Officer and civilian counts are full-time employees as filed by the agency in its annual return. A dash means the agency did not report that figure for that year — it does not mean zero.

Arrests

Arrests made by Trenton Police Department, all offences combined, as filed with the FBI and added up by calendar year, 2019–2026.

YearMonths filedArrests

“Not reported” means the agency filed nothing for that year; it does not mean zero. A year marked “7 of 12” adds up only the months filed. For 2026 the FBI is still collecting, so an absent agency reads “Not yet in the FBI’s file”: absent from the file so far, which is not the same claim as having filed nothing.

6 of these incidents record more than one bias motivation. The FBI’s file stores those as a single list; each is shown here as its separate entries joined by “+”, and none is added to a line in the table above.

Absence from this file is not a zero. The file lists incidents that were reported to the FBI. An agency can be missing from it because it recorded none, because it did not report, or because it does not take part in the FBI’s hate crime program, and nothing Police Census holds can tell these apart. In any one year the file lists incidents for only a minority of the agencies the FBI counts as reporting.

The figures are counts of incidents as they appear in the file, as at 14 August 2026; Police Census does not turn them into a rate and does not compare them with other agencies. Offence and bias wording is the FBI’s own, unaltered. Source: FBI Crime Data Explorer, additional datasets, hate crime bulk file, agency record NJ0111100.

What this figure is and is not. It counts deaths recorded as occurring during an encounter with this agency. It is not a finding of wrongdoing, and a death being recorded here says nothing about whether it was lawful. Many involve armed confrontations; some involve none. Police Census publishes counts only and does not name the people who died.

Source: these records come from Mapping Police Violence (9) and Fatal Encounters (8). Where both recorded the same death it is counted once. They are not official statistics, and no federal database records this comprehensively. See Deaths for how the two are combined. Mapping Police Violence data is displayed with attribution to its compiler; the written scope of this site’s right to display it is being confirmed (note dated 11 October 2026).

Why there is no single total here. The FBI publishes two breakdowns of the same assaults — by weapon, and by how the officer was deployed — and nationally they do not agree: the assignment columns sum to 1,869,337 and the weapon columns to 1,744,852, and the two match on only 84% of rows. Police Census publishes the weapon breakdown as the FBI states it rather than picking one basis and calling it ‘the total’. The file’s ‘cleared’ column is not shown either: it sums higher than the assaults themselves, so it is not a subset of what is above and we have not established what it counts.

This comes from the FBI’s Law Enforcement Officers Killed and Assaulted programme. Despite the name, the file carries no officers-killed data at all — those columns are empty for every agency and every year, so this page reports assaults only and says nothing about officers killed.

LEOKA identifies agencies by name, not by the ORI used elsewhere on this site. A row was attached only where exactly one agency in that state reduces to the same base name; 78.7% of rows matched nationwide. An agency with nothing here may have reported no assaults, or may be one of the names that did not match — Police Census does not guess which.

Jurisdictions overlap. These agencies are also recorded against the same county, so a single address may be covered by more than one of them.
