Methodology and source limits

Reporting systems, categories, response programs and willingness to report differ between cities. Counts are reports, not measured rodent populations.

Rodent Baiting/Rat Complaint includes requests for baiting services. Rows marked duplicate are excluded. Community areas are municipal numeric codes, not named neighborhoods.

The per-capita denominator is the Census city population, not metro-area or county population. The 2025 population estimate is 2,731,585, from Vintage 2025.

Inspect the source register, transformations and validation notes.
