The parish is quite urbanised, hosting the suburbs and exurbs for the town of St Helier. The most notable settlement is located around the Five Oaks area in the centre of the parish and Georgetown in the South. The village of Maufant is located on the boundary with St Martin.

The parish's name derives from Jesus Christ as the Redeemer (Sanctus Salvator). The parish church's full dedication is to St Saviour of the Thorn.

The parish crest displays a thorn with three nails, to represent the Saviour's suffering.

Government House is the official residence of the Lieutenant-Governor, the King's representative in Jersey. It was originally known as Belmont and was acquired in 1821. It was originally constructed in 1814.

The church and parish hall are located half way along the road known as St Saviour's Hill. In the 19th Century the road was opened on its current route. Before then, the road ran through the current grounds of Government House. There was formerly an inn in what is now part of the cemetery of the church.

The parish is a first-level administrative division of the Bailiwick of Jersey, a British Crown dependency. The highest official in the parish is the Connétable of St Saviour. The incumbent office holder is Kevin Lewis, who has held the office since 2022. The parish administration is headquartered at the Parish Hall, next to the parish church.

At present, the parish forms three electoral districts for States Assembly elections and elects five deputies, as well as eight Senators in an islandwide constituency. The current deputies for St Saviour are listed below. Under the proposed electoral reform, St Saviour will form a single constituency, electing five representatives alongside its Connétable.
