Overview

Regional context


King County is situated between Puget Sound to the west and the crest line of the Cascade Range to the east. It borders Snohomish County to the north and Pierce County to the south. King County has points at sea level and a high point of nearly 8,000 feet.

King County and Seattle, the county seat, are the most populous county and city in Washington state. King County ranks 11th in the state in terms of land area and first in the state for population density.

Local economy

Lumber played a major role in King County’s early history, especially before the Great Seattle Fire of 1889. Seattle also served as an important stopping point for those hoping to prospect in Alaska. In more recent decades, the region was highly dependent on the aerospace industry. Aerospace still plays an important role, but a much smaller percentage of workers have specialized in the industry over the past 10 years.

Throughout the 1990s, the county underwent extraordinary gains in employment, population and wages. Despite the county’s increasing cost of living, especially in housing, the high-tech job boom lured well-educated newcomers to the area. The county continues to hold a strong national reputation as a hub for information technology development.

In 2005, the county was renamed in honor of Dr. Martin Luther King, Jr. The area is culturally diverse and aims to be a place where people from a variety of backgrounds can feel at home. King County has an active port, maintaining extensive connections to East Asian markets.

Today, the King County economy is still recovering from the 2007 recession, although the local recovery is leading the statewide recovery and is more promising than that seen nationwide. King County’s labor market peaked in 2008 when annual average total nonfarm employment was in excess of 1.2 million. Employment levels hit bottom in 2010, but have been on the upswing ever since. For the past several months, employment levels have, once again, entered the 1.2 million range.

Major industry sectors in King County with more than 100,000 estimated jobs include professional, scientific and technical services, government, education and health services, leisure and hospitality, retail trade and manufacturing.

The unemployment rate in King County has been steadily and consistently declining since reaching a peak level of 9.6 percent in early 2010. Throughout the recession and recovery, King County’s unemployment rate has been lower than that of Washington state. As of June 2013, the not seasonally adjusted unemployment rate in King County was 5.2 percent.

Outlook

It will take time to rebuild the economy, but the local outlook is showing very hopeful signs. The recovery has looked very different depending on where one lives; and King County has been at the center of the statewide recovery. All major sectors have experienced positive employment growth, albeit to varying degrees. Industries reporting the largest post-recession gains include professional and business services, retail trade, manufacturing and wholesale trade.

King County’s early recovery was driven in large part by manufacturing and professional and business services. In recent months, growth has shifted to professional and business services, retail and leisure and hospitality. Government payrolls have been declining in light of weak revenues. Manufacturing employment has slowed and projections continue to fluctuate depending on aerospace announcements. Aircraft production at Renton is expected to continue into the future.
