All three territories combined are the most sparsely populated region in Canada, covering in land area. They are often referred to as a single region, The North, for organisational and economic purposes. For much of the Northwest Territories' early history it was divided into several districts for ease of administration. The District of Keewatin was created as a separate territory from 1876 to 1905, after which, as the Keewatin Region, it became an administrative district of the Northwest Territories. In 1999, it was dissolved when it became part of Nunavut.
