Dallas is the third-largest city in Texas and the ninth-largest in the United States. Divided between Collin, Dallas, Denton, Kaufman, and Rockwall counties, the city had a 2010 population of approximately 1.2 million, according to the United States Census Bureau. The city is the largest economic center of the 12-county metropolitan area that according to the March 2010 U.S. Census Bureau release, had a population of roughly 6.5 million as of July 2009. The metropolitan area is the largest metropolitan area in the South and fourth-largest metropolitan area in the United States.
Dallas was founded in 1841 and formally incorporated as a city in February 1856. The city's economy is primarily based on banking, commerce, telecommunications, computer technology, energy, and transportation, home to several Fortune 500 companies. Located in North Texas and a major city in the American South, Dallas is the core of the largest inland metropolitan area in the United States that lacks any navigable link to the sea. The city's prominence arose from its historical importance as a center for the oil and cotton industries, and its position along numerous railroad lines. Dallas developed a strong industrial and financial sector, and a major inland port, due largely to the presence of Dallas/Fort Worth International Airport, one of the largest and busiest airports in the world. It was rated as a beta world city by the Globalization and World Cities Study Group & Network.More
In its beginnings, Dallas relied on farming, neighboring Fort Worth's Stockyards, and its prime location on Native American trade routes to sustain itself. Dallas' key to growth came in 1873 with the building of multiple rail lines through the city. As Dallas grew and technology developed, cotton became its boon and by 1900 Dallas was the largest inland cotton market in the world, becoming a leader in cotton gin machinery manufacturing. By the early 1900s Dallas was a hub for economic activity all over the southwestern United States and was selected in 1914 as the seat of the Eleventh Federal Reserve District. By 1925 Texas churned out more than ⅓ of the nation's cotton crop, with 31% of Texas cotton produced within a 100-mile (161 km) radius of Dallas. In the 1930s petroleum was discovered east of Dallas near Kilgore, Texas. Dallas' proximity to the discovery put it immediately at the center of the nation's petroleum market. Petroleum discoveries in the Permian Basin, the Panhandle, the Gulf Coast, and Oklahoma in the following years further solidified Dallas' position as the hub of the market.
The end of World War II left Dallas seeded with a nexus of communications, engineering, and production talent by companies such as Collins Radio Corporation. Decades later, the telecommunications and information revolutions still drive a large portion of the local economy. The city is sometimes referred to as the heart of "Silicon Prairie" because of a high concentration of telecommunications companies in the region, the epicenter of which lies along the Telecom Corridor located mostly in Richardson, a northern suburb of Dallas. The Corridor is home to more than 5,700 companies including Texas Instruments (headquartered in Dallas), Nortel Networks, Alcatel Lucent, AT&T, Ericsson, Fujitsu, Nokia, Rockwell Collins, Cisco Systems, Sprint, Verizon Communications, and until recently CompUSA (which is now headquartered in Miami,FL).More
