Why there is no county total

These agencies overlap. A sheriff's office, a city police department and a state police post can all work inside UnionCounty, and the FBI gives each its own population. Adding their crimes together would count some residents twice and leave others out, so CrimeTally shows no county rate and ranks nothing. Each agency's page shows its own count, population and rate, from the FBI's September 2026 refresh. An agency whose area crosses a county line is listed under every county it touches.

Informational only, not professional advice. What an agency reported says nothing certain about any one home, street or school.
