Regional context

Snohomish County is situated between northern Puget Sound to the west and the crest line of the North Cascade Range to the east. It shares its northern border with rural Skagit County and borders King County to the south. Snohomish County is separated from Camano Island (part of Island County) by Davis Slough. The highest point in Snohomish County is Granite Peak (10,541 feet).

Due to its proximity to and shared labor market with King County, Snohomish County is incorporated into the Seattle - Bellevue - Everett Metropolitan Division and the Seattle - Tacoma - Bellevue Metropolitan Statistical Area, as designated by the Office of Management and Budget (OMB) and used by the Bureau of Labor Statistics, the U.S. Census Bureau, and other government agencies

The geographic distribution of population, economic activity and land use in Snohomish County is diverse, with a mix of rural and urban zones. For the most part, population centers in the county are oriented south in proximity to the border with King County and west along Interstate 5. By contrast, north and east Snohomish County are characterized by smaller town and cities, farmland and reservations.

The county ranks 13th statewide in terms of total land area (2,087.3 square miles) and is the 7th most densely populated county in Washington, with 401.53 people per square mile in 2021.

Local economy

Snohomish County has been and continues to be home to a number of Native American tribes. Early economic history of the county is characterized by an abundance of natural resources in a diverse ecological region.

European settlement of Puget Sound, including what is now Snohomish County, followed Captain George Vancouver’s claim of much of western Washington for Great Britain in 1792. Snohomish County was carved out of Island County in 1861 and the late 19th century saw the establishment of several settlements in western Snohomish County. The Great Northern Railway reached the newly-established city of Everett, bringing an economic boom to the area. Snohomish County’s early industrial economy thus continued to be based on the availability of abundant natural resources - primarily timber and farming.

Following World War II, Snohomish County’s economic growth expanded through the establishment of suburban cities oriented toward Seattle in the southwestern part of the county.

Home-grown multinational corporation, Boeing, traces its roots to the Seattle metropolitan area and continues to play a prominent role in Snohomish County’s economic make up. In the late 1960s, Boeing established its 747 manufacturing plant at Paine Field near Everett. The later development of other high technology industries in Snohomish County brought population increases and a shift from an economy based on logging and agriculture to one rooted in manufacturing and an expanding service sector.

Manufacturing continues to be a major economic driver in Snohomish County. About 50,000 jobs (18.1 percent of total Snohomish County nonfarm employment) in 2021 were in manufacturing industries. This is proportionally higher than any other county in Washington and above the national average. Although Snohomish County manufacturing is made up of many types of industries, aerospace products and parts manufacturing makes up the largest portion of employment. Aerospace manufacturers supplied 31,600 jobs in 2021. The manufacturing base, coupled with proximity to a major urban center, provides the foundation for a diverse local economy.

Other major industry sectors employing more than 20,000 included government (37,600), educational and health services (36,500), retail trade (34,000), professional and business services (28,300), leisure and hospitality (23,900) and construction (24,800).

In 2020, the COVID-19 pandemic-induced recession hit Snohomish County. Average annual total nonfarm employment dropped by 6.0 percent from 2019 to 2020, and began to recover as businesses, government and individuals navigated the new environment. In 2021, total nonfarm employment continued to fall an additional 0.4 percent: a reflection of layoffs in the manufacturing sector. As of April 2022 (preliminary), total nonfarm employment was estimated at 291,800 or 6.2 percent above the observed employment level 12 months earlier.

The leadup to the pandemic in Snohomish County was characterized by growth in most major industry sectors. During the 2020 pandemic, the industries that make up leisure and hospitality (e.g., restaurants, bars, hotels and entertainment venues) were the most severely impacted, while many of the region’s high tech and professional workers were able to shift their work environments temporarily, easing the impact.

The pandemic’s impact on manufacturing employment was delayed somewhat. From February 2020 to October 2021, Snohomish County’s manufacturing sector shed 13,700 jobs or 21.0 percent. Since October 2021, manufacturing employment has been expanding, however those losses put a damper on  Snohomish County’s recovery relative to the rest of the state.

From 2020 to 2021, average annual employment continued to drop, falling by 600 jobs or 0.56 percent. Losses were concentrated in manufacturing, reflected in net losses to the goods-producing sector, partially offset by employment gains in the service-providing sector. Now, with manufacturing declines behind it, the county is poised to continue to recover, bolstered by neighboring King County.
