It consisted of the hundreds (kihlakunta) of Haapajärvi, Kajaani , Saloinen and Oulu and the rural municipality (maalaiskunta) of Oulu in the province of Oulu. The district's borders were redrawn in 1938 to be conterminous with the smaller Oulu Province, absorbing parts of Oulu Province North district. The district was renamed Oulu Province at the same time. The district was renamed Oulu in 1997.

## Electoral system

Oulu currently elects 18 of the 200 members of the Parliament of Finland using the open party-list proportional representation electoral system. Parties may form electoral alliances with each other to pool their votes and increase their chances of winning seats.
