Lewis County profile


Regional context

Lewis County, located in southwestern Washington, is the sixth largest county in the state. The Chehalis and Cowlitz rivers are the two major rivers in the county. Lewis, named for Meriwether Lewis, was created as a county in 1845. Its original borders encompassed half of Washington state and British Columbia. The Chehalis and Meshall tribal people inhabited this area prior to white explorers and settlers, but their numbers were decimated by disease. Many of these settlers worked in the trading posts as well as the Hudson Bay commercial farm that provided the trading posts.

Local economy

Once the railroad was established, logging and milling attracted immigrants and in-migrants. Labor organizers were outraged by the unsafe working conditions and low wages in this industry. In 1919, a gun battle erupted between members of the Industrial Workers of the World (IWW) and some World War I veterans and is known as the “Centralia Massacre”.

The 1920s brought hard times to Lewis before the Great Depression took hold. World War II increased the demand for wood and farm products, lifting the Lewis County economy again. Its economy has continued boom and bust cycles over its history.

The recession was difficult on the Lewis county economy, as nonfarm payrolls dropped and double digit unemployment rates were the rule rather than the exception. Now, nearly 10 years removed from the downturn, nonfarm payrolls are expanding and the unemployment rates in the county are at historic lows. Taxable sales for all industries are up over 31 percent since 2010. Newfound optimism has spurred development and job creation in construction, trade and leisure and hospitality.

Labor force and unemployment

Current labor force and unemployment statistics are available on the Labor area summaries page.

Annual average unemployment in Lewis County has been declining since the 13.3 percent rate posted in 2009. In 2019 that streak ended, as unemployment rose from 6.3 percent in 2018 to 6.5 percent in 2019. In 2017 the rate was 6.6 percent.

Since 2014, the labor force in the county has steadily grown, up nearly 4,000 above 2014 totals. This gain in the labor force may indicate a continued faith in the local economy as well as a more positive job market.
