Whatcom County is a county in the northwest corner of the U.S. state of Washington, along the Canadian border. The administrative center and largest city is Bellingham, which serves as the county seat and primary hub for education, culture and transportation. The county was home to roughly 201,140 people at the 2010 census and has seen steady growth since that count.

Geography and environment

Whatcom County stretches from the shoreline of the Salish Sea to the crest of the Cascade Range. Its landscape includes coastal estuaries and bays, the fertile Nooksack River valley, and high alpine terrain dominated by Mount Baker. The diversity of habitats supports salmon runs, marine life, productive farms and extensive recreation areas, and the county contains several state and local parks as well as portions of national forest.

History and name

The area has long been home to Coast Salish peoples, including the Lummi and Nooksack nations. European and American settlement accelerated in the mid‑19th century. The name "Whatcom" derives from a native word often translated as "noisy water," a reference to local waterfalls and rapids. Over time the county developed ports, timber and agricultural enterprises that shaped its communities.

Economy, education and communities

The county economy blends higher education, maritime commerce, agriculture and tourism. Western Washington University in Bellingham is a major employer and cultural anchor. The Port of Bellingham supports marine industries, while farms in the valley produce berries, dairy and other crops. Cross‑border trade and travel to neighboring British Columbia also influence the local economy.
