Fraser Valley Regional District in the context of "Hope, British Columbia"

The Lower Mainland is a geographic and cultural region of the mainland coast of the Canadian province of British Columbia that generally comprises the regional districts of Metro Vancouver and the Fraser Valley. Home to approximately 3.05 million people as of the 2021 Canadian census, the Lower Mainland contains sixteen of the province's 30 most populous municipalities and approximately 60% of the province's total population.

The region was historically occupied by the Sto:lo, a Halkomelem-speaking people of the Coast Salish linguistic and cultural grouping.

The Metro Vancouver Regional District (MVRD), or simply Metro Vancouver, is a Canadian political subdivision and corporate entity representing the metropolitan area of Greater Vancouver, designated by provincial legislation as one of the 28 regional districts in British Columbia. The organization was known as the Regional District of Fraser–Burrard for nearly one year upon incorporating in 1967, and as the Greater Vancouver Regional District (GVRD) from 1968 to 2017.

Metro Vancouver borders Whatcom County, Washington, to the south, the Fraser Valley Regional District to the east, the Squamish-Lillooet Regional District to the north, and the Nanaimo Regional District and Cowichan Valley Regional District across the Strait of Georgia to the west.

The British Columbia Interior, popularly referred to as the BC Interior or simply the Interior, is a geographic region of the Canadian province of British Columbia. While the exact boundaries are variously defined, the British Columbia Interior is generally defined to include the 14 regional districts that do not have coastline along the Pacific Ocean or Salish Sea, and are not part of the Lower Mainland. Other boundaries may exclude parts of or even entire regional districts, or expand the definition to include the regional districts of Fraser Valley, Squamish–Lillooet, and Kitimat–Stikine.

Home to just under 1 million people, the British Columbia Interior's 14 regional districts contain many cities, towns, airports, and associated regional, provincial, and national parks connected by the province's highway and railway network. The region is known for the complexity of its landforms, the result of millions of years of tectonic plate movements. The ecology of the region is dominated by temperate coniferous forest with patches of alpine tundra found atop its numerous mountain ranges.

Abbotsford is a city in British Columbia next to the Canada–United States border, Greater Vancouver, and the Fraser River. With a census population of 153,569 people (2021), it is the most populous municipality in the province outside metropolitan Vancouver. Abbotsford–Mission has the third-highest proportion of visible minorities among census metropolitan areas in Canada, after the Greater Toronto Area and the Greater Vancouver CMA. It is home to Tradex, the University of the Fraser Valley, and Abbotsford International Airport.

As of the 2021 census, it is the largest municipality of the Fraser Valley Regional District and the fifth-largest municipality of British Columbia. The Abbotsford–Mission metropolitan area of around 195,726 inhabitants as of the 2021 census is the 23rd-largest census metropolitan area in Canada. It has also been named by Statistics Canada as Canada's most generous city in terms of charitable donations for nine consecutive years.

Whatcom County (/ˈwɒtkəm/, /ˈhwɒtkəm/) is a county located in the northwestern corner of the U.S. state of Washington, bordered by the Lower Mainland (the Metro Vancouver and Fraser Valley Regional Districts) of the Canadian province of British Columbia to the north, Okanogan County to the east, Skagit County to the south, San Juan County across Rosario Strait to the southwest, and the Strait of Georgia to the west. Its county seat and largest population center is the coastal city of Bellingham. Whatcom County is coterminous with the Bellingham, WA Metropolitan Statistical Area. As of the 2020 census, the county's population was 226,847.

The county was created from Island County by the Washington Territorial Legislature in March 1854. It originally included the territory of present-day San Juan and Skagit counties, which were later independently organized after additional settlement. Its name derives from the Lummi word Xwotʼqom, also spelled [x̣ʷátqʷəm], perhaps meaning 'noisy' or 'noisy water' and referring to a waterfall. Whatcom County has a diversified economy with a significant agricultural base, including approximately 60% of the nation's annual production of raspberries.

The Central Fraser Valley Regional District was a regional district in the province of British Columbia, Canada, located in the Lower Mainland region, south of the Fraser River and west of Chilliwack.

The regional district was abolished in 1995, with the Township and City of Langley being added to an enlarged Greater Vancouver Regional District and Abbotsford, Matsqui and Sumas, now incorporated together as the City of Abbotsford, added to the new Fraser Valley Regional District, which also includes the eastern half of the former Dewdney-Alouette Regional District and all of the former Regional District of Fraser-Cheam.
