The Fifth Periodical Review of the Boundary Commission for Scotland related the boundaries of new constituencies to those of Scottish local government council areas and to local government wards. Apart from a few minor adjustments, the council area boundaries dated from 1996 and the ward boundaries dated from 1999. Some council areas were grouped to form larger areas and, within these larger areas, some constituencies straddle council area boundaries.
