Uniform Crime Reporting (UCR)

The Uniform Crime Reporting program is the FBI's national crime-statistics framework, published through the Crime Data Explorer as offense counts aggregated by year, jurisdiction and offense category down to individual agencies.

Bulk CSV downloads and a free JSON integration keyed via api.data.gov make it the baseline US series for alarm-market sizing.

In this catalog it appears concretely: - FBI Crime Data Explorer (CDE) — "The FBI's official portal for Uniform Crime Reporting data, offering interactive national, state, county, and agency-level crime statistics". - FBI CDE coverage — "national, all states, counties, tribal and university jurisdictions, and individual agencies".

Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.

The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and FBI Crime Data Explorer (CDE) lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open FBI Crime Data Explorer (CDE) and confirm its record — "The FBI's official portal for Uniform Crime Reporting data, offering interactive national, state, county, and agency-level crime statistics" — against the files you actually receive.
2. Open FBI CDE coverage and confirm its record — "national, all states, counties, tribal and university jurisdictions, and individual agencies" — against the files you actually receive.
