Hillsboro

Hillsboro is a city in the U.S. state of Oregon and the county seat of Washington County. It lies in the Tualatin Valley on the west side of the Portland metropolitan area and is the fifth most populous city in Oregon, with 106,447 residents at the 2020 census. Settlers founded a community here in 1842, and it was later named for the Oregon politician David Hill. Riverboats on the Tualatin River, a railroad in the early 1870s and an interurban electric railway about four decades later supported slow growth to about 2,000 people by 1910. High-technology companies arrived in the 1980s, and the area is now known locally as the Silicon Forest, home to Intel. The city is run by a council and city manager, has more than twenty parks, ten National Register of Historic Places sites, light rail service and an airport, and also supports health care, retail and vineyards.
