Governance

Each county has a county seat, often a populous or centrally located community, where the county's governmental offices are located. Some of the services provided by the county include: law enforcement, circuit courts, social services, vital records and deed registration, road maintenance, and snow removal. County officials include sheriffs, district attorneys, clerks, treasurers, coroners, surveyors, registers of deeds, and clerks of circuit court; these officers are elected for four-year terms. In most counties, elected coroners have been replaced by appointed medical examiners. State law permits counties to appoint a registered land surveyor in place of electing a surveyor.

Counties in Wisconsin are governed by county boards, headed by a chairperson. Counties with a population of 500,000 or more must also have a county executive. Smaller counties may have either a county executive or a county administrator.<ref>Wisconsin Legislative Reference Bureau. State of Wisconsin 2011–2012 Blue Book Template:Webarchive.
