There are 21 counties in the U.S. state of New Jersey. These counties together have 564 municipalities, or administrative entities composed of clearly defined territory; 253 boroughs, 52 cities, 15 towns, 241 townships, and 3 villages.[1] In New Jersey, a county is a local level of government between the state and municipalities. County government in New Jersey includes a Board of Chosen Freeholders,[2] sheriff, clerk, and surrogate (responsible for uncontested and routine probate),.[3] All of these jobs are elected officials. Counties are responsible for the maintenance of jails, parks, and certain roads.[4] The site of a county's administration and courts is called the county seat.
