POPULATION

Thurston County has been one of the fastest-growing counties in Washington State since the 1960s, exceeding the state’s overall rate of growth consistently.

For Thurston County, population growth has little to do with increased rates of birth. Instead, the majority of population increase has been due to the migration of people into the county. It is the result of a relatively stable economy, high quality of life, and a lower cost of living than in counties to the north.

CLIMATE

Thurston County is located at the southern tip of Puget Sound and is known for its fair-weather summers and gray, wet winters. Locals recognize that this balance is responsible for the acclaimed beauty of this region. The mild, marine-type climate allows for outdoor activities including biking, hiking, gardening and boating year-round.

Like most of western Washington, Thurston County’s weather is characterized by sunny summers and wet winters.
