County maps

New Jersey, county by county

The same records that fill the county tables, drawn on the state. Pick a measure below. Rates and shares come first because a raw county total mostly tracks how many people live there, which is a fact about New Jersey rather than about policing.

Internal affairs investigations per 1,000 residents, 2025

Counties are grouped by rank into 6 equal-sized groups, compared against the other 20 shown here only. Shading is rate per 1,000 residents, not a grade or a judgment. Boundary values are printed above the ramp.

County outlines are generalized for display and are not legal boundaries. Population is from the 2020 Census. Internal affairs figures are more recent, so a per-resident rate mixes vintages.

Not on this map: the State Police, the Department of Corrections, Transit Police, and other state-level agencies. They operate across county lines and the Attorney General reports them outside the county system, so their activity appears in no county here. They are in the rankings.

County investigations for the latest year divided by 2020 Census population, times 1,000. State agencies operate in every county and are reported outside the county system, so none of their investigations appear in any county.
