County government in Nebraska is organized in two ways:
Township counties: the county is divided into townships and governed by a 7-member board of supervisors. 27 counties are governed this way.
Commissioner counties: the county is governed by a 3- or 5-member board of commissioners, but is not divided into organized townships. 66 counties are governed in this way.
Elected county officials
Board of Commissioners (commissioner counties) or Board of Supervisors (township counties)
Other county officials (such as the county Surveyor and the election commissioners) are appointed; in smaller counties, these officials may be shared by multiple counties.
