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.

Crime and clearances

Offences and clearances filed by Cambridge Police Department in its monthly returns to the FBI, added up by calendar year, 2019–2026. Violent crime and property crime are the FBI’s two categories. These are the counts as filed: Police Census does not turn them into a rate.

Violent crime
Year	Months filed	Offences	Cleared	Cleared as % of offences
2026	7 of 12	276	137	49.6%
2025	12	530	269	50.8%
2024	12	526	229	43.5%
2023	12	570	224	39.3%
2022	12	474	165	34.8%
2021	12	372	154	41.4%
2020	12	341	167	49.0%
2019	12	334	139	41.6%

Property crime
Year	Months filed	Offences	Cleared	Cleared as % of offences
2026	7 of 12	1,549	228	14.7%
2025	12	3,163	600	19.0%
2024	12	3,201	354	11.1%
2023	12	2,858	213	7.5%
2022	12	2,636	152	5.8%
2021	12	2,368	150	6.3%
2020	12	2,210	167	7.6%
2019	12	1,991	205	10.3%

Reading the table. “Not reported” means the agency filed nothing for that year; it does not mean zero. A 0 is a figure the agency filed. For 2026 the FBI is still collecting: that year is not complete in the file we read, so where this agency has no 2026 figures the table says “Not yet in the FBI’s file” rather than “Not reported”. We can see that the agency is absent from the file so far; we cannot tell whether it has not filed or has not yet been published, and we do not guess. A year marked “7 of 12” adds up only the months the agency filed, so it is not a full-year total. A dash in the last column means the percentage cannot be worked out: it needs both figures, and at least one offence.

“Cleared” is the FBI file’s clearance count for the year. Clearances in a year can relate to offences from earlier years, so the percentage is not the share of that year’s offences that were solved, and it can exceed 100%. Figures are not adjusted: a year far below the agency’s neighbouring years, or a 0 beside many offences, may reflect what was submitted rather than what happened. The file does not say which, and Police Census does not guess.

Arrests

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

2019	12	1,119

“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.

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 MA0091100.

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 Fatal Encounters (1) and Mapping Police Violence (1). 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.
