Seattle anchors the Puget Sound region in King County, stretching from Northgate and Lake City in the north to Georgetown and Columbia City in the south, with neighborhoods like Ballard, Fremont, Capitol Hill, and West Seattle defining distinct pockets of the city. The metro area extends east through Bellevue and Redmond, north to Shoreline and Lynnwood, and south through Tukwila to SeaTac. The economy centers on technology, aerospace manufacturing, healthcare systems including UW Medicine and Swedish, the Port of Seattle, and the University of Washington, with a dense urban core surrounded by residential neighborhoods that climb the hills between Lake Washington and Elliott Bay.
