Coos Bay is the largest and most economically diverse real-estate market on the Oregon Coast, with a population of nearly 16,000 and a regional role as the medical, retail, education, and professional services hub for the South Coast. The city is part of ‘Oregon’s Bay Area’ — the combined Coos Bay-North Bend-Charleston metro that totals over 30,000 residents.
With approximately 6,895 occupied households (2020 Census) and a median age of 43.5, Coos Bay skews noticeably younger and more working-class than most Oregon coastal cities. Housing stock ranges from mid-century single-family homes across the Empire and Eastside districts to bay-view and bayfront properties, with Charleston (fishing port) offering waterfront character just west of the city. Affordability is a meaningful feature of this market relative to Central and North Coast peers.
