Methodology and source limits

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

Includes resident-filed SW-Rat Rubout requests (Department of Public Works) and HCD-Rodents housing complaints. Excludes SW-Rat Rubout Proactive records, which the city creates itself in very large numbers, plus follow-up and alley-concern records, so these totals are far below the city’s published rat-abatement workload.

Open Baltimore stores created times as local clock time. Records the city marks as deleted are excluded. The Open Baltimore items list no reuse license, so data downloads are held.

The per-capita denominator is the Census city population, not metro-area or county population. The 2025 population estimate is 569,997, from Vintage 2025.

Inspect the source register, transformations and validation notes.
