Tri-Cities, Washington

The Tri-Cities are three closely linked cities (Kennewick, Pasco, and Richland) at the confluence of the Yakima, Snake, and Columbia Rivers in the Columbia Basin of Eastern Washington. The cities border one another, making the Tri-Cities seem like one uninterrupted mid-sized city. The three cities function as the center of the Tri-Cities metropolitan area, which consists of Benton and Franklin counties. The Tri-Cities urban area consists of the city of West Richland, the census-designated places (CDP) of West Pasco, Washington and Finley, as well as the CDP of Burbank, despite the latter being located in Walla Walla County.

The official 2016 estimate of the Tri-Cities MSA population is 283,869, a more than 12% increase from 2010. 2016 U.S. MSA estimates show the Tri-Cities population as over 300,000. The combined population of the three principal cities themselves was 220,959 at the 2020 census. As of April 1, 2021, the Washington State Office of Financial Management, Forecasting Division estimates the cities as having a combined population of 224,640.

The Tri-Cities Airport is located in Pasco and provides the region with commercial and private air service. Pasco is the seat of Franklin County, while the other two cities are located in Benton County. In 2010, Kiplinger rated the Tri-Cities among the Top 10 best places to raise a family, and CNN/Money ranked the Tri-Cities one of the top 10 best bets for gains in housing value, due to its relatively stable economic conditions since the early 2000s.
