ABOUT ISLAND COUNTY:

Island County, Washington has a land area of approximately 208 square miles, about 309 square miles of water, 8 zip codes, and is one of the most densely populated of the 39 counties in the state.  

Although it is the next to the smallest county in the state, Island County is ranked 14th in overall population of the 39 counties, accounting for its high population density.

Island County officially consists of nine islands located in the Puget Sound.   Three of the islands, Whidbey, Camano, and Ben Ure, are inhabited.  All three of its incorporated cities, Oak Harbor, Coupeville, and Langley, are located on Whidbey Island.

Roughly 60 % of the county is water and includes all or portions of the Straits of Juan de Fuca, Admiralty Inlet, Mutiny Bay, Useless Bay, Cultus Bay, Dugualla Bay, Skagit Bay, Saratoga Passage, and Port Susan.

 

INHABITED ISLANDS:

WHIDBEY ISLAND is the largest island in Island County, covering approximately 168.67 square miles.  It is the largest and longest island in Washington and on the Pacific coast of the lower 48 states.

CAMANO ISLAND is the second largest island in Island County, covering approximately 39.77 square miles.  Is is part of the Stanwood Camano School District and has two schools on the Island.

BEN URE ISLAND is the third inhabited island in the county and is divided into seventeen lots.  It is inhabited only part of the time and is accessible only by boat.  The Washington State Parks and Recreation Department has been acquiring the lots, and much of the Island is now part of Deception Pass State Park, including a cabin that can be rented by the public.

 

UNINHABITED ISLANDS:

The remaining islands in Island County include: Baby, Deception, Kalamut, Smith, Minor, and Strawberry Islands.

Smith Island has a navigational light and a weather station operated by NOAA (National Oceanographic and Atmospheric Administration).  Another Smith Island in Washington lies at the mouth of the Snohomish River and is part of the river's delta.

Minor Island is next to and sometimes attached to Smith Island.  It too has a navigational light.

Stawberry Island is one of two in the state of Washington.  Skagit County also has a Strawberry Island, located just west of Cypress Island. 

Deception Island is located northwest of Whidbey Island and is owned by Washingtopn State.

Kalamut Island, located near Oak Harbor, does not appear on any aerial or satellite photos of the area, and may no longer exist.

During some low tides, both Baby Island and Minor Island connect to Whidbey and Smith Islands, respectively.  It is then possible to walk to them.  During some high tides, they may be completely covered by water.

 

POPULATION GROWTH:

Island County is the 5th most densely populated county in Washington state.  It ranks 14th of the thirty-nine counties in overall population, but is next to the smallest in land mass.

Although the overall growth rate in Island County has about average for the state, the population of people 65 and older increased by 41% since the year 2000.  That was the 6th highest increase among the thirty-nine counties in the state.

The increase in the number of residential housing units in Island County since the year 2000 exceeded the state average by about 36%.  Kittitas, Whatcom, Mason and Island Counties experienced around 19% average growth in residential housing units since the year 2000.  Only Franklin, Clark, and Thurston Counties had higher percentage growth in housing units during that time period.
