FAQ

Q: Why does this page use DCJS data instead of FBI reports?
A: DCJS provides the most complete and consistent record for New York State, reconciling all local agency submissions. FBI data can sometimes undercount when agencies transition systems.

Q: Why present rates instead of raw counts?
A: Rates account for population differences, making it possible to compare areas fairly over time.

Q: How often is this updated?
A: DCJS finalizes each year’s statistics in the fall of the following year. This page is updated periodically when significant new data becomes available.

Q: Are these numbers the same as “reported crime”?
A: Yes – Index Crime statistics reflect offenses reported to police. They may not capture every incident, since not all crimes are reported.
