Tulsa is the second-largest city in Oklahoma and the seat of Tulsa County, situated along the Arkansas River in the northeastern part of the state. With a 2020 census population of about 413,000, it anchors a metropolitan area of roughly 1.06 million people that also includes suburbs such as Broken Arrow and Jenks. The city's modern identity flows directly from its early-20th-century oil boom: the discovery of major oil fields around the turn of the century transformed a small trading post into a financial center once known as the "Oil Capital of the World." That boom-era wealth is visible throughout downtown. Tulsa holds one of the country's most significant collections of Art Deco architecture, much of it built between the mid-1920s and early 1940s, and the Oil Capital Historic District preserves dozens of National Register-listed buildings. The skyline's Deco towers and the Cesar Pelli-designed BOK Center arena mark a downtown that has remained the region's commercial and civic heart. Culturally, Tulsa is layered and distinctive. The Greenwood District, once a thriving Black business district known as Black Wall Street, and its 1921 history are commemorated at the Greenwood Rising history center, a defining element of the city's identity. The Philbrook Museum of Art occupies an Italianate villa with 25 acres of gardens, and the Gilcrease Museum houses a major collection of American West art. Route 66 passes through the city, adding another strand of heritage to its streetscape. Residentially, Tulsa spans a wide range of neighborhoods, from the historic homes of Midtown's Maple Ridge and the commercial corridors of Brookside and Cherry Street to newer suburban-style development on the south and east sides. The city's park system is anchored by Gathering Place, a free 66.5-acre riverfront park along the Arkansas River, and by the River Parks trails that follow the waterway. Tulsa suits households seeking a mid-sized city with genuine cultural institutions, a distinctive architectural character, and a comparatively easy commute — most parts of the city are reachable within a short drive. Its combination of oil-boom history, a revitalized arts scene, and riverside recreation gives it a profile unlike any other city in the region.
