da Serra also recorded a 32.9% drop in robberies between January and August 2026 compared to the previous year. Local security officials stated that the data indicates a “sustained downward trend” rather than an isolated occurrence.
