Dallas achieved the incorporation as a city when the railroad companies began to include it in their networks from 1872 on and it didn’t take long until Dallas became home to notable industries shortly thereafter. Also, it became one of the country’s most significant marketplaces for cotton around the turn of the century. Today, the mix of industroes is somewhat more diverse; especially companies from the fields of IT and telecommunications make their home in the region. The corporations headquartered here include AT&T, Verizon, Texas Instruments and Fujitsu. The metropolitan area has its transportation hub in one of the largest and busiest airports in the world. Dallas is also the US city with the most shopping centers per capita - a fact that’s adding to the remarkable revenues generated from tourism in the area, just as the vast Dallas Convention Center does, one of the largest conference venues in the country.
The Trinity River crosses through Dallas and the spot where it was easiest to pass through the river was used by John Neely Bryan in 1841 to establish a trading post housed in a simple wooden shack - the breeding ground for today’s megacity. The river, being 1100 kilometers in length flows through eastern Texas and finally empties into the Gulf of Mexico at the Galveston Bay. The city has a wet, sub-tropical climate that comes with summer temperatures that can be very high and mild winters that have two or three days of snow on average. Due to cold and warm fronts clashing during springtime, there are often violent thunderstorms, also tornadoes can occur this time of the year, as Dallas is located on the southern edge of Tornado Alley.
The town itself and the surroundings of the Metroplex, which include four other cities with more than 200,000 residents with Garland, Arlington, Irving and Plano as well as Fort Worth and numerous further towns, are a melting pot of global cultures. This finds an outlet in the area’s performing arts and music scene, but also in the culinary offerings and in the multitude of gathering places for many different religious denominations. About half of the residents of the city was not born in Texas; with a share of some 39% of the population, Mexican-born residents make up the largest share of these. About 30% of residents are Whites, 23% are Blacks. Also, many people with Asian heritage make their home in Greater Dallas. The average age of residents has been calculated as being 32 years.
