There are 75 counties in Arkansas, 10 of them with 2 county seats. Each county is governed by a quorum court, consisting of 9–15 justices of the peace, elected for two-year terms; the county judge, who presides, does not vote but has veto power, which may be overridden by a three-fifths vote of the total membership. Elected county officials, who serve two-year terms, include the sheriff, assessor, coroner, treasurer, and county supervisor. In 2002, Arkansas had 499 municipalities, administered under the mayor-council or city-manager form of government. There were 704 special districts and 310 public school districts.
