Who covers which part of Union County
Every address in Union County belongs to a municipality (New Jersey has no unincorporated land), and each municipality is covered by its own police department or, in a few rural townships, by the New Jersey State Police. In most New Jersey counties the sheriff’s office mainly serves the courts and the county jail, so local incidents go to the town police. The departments in the table answer only for their own town (Elizabeth Police Department, Linden Police Department, Plainfield Police Department, Rahway Police Department, Westfield Police Department); for any other town, call that town’s police. Union County has about 572,726 residents on 103 square miles of land; about 294,821 of them (51%) live in the 5 towns with their own police departments listed here (Elizabeth 135,829, Plainfield 54,670, Linden 43,950, Westfield 30,559, Rahway 29,813) (U.S. Census Bureau, 2023 population estimate).
