How is the national electoral register created?
Norway
Representation of the People Act (the Election Act) (Act No. 57 of 28 June 2002)
§ 2-5. Responsibility of the Population Registry Authority
The Population Registry Authority shall in an appropriate manner make available to the electoral authorities information about who shall be included in the register of electors in the municipal authority area.
This has always been the method used for creating the electoral registry.
