Government and infrastructure
County government
Executive authority is vested in the mayor of Hawaiʻi County, who is elected for a four-year term. Since 2004, the election by the voters has been on a nonpartisan basis. In 2024, Kimo Alameda was elected mayor, defeating Mitch Roth in the general election. Legislative authority is vested in a nine-member County Council. Members of the County Council are elected on a nonpartisan basis to two-year terms from single-member districts. As of December 2016, Hawaiʻi County Council has a female supermajority for the first time, with six women and three men.Administrative districts were originally based on the traditional land divisions called Moku of Ancient Hawaii. Some more heavily populated districts have since been split into North and South districts to make them more comparable on a population basis.
The number following each district is the Tax Map Key number, used to locate state property information. They are assigned in a counter-clockwise order beginning on the eastern side of the island.

County council districts do not directly match the property tax districts because of the variation in the population density of voters in urban areas to rural areas; Hilo & Kailua towns are densely populated areas, while other districts such as Kaū, Puna, Hāmākua, and North & South Kohala are more sparsely populated.
Several government functions are administered at the county level that are at the state or municipal level in other states. For example, the county has its own office of liquor control.
