Dallas

Dallas is the third-largest city in Texas and the ninth-largest in the United States. As of June 22, 2010 the population of Dallas was at 1.3 million according to the US Census Bureau. The city is the largest economic center of the 12-county Dallas–Fort Worth–Arlington metropolitan area that according to the March 2010 U.S. Census Bureau release, had a population of 6.45 million as of July 2009. The metropolitan area is the fourth-largest metropolitan area in the United States.

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; only New York City and Houston are home to more Fortune 500 headquarters in the city limits. 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 despite this comes from its historical importance as a center for the oil and cotton industries, its position along numerous railroad lines, a strong industrial and financial sector, and its status as a major inland port (due largely to the presence of Dallas/Fort Worth International Airport, one of the largest and busiest in the world). It was rated as a beta world city by the Globalization and World Cities Study Group & Network.

Dallas has a humid subtropical climate, though it is located in a region that also tends to receive warm, dry winds from the north and west in the summer, bringing temperatures well over 100 °F (38 °C) at times and heat-humidity indexes soaring to as high as 117 °F (47 °C). When only temperature itself is accounted for, the north central Texas region where Dallas is located is one of the hottest in the United States during the summer months, usually trailing only the Mojave Desert basin of Arizona, southern Nevada, and southeastern California.
