The word is also used to refer to a grouping of dioceses within a member church, commonly known as a metropolitical province, metropolitan province, or internal province. The Church of England is divided into two such provinces: Canterbury and York. The Anglican Church of Australia has five provinces: New South Wales, Queensland, South Australia, Victoria and Western Australia, and an extraprovincial diocese. The Anglican Church of Canada has four: British Columbia and Yukon, Canada, Ontario, and Rupert's Land. The Church of Ireland has two: Armagh and Dublin. The Episcopal Church in the United States of America (ECUSA) numbers, rather than names, its nine provinces. In all cases apart from ECUSA each metropolitan or internal province is headed by a metropolitan bishop with the title archbishop.
