Methodology and source limits
Reporting systems, categories, response programs and willingness to report differ between cities. Counts are reports, not measured rodent populations.
Boston is migrating its 311 system. Inspectional Services was scheduled for transition in fall 2026 in the official guide retrieved September 29, 2026. This release uses only the legacy Rodent Activity category and stops at August 31, 2026.
Boston reported missing legacy 2026 cases on August 12 and said the issue was fixed on August 25. Later revisions remain possible.
The per-capita denominator is the Census city population, not metro-area or county population. The 2025 population estimate is 672,973, from Vintage 2025.
