Information:  - The Okanagan Country, also known as the Okanagan Valley, is a region located in the Canadian province of British Columbia, and the U.S. state of Washington (where it is spelled the Okanogan Country), defined by the basin of Okanagan Lake and the Okanagan River. With an estimated 400,000 residents, the Okanagan Country spans from the Thompson Plateau near Grindrod, British Columbia in the Okanagan to the Okanagan Highland near Douglas County, Washington in the Okanogan. The largest city in the Canadian portion is Kelowna, with 117,312 residents as of 2011, while the largest city in the American portion is Omak, with 4,881 residents as of 2011. The region took its current name in honor of the Okanagan term, "uknaqín". The mild climate and close proximity to lakes, rivers and mountainous regions make the Okanagan Country an outdoor recreational destination. The region's economy is dominated by the primary industries of agriculture and forestry, although economic diversification has also occurred with retirement communities and recreational tourism. The American portion is considered to be more remote than the Canadian division, with approximately 10 percent of the population.  - Yale - East was a provincial electoral district in the British Columbia legislature that appeared only in the 1894 , 1898 and 1900 elections .

It was a 3-member constituency and retained the name Yale until the 1894 election, at which time it was split into three ridings, Yale-East, Yale-North and Yale-West; other ridings in the southeast of the province had previously been split off, e.g., Fernie, Ymir, Grand Forks, which were later emerged or rearranged into the various Kootenay and Okanagan ridings. In 1903 the name Yale (by itself) was revived, this time as a one-member riding only, the new riding largely based upon Yale-West. Its last appearance on the hustings was 1963. In 1966, it was amalgamated into the new riding of Yale-Lillooet, which was extant until 2009, when most of its core area was made part of the new Fraser-Nicola riding.  - The CanadaUnited States border (French: "Frontière entre le Canada et les États-Unis"), officially known as the International Boundary, is the longest international border in the world between two countries. It is shared between Canada and the United States, the second- and fourth-largest countries by area, respectively. The terrestrial boundary (including portions of maritime boundaries in the Great Lakes, and on the Atlantic, Pacific, and Arctic coasts) is long, of which is Canada's border with Alaska. Eight Canadian provinces and territories (Yukon, British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec, and New Brunswick), and thirteen U.S. states (Alaska, Washington, Idaho, Montana, North Dakota, Minnesota, Michigan, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine) are located along the border.  - Fraser-Nicola is a provincial electoral district in British Columbia, Canada established by the "Electoral Districts Act, 2008".

The upper reaches of the Shuswap basin, southeast of Shuswap Lake and northeast of the Okanagan, are generally considered to be part of Okanagan or of the Monashee Country rather than "the Shuswap". Roughly defined, the Shuswap Country begins on its west at the town of Chase, British Columbia, located on Little Shuswap Lake, west of which is the South Thompson area of the Thompson Country, and includes Adams Lake to the northwest of Shuswap Lake as well as communities in the Eagle River area as far as Craigellachie and/or Three Valley Gap, which is at the summit of Eagle Pass, beyond which eastwards is the Columbia Country.  - Yale-Lillooet was a provincial electoral district for the Legislative Assembly of British Columbia, Canada.  - British Columbia (BC) is the westernmost province of Canada, with a population of more than four million people located between the Pacific Ocean and the Rocky Mountains.

The region is known for its dry, sunny climate, dry landscapes and lakeshore communities and particular lifestyle. The economy is retirement and commercial-recreation based, with outdoor activities such as boating and watersports, snow skiing and hiking. Agriculture has been focused primarily on fruit orchards, with a recent shift in focus to vineyards and wine. The region stretches northwards via the Spallumcheen Valley to connect to Sicamous in the Shuswap Country, and reaches south of the CanadaUnited States border, where it continues as Okanogan County. The Okanagan as a region is sometimes described as including the Boundary, Similkameen and Shuswap regions, though this is because of proximity and historic and commercial ties with those areas.
