Internal affairs investigations per 100 IA-investigated officers, by type and size

How many investigations an agency opened for every 100 officers named in them. Above 100 means officers are named in more than one investigation on average. Not a rate against department size: the denominator counts officers who were investigated, not officers employed.

Computed by this site

UnitsPer 100: a rate per 100 IA-investigated officers. Each bar counts agencies in a value range; the medians and ranges are computed by this site.

Metric definitionInvestigations divided by the distinct officers named in them, times 100, both as the agency reported them for the year. The officer figure is the AG's unique count by name and badge number within each year and agency, not a staffing count. Agencies with no numeric officer count are listed but not ranked. FBI-reported sworn headcounts, where available, are on the staffing page.^[1]

Each chart has its own scaleA distribution is drawn to its own group and its own value range, so a bar in one group cannot be read against a bar in another. Correctional agencies do not have the volume pattern of municipal police, and neither group is the benchmark for the other.

Groups under 8 are omittedA group with fewer than 8 reporting agencies is dropped rather than drawn, the same floor the report-card engine uses. Every group below states its n.
