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 Rock Valley 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.

| 2026 | 8 of 12 | 0 | 0 | — |

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.

“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 IA0840400.
