At the 2020 census, Dallas had a population of 1,304,379, up 106,563 from 2010. Recent estimates suggest a slight decline to 1,299,544 residents as of mid-2022. The city is part of the larger Dallas–Fort Worth metroplex, which contains roughly one-quarter of Texas’s population, making it the largest metropolitan area in the Southern U.S.

In 2020, there were 524,498 households in Dallas. About 36% were married couples, 57% were single householders with no spouse, and 36% were non-family households, often with residents living alone.
