Starr County is a county in Texas, United States, on the international border with Mexico along the Rio Grande, across from the Tamaulipas municipalities of Camargo, Gustavo Díaz Ordaz, Mier and Miguel Alemán. It had a population of 65,920 at the 2020 census and covers 1,312 square miles (3,399 km2) centred near 26°34′N 98°44′W.<\/p>\n
Rio Grande City is the county seat and its postal code is 78582. The county has three incorporated cities and towns — Rio Grande City, Roma and La Grulla — plus roughly 55 colonias and other unincorporated communities, all in the Central time zone. Starr County’s FIPS code is 48427.<\/p>\n
Rio Grande City, Roma and La Grulla are the county’s only incorporated places; Escobares is a census-designated place. The rest of the county’s roughly 190 named settlements are unincorporated colonias — small residential subdivisions, many platted decades ago along the river road corridor without water, sewer or paved-street service at the time of settlement. The table below carries over the full roster from the county’s earlier settlement list, with duplicate spellings and repeated “Colonia” suffixes merged into a single entry per place. Most colonias have no separate population count or ZIP code in Census Bureau or postal data and are marked with a dash.<\/p>\n

The terrain rises gradually away from the river into semi-arid rangeland covered in mesquite, huisache and prickly pear. Falcon Lake, formed by the Falcon Dam on the Rio Grande, occupies part of the county’s western edge and supplies irrigation water and recreation.<\/p>\n Starr County borders Zapata County<\/a> to the northwest, Jim Hogg County<\/a> to the north, Brooks County<\/a> to the northeast, and Hidalgo County<\/a> to the east; its entire southern and western edge is the international border with Mexico’s Tamaulipas state.<\/p>\n Starr County had 65,920 residents at the 2020 census. Rio Grande City (15,146) and Roma (9,886) are the two largest communities, together holding more than a third of the county’s population. The county’s median household income trails the Texas median of $75,780 by a wide margin, reflecting its status as one of the state’s lowest-income counties. At 65,920 people over roughly 1,223 square miles of land, density is about 54 people per square mile, concentrated along the river-road corridor between Rio Grande City and Roma rather than spread evenly across the ranchland to the north.<\/p>\n Agriculture remains central to the county’s economy, and Starr is one of Texas’s leading producers of oilseeds and dry beans. Public-sector employment through the three school districts — Rio Grande City Consolidated ISD, Roma ISD and San Isidro ISD — and county and municipal government is a major source of jobs, alongside retail and services clustered in Rio Grande City and Roma. South Texas College serves the county’s higher-education needs. Cross-border trade and travel with Camargo, Miguel Alemán and other Tamaulipas towns shapes daily commerce along the river.<\/p>\n Starr County was organized in 1848, the year after the Mexican-American War ended, and named for James Harper Starr, secretary of the treasury of the Republic of Texas. Its settlements grew out of Spanish colonial-era ranching grants along the Rio Grande, and Roma’s downtown historic district still preserves 19th-century sandstone architecture from its days as a river port. For more than a century the county voted overwhelmingly Democratic in presidential elections; that pattern ended in 2024.<\/p>\n U.S. Route 83 runs the length of the county along the river, connecting Rio Grande City and Roma to Laredo to the northwest and the Rio Grande Valley cities to the southeast.<\/p>\n The nearest commercial airport is McAllen Miller International Airport in Hidalgo County.<\/p>\n Where is Starr County?<\/strong> What is the population of Starr County?<\/strong> How big is Starr County?<\/strong> What is the Starr County seat?<\/strong> How many towns are in Starr County?<\/strong> What ZIP codes are in Starr County?<\/strong> |
