Of its 726 square miles, 724 are<br \/>\nland and 2.2 are water, about 0.3 percent &mdash; the county has no large natural lake. Henry<br \/>\nHagg Lake, a reservoir southwest of Forest Grove, is the county&#8217;s largest body of water, and the<br \/>\nTualatin River, which drains most of the valley floor, is its principal river.<\/p>\n<p>Clatsop County lies to the northwest, Columbia County to the north, Multnomah County to the<br \/>\neast, Clackamas County to the southeast, Yamhill County to the south, and Tillamook County to the<br \/>\nwest. <a href=\"https:\/\/townsvillages.com\/us\/clatsop-county\/\">Clatsop County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/columbia-county-oregon\/\">Columbia County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/multnomah-county\/\">Multnomah County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/clackamas-county\/\">Clackamas County<\/a>, <a\nhref=\"https:\/\/townsvillages.com\/us\/yamhill-county\/\">Yamhill County<\/a> and <a\nhref=\"https:\/\/townsvillages.com\/us\/tillamook-county\/\">Tillamook County<\/a> all border Washington<br \/>\nCounty directly.<\/p>\n<h2>Demographics<\/h2>\n<p>Washington County had a population of 600,372 at the 2020 census, the second-highest total of<br \/>\nOregon&#8217;s 36 counties, and the latest estimate puts the county near 611,708 residents. Hillsboro<br \/>\nand Beaverton are by far the two largest communities, together holding well over a third of the<br \/>\ncounty&#8217;s population. Median household income runs $107,772 (2024), well above Oregon&#8217;s statewide<br \/>\nfigure of $80,160 (2023 ACS). Population density works out to roughly 829 people per square mile<br \/>\nof land, among the densest counties in the state outside Multnomah.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Manufacturing employs the most workers in the county, about 56,438 people, followed by health<br \/>\ncare and social assistance at 40,956 and retail trade at 37,328. That manufacturing weight comes<br \/>\nfrom the Silicon Forest, the semiconductor and electronics cluster centered on the<br \/>\nBeaverton-Hillsboro corridor since the 1970s. Intel employs roughly 22,000 people across its<br \/>\nHillsboro campuses, its largest concentration of employees anywhere. Nike&#8217;s world headquarters<br \/>\nsits on an unincorporated Washington County campus surrounded by the city of Beaverton. Forest<br \/>\nGrove is home to Pacific University, and Hillsboro Airport, the county&#8217;s general-aviation field,<br \/>\nhosts the Oregon International Air Show each summer. Hillsboro&#8217;s Fourth of July Parade is the<br \/>\nsecond-largest Independence Day parade in Oregon.<\/p>\n<h2>History<\/h2>\n<p>The Atfalati, a band of the Tualatin Kalapuya, lived in the Tualatin Valley before white<br \/>\nsettlement. The Oregon provisional government created Twality District on 5 July 1843, one of the<br \/>\noriginal four districts of the Oregon Country. The Oregon Territorial Legislature renamed it<br \/>\nWashington County, after George Washington, in 1849.<\/p>\n<p>Hillsboro was incorporated on 19 October 1876 and named for David Hill, an early Oregon<br \/>\npolitician who sold part of his land claim to the county in 1850. Forest Grove, settled in the<br \/>\n1840s and incorporated in 1872, was the first city organized in the county and is now home to<br \/>\nPacific University, founded the same decade. Cornelius traces to an 1845 settlement originally<br \/>\ncalled Free Orchards, renamed in 1893 for Thomas R. Cornelius, who built the town around a<br \/>\nplanned rail line.<\/p>\n<h2>Getting There<\/h2>\n<p>US Route 26 crosses the county&#8217;s north side through Hillsboro and Beaverton. Oregon Routes 6, 8,<br \/>\n10, 47, 99W, 210, 217 and 219 also run through the county; Interstate 5 and Interstate 205 touch<br \/>\nits southeastern corner near Tualatin and Lake Oswego.<\/p>\n<ul>\n<li>Portland &mdash; about 12 miles east<\/li>\n<li>Salem &mdash; about 45 miles south<\/li>\n<li>McMinnville &mdash; about 25 miles southwest<\/li>\n<li>Vancouver, Washington &mdash; about 20 miles northeast<\/li>\n<\/ul>\n<p>Portland International Airport, about 20 miles east of Hillsboro, is the nearest major<br \/>\ncommercial airport.
