How rows are built. Agency names, types, counties and ORIs come from the FBI's agency directory. Yearly counts come from the FBI's Offense Type by Agency tables, which list agencies by name only; IROPO links them to ORIs by state, agency type and normalized name. 6 table rows could not be linked and are shown without an ORI.
A dash means the agency did not appear in that year's tables (for example, it had not yet transitioned to NIBRS or did not meet the FBI's publication criteria).
