Methodology and source limits
Reporting systems, categories, response programs and willingness to report differ between cities. Counts are reports, not measured rodent populations.
Counts Commonwealth Connect (SeeClickFix) requests in the Rodent Sighting category. The published file has no neighborhood or ZIP code field.
The dataset lists no reuse license, so data downloads are held. Created times are used as published.
The per-capita denominator is the Census city population, not metro-area or county population. The 2025 population estimate is 122,588, from Vintage 2025.
