Carrollton is a city in the Dallas-Fort Worth metroplex, notable for lying within three counties: Dallas, Denton, and Collin. Situated northwest of Dallas, it is one of the region's larger and more established inner-ring suburbs, with about 133,000 residents. The area's history reaches back to the 1850s, when the settlement of Trinity Mills grew up around a gristmill on the Elm Fork of the Trinity River, and the town of Carrollton took shape around a railroad stop. Today Trinity Mills lives on as a rail hub, while Downtown Carrollton preserves the city's early commercial core. That layered history — mill town, railroad town, and modern suburb — still shapes Carrollton's geography. Carrollton has become one of the metroplex's most culturally diverse cities. It is home to the largest Korean community in Texas and the southern United States, and the Koreatown district along Old Denton Road is a nationally recognized concentration of Korean and broader Asian restaurants, grocery stores, and shops. Vietnamese, Indian, Chinese, and Latino communities add to the city's demographic and culinary richness. The city is also unusually well connected by rail for a Texas suburb. DART's Green Line serves Downtown Carrollton, North Carrollton/Frankford, and Trinity Mills stations, providing direct access to downtown Dallas, while the DCTA A-train links Trinity Mills to Denton County. The Elm Fork of the Trinity River adds paddling and parkland within the city. Carrollton suits residents seeking a mature, diverse suburb with strong transit links, a deep food scene, and housing that spans established neighborhoods and newer master-planned communities. Its central location offers convenient access to the employment centers, airports, and amenities of the broader metroplex.
