Internal affairs investigations per 100 officers, by type and size

AnalysisGroups are never compared as equivalent across type or size band. Correctional agencies, for instance, naturally have different volume patterns than municipal police; each distribution describes only its own peers.

Metric definition. Investigations divided by reported sworn officers, times 100. Agencies with no numeric officer count are listed but not ranked.[1]

Read with care. Groups smaller than 8 agencies are omitted entirely rather than shown as an unreliable distribution, matching the same floor the report-card engine uses.
