Dallas–Fort Worth metroplex

The Dallas–Fort Worth metroplex, officially designated Dallas–Fort Worth–Arlington by the U.S. Office of Management and Budget, is the most populous metropolitan statistical area in the U.S. state of Texas and the Southern U.S., encompassing 11 counties. Its historically dominant core cities are Dallas and Fort Worth. It is the economic and cultural hub of North Texas. Residents of the area also refer to it as DFW (the code for Dallas Fort Worth International Airport) or the Metroplex. The Dallas–Fort Worth–Arlington metropolitan statistical area's population was 7,637,387 according to the U.S. Census Bureau's 2020 census, making it the fourth-largest metropolitan area in the U.S. and the eleventh-largest in the Americas. In 2016, the Dallas–Fort Worth metroplex had the highest annual population growth in the United States. By 2023, the U.S. Census Bureau estimated that the Dallas-Fort Worth metropolitan area's population had increased to 8,100,037, with the highest numerical growth of any metropolitan area in the United States.

The metropolitan region's economy, also referred to as Silicon Prairie, is primarily based on banking, commerce, insurance, telecommunications, technology, energy, healthcare, medical research, transportation, manufacturing, and logistics. As of 2022, Dallas–Fort Worth is home to 23 Fortune 500 companies, the 4th-largest concentration of Fortune 500 companies in the United States behind New York City (62), Chicago (35), and Houston (24). In 2016, the metropolitan economy surpassed Houston, the second largest metro area in Texas, to become the fourth-largest in the U.S. The Dallas–Fort Worth metroplex boasted a GDP of just over $620.6 billion in 2020 (although both metropolitan regions have switched places multiple times since GDP began recording). If the Metroplex were a sovereign state, it would have the twentieth largest economy in the world as of 2019. In 2015, the conurbated metropolitan area would rank the ninth-largest economy if it were a U.S. state. In 2020, Dallas–Fort Worth was recognized as the 36th best metropolitan area for STEM professionals in the U.S.
