Saskatchewan is a prairie and boreal province in west-central Canada, the only province without natural borders. It has an area of 651900km2, nearly 10 percent of which (59366km2) is fresh water, composed mostly of rivers, reservoirs, and the province's 100,000 lakes.Saskatchewan is bordered on the west by Alberta, on the north by the Northwest Territories, on the east by Manitoba, to the northeast by Nunavut, and on the south by the U.S. states of Montana and North Dakota. As of December 2013, Saskatchewan's population was estimated at 1,114,170. Residents primarily live in the southern prairie half of the province, while the northern boreal half is mostly forested and sparsely populated. Of the total population, roughly half live in the province's largest city, Saskatoon, or the provincial capital, Regina. Other notable cities include Prince Albert, Moose Jaw, Yorkton, Swift Current, North Battleford, and the border city Lloydminster (partially within Alberta).
