It was located in the southwestern part of the mainland portion of the present-day Alver Municipality in Vestland county.

Alversund covered 59 square kilometres (23 sq mi) upon its dissolution in 1964.

On 15 October 1923, the western district of Alversund (population: 1716) was separated to form the new municipality of Meland.

[3] The municipality (originally the parish) is named after the old Alver farm (Old Norse: Alviðra) since the first Alversund Church was built there.

The mayor was indirectly elected by a vote of the municipal council.
