Dallas

Dallas is a city in the U.S. state of Texas. Located in the state's northern region, it is the ninth-most populous city in the United States and third-most populous city in Texas, with a population of 1.3 million at the 2020 census. Along with the city of Fort Worth, Dallas anchors the Dallas–Fort Worth metroplex, the fourth-most populous metropolitan area in the U.S. and the most populous metropolitan area in Texas, at 8.5 million people. Dallas is a core city of the largest metropolitan area in the Southern U.S. and the largest inland metropolitan area in the U.S. that lacks any navigable link to the sea. It is the seat of Dallas County, covering nearly and extending into Collin, Denton, Kaufman, and Rockwall counties.

Both Dallas and nearby Fort Worth were initially developed as a product of the construction of major railroad lines through the area allowing access to cotton, cattle, and later oil in North and East Texas. The construction of the Interstate Highway System reinforced Dallas's prominence as a transportation hub, with four major interstate highways converging in the city and a fifth interstate loop around it. Dallas then developed as a strong industrial and financial center and a major inland port, due to the convergence of major railroad lines, interstate highways, and the construction of Dallas Fort Worth International Airport, one of the largest and busiest airports in the world. In addition, Dallas Area Rapid Transit (DART) operates rail and bus transit services throughout the city and its surrounding suburbs.
