Economy
In its beginnings, Dallas relied on farming, neighboring Fort Worth's cattle market, and its prime location on trade routes with Indians to sustain itself. Dallas's real key to growth came in 1873 though with the building of multiple rail lines through the city. As Dallas grew and technology developed, cotton became its boon—by 1900 Dallas was the largest inland cotton market on Earth and led the world 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, and 31% of Texas cotton was produced within a 100 mile (161 km) radius of Dallas. In the 1930s, oil was discovered east of Dallas near Kilgore, Texas, and Dallas's proximity to the discovery put it at the center of the nation's oil market. Oil discoveries in the Permian Basin, the Panhandle, the Gulf Coast, and Oklahoma in the following years further solidified Dallas's position as the hub of the market as it was roughly the geographic center of all 5 regions.

After World War II, Dallas was seeded with a nexus of communications engineering and production talent by companies such as Collins Radio Corp. The telecommunication and information revolutions that ensued still drive a great deal of the local economy. The city is sometimes referred to as Texas's Silicon Valley or the Silicon Prairie because of a high concentration of telecommunications companies—the epicenter of which lies along the “Telecom Corridor”, home to more than 5,700 companies. The corridor is also home to Texas Instruments and regional offices for Alcatel Lucent, AT&T, Ericsson, Fujitsu, MCI, Nokia, Rockwell, Sprint, and Verizon, as well as the national offices of CompUSA and Canadian Nortel.

In the 1980s, Dallas was a real estate hotbed, with populations skyrocketing and the demand for housing and jobs soaring along with it. Downtown Dallas's largest buildings are the fruit of this boom, but over-speculation and the Savings and Loan crisis knocked the area to its knees. Between the late 1980s and the early 2000s, Dallas suffered a lengthy recession and has only recently bounced back—like much of the country, the real estate market has improved significantly in recent years.

Dallas is no longer a hotbed for manufacturing like it was in the early 20th century—partially due to constraints placed by the DFW Ozone Nonattainment Area—but plenty of goods are still manufactured in the city. Texas Instruments employs 10,400 people at its corporate headquarters and chip plants in Dallas and neighboring Richardson. Oak Farms Dairy also headquarters and has a plant in the city.

Companies headquartered in Dallas, Irving or Mesquite include ExxonMobil, the largest company in the world (by revenue), 7-Eleven, Brinker International, id Software, Blockbuster, ENSCO Offshore Drilling, Kimberly-Clark, Energy Future Holdings Corporation, Mary Kay Cosmetics, Southwest Airlines, CompUSA, Texas Instruments, Fluor, Zales and Comerica Bank. Corporate headquarters in the northern suburb of Plano include EDS, Frito Lay, Dr Pepper, and JCPenney.

The Dallas metroplex has more shopping centers per capita than any other United States city or metro, and is also home to the second shopping center in the United States, Highland Park Village, which opened in 1931. The city itself is also home to 12 billionaires—concentrated in the Preston Hollow area of north Dallas—placing it 9th worldwide among cities with the most billionaires. When combined with the 8 billionaires who live in Dallas's neighboring city of Fort Worth, the Dallas-Fort Worth Metroplex is one of the greatest concentrations of billionaires in the world.

Attractions
Cuisine
Dallas is renowned for barbecue, authentic Mexican, and Tex-Mex cuisine. Famous products of the Dallas culinary scene include the frozen margarita and the restaurants La Calle Doce, Sonny Bryan's Smokehouse, Enchilada's, Mi Cocina, Bone Daddy's Barbecue, and The Mansion on Turtle Creek. The French Room at the Hotel Adolphus in downtown Dallas was named the best hotel restaurant in the US by Zagat. Several nationally ranked steak and chop houses can be found in the Dallas area including Bob's Steak & Chop House which is currently ranked #3 according to the USDA Prime Steakhouses chart. On average, Dallasites eat out about four times every week, which is the third highest rate in the country, behind Houston and Austin, and Dallas has more restaurants per capita than New York City.

Arts
The Arts District in downtown is home to several arts venues, both existing and proposed. Notable venues in the district include the Dallas Museum of Art, the Morton H. Meyerson Symphony Center, The Trammell & Margaret Crow Collection of Asian Art, the Nasher Sculpture Center,The Dallas Contemporary, The Dallas Children's Theatre. Venues under construction or planned include the Winspear Opera House and the Dallas Center for the Performing Arts. The district is also home to DISD's Booker T. Washington High School for the Performing and Visual Arts, which is currently being expanded.

Deep Ellum originally became popular during the 1920s and 1930s as the prime jazz and blues hotspot in the south. Artists such as Blind Lemon Jefferson, Robert Johnson, Huddie “Leadbelly” Ledbetter, and Bessie Smith played in original Deep Ellum clubs such as The Harlem and The Palace. Today, Deep Ellum is home to hundreds of artists who live in lofts and operate in studios throughout the district alongside bars, pubs, and concert venues. One major art infusion in the area is the city's lax stance on graffiti; consequently, several public ways including tunnels, sides of buildings, sidewalks, and streets are covered in murals. One major example, the Good-Latimer tunnel, was torn down in late 2006 to accommodate the construction of a light rail line through the site.

The Cedars has a growing population of studio artists and an expanding roster of entertainment venues. The area's art scene began to grow in the early 2000s with the opening of Southside on Lamar, a Sears warehouse converted into lofts, studios, and retail. Current attractions include Gilley's Dallas and Poor David's Pub. Entrepreneur Mark Cuban purchased land along Lamar Avenue near Cedars Station in September 2005 and locals speculate that he is planning an entertainment complex for the site.

The Bishop Arts District in Oak Cliff is home to a number of studio artists living in converted warehouses. Walls of buildings along alleyways and streets are painted with murals and the surrounding streets contain many eclectic restaurants and shops.

Dallas has an Office of Cultural Affairs as a department of the city government. The City of Dallas Office of Cultural Affairs is responsible for six cultural centers located throughout the city, funding for local artists and theatres, public art projects and running the city owned radio station WRR.

The fair is a massive event for the state of Texas and brings an estimated US$350 million to the city's economy annually. The Red River Shootout (UT-OU) game at the Cotton Bowl and other Cotton Bowl games also bring significant crowds to the city.

Other festivals in the area include Cinco de Mayo festivities hosted by the city's large Mexican population, Saint Patrick's Day parades in Irish communities especially along east Dallas's Lower Greenville Avenue, Juneteenth festivities, the Greek Food Festival of Dallas, and an annual Halloween parade on Cedar Springs Road.

Small portions of the Allen city limits extend into Lovejoy, McKinney, and Plano ISDs. In the fall of 2006, new 9th grade high school students in the Lovejoy ISD boundaries began attending the newly opened Lovejoy High School. A new grade level is to be added each subsequent school year, making the school a full 4-year high school in the 2009-10 school year. Existing Allen High School (Classes 2008 and 2009) students within the Lovejoy ISD boundaries continue to attend Allen High School.

Allen hosts a campus of the Collin County Community College District, which is located inside Allen High School.

The Allen Eagle Escadrille, Allen High School's marching band, performed in the 2006 Tournament of Roses Parade and Bandfest in Pasadena, California. The Escadrille has 650 members, including the band, drill team, and color guard. The Escadrille is the largest high school band in the world. It was also a special participant in the 1994 St. Patrick's Day Parade in Dublin, Ireland, 1995 and 1999 Texas Gubernatorial Parades, and 1997 Macy's Thanksgiving Day Parade in New York City.

Transportation
