The city is home to the third-largest concentration of Fortune 500 companies in the nation (behind New York City and Houston).Dallas and nearby Fort Worth were developed due to the construction of major railroad lines through the area allowing access to cotton, cattle, and later oil in North and East Texas.The city is the largest economic center of the 12-county Dallas–Fort Worth–Arlington metropolitan area (commonly referred to as DFW), which had a population of 7,102,796 as of July 1, 2015, representing growth in excess of 676,000 people since the 2010 census.As such, the metropolitan area's economy is the 10th largest in the world."Hot spots" in this area include Uptown, Victory Park, Oak Lawn, Dallas Design District, Trinity Groves, Turtle Creek, Cityplace, Knox/Henderson, Greenville and West Village.East Dallas is home to Deep Ellum, a trendy arts area close to Downtown, the homey Lakewood neighborhood (and adjacent areas, including Lakewood Heights, Wilshire Heights, Lower Greenville, Junius Heights, and Hollywood Heights/Santa Monica), historic Vickery Place and Bryan Place, and the architecturally significant neighborhoods of Swiss Avenue and Munger Place.With construction of railroads, Dallas became a business and trading center, and was booming by the end of the 19th century.
The bulk of the city is in Dallas County, of which it is the county seat; however, sections of the city are located in Collin, Denton, Kaufman, and Rockwall counties.
Although some of Dallas' architecture dates from the late 19th and early 20th centuries, most of the notable architecture in the city is from the modernist and postmodernist eras. Several smaller structures are fashioned in the Gothic Revival style, such as the Kirby Building, and the neoclassical style, as seen in the Davis and Wilson Buildings.
Iconic examples of modernist architecture include Reunion Tower, the JFK Memorial, I. One architectural "hotbed" in the city is a stretch of historic houses along Swiss Avenue, which contains all shades and variants of architecture from Victorian to neoclassical.
