Dallas is part of the fourth largest metropolitan area in the United States (by population), the Dallas-Fort Worth Metroplex. Most of the homes available in Dallas are single-family dwellings, but townhomes, condominiums and multi-family buildings are also available. There is some new construction, but the majority of existing houses were built between 1975 and 2005. About half of all homes currently for sale in Dallas are 1,500 square feet or larger.
Central Dallas is made up of the Oak Lawn, Uptown and Downtown neighborhoods, all of which are vibrant centers of retail shopping, dining and nightlife. The Downtown area itself is made up of several smaller districts, including the Farmers Market District, the Arts District and the West End Historic District. Hollywood Heights/Santa Monica is a conservation district in East Dallas, known for its pre-World War II Tudor-style homes. It is near Tennison Park Golf Course and the Dallas Arboretum and Botanical Garden. Another historic district in East Dallas is known for its Prairie-style homes, inspired by the architecture of Frank Lloyd Wright. The Cedars District, located in South Dallas, is known as an artists’ area, the Bishop Arts District is a small commercial district just south of Downtown, and several suburbs surround the city itself.
The Dallas-Fort Worth area is sometimes referred to as "Silicon Prairie" because of the surprising number of tech and communications companies that have established their headquarters there. Some major employers in the Metroplex are AT&T, Texas Instruments, Affiliated Computer Services, Verizon Communications, Cisco Systems, Nokia and Sprint. Other companies based in the area are American Airlines, Southwest Airlines, Kimberly-Clark, Radio Shack, Exxon Mobil, Dr Pepper, GameStop, 7-Eleven, Borden Milk Products and J.C. Penney. In addition to its corporate headquarters, Texas Instruments operates manufacturing plants in Dallas, employing more than 10,000 workers and positioning the company as a major supplier of jobs in the area.
