The county’s smaller unincorporated communities have no ZIP of their own and are served by the nearest listed town.<\/p>\n Geography<\/h2>\nGrayson County sits at the northern edge of the Blackland Prairie, where it meets the Eastern Cross Timbers along the Red River. The Red River and Lake Texoma, formed by the Denison Dam, form most of the county’s northern boundary with Oklahoma; the Hagerman National Wildlife Refuge occupies a peninsula on the lake near Sherman. The rest of the county is gently rolling prairie and post-oak woodland drained by Iron Ore Creek, Choctaw Creek, and the Sister Grove and Bois d’Arc creeks in the south.<\/p>\n Grayson County borders Fannin County<\/a> to the east, Collin County<\/a> to the south, Denton County<\/a> to the southwest, Cooke County<\/a> to the west, and Marshall County<\/a> and Love County across the Red River to the north and northwest, with Bryan County, Oklahoma touching its northeastern corner.<\/p>\n Grayson County had a population of 135,543 at the 2020 census, a density of about 145 people per square mile. Sherman and Denison, its two largest cities, together account for roughly half the county’s population and anchor the Sherman–Denison metropolitan statistical area. Household income varies widely between the growing Sherman-Denison corridor and the county’s rural townships; the county is compared here against the Texas median of $75,780, published in the Census Bureau’s 2023 American Community Survey.<\/p>\n Semiconductor manufacturing is the county’s largest single employer: Texas Instruments operates a wafer fabrication plant in Sherman that has anchored the local economy since the 1960s. Tyson Foods runs a poultry processing plant in Sherman, and Grayson College, based in Denison with a Sherman campus, is the county’s community college. Lake Texoma draws recreational boating and fishing traffic from across North Texas and Oklahoma, and the county still hosts working cattle ranches and grain farms outside the Sherman-Denison urban core.<\/p>\n Grayson County was organized in 1846 from Fannin County and named for Peter Wagener Grayson, an attorney general of the Republic of Texas who died in 1838. Sherman, platted the same year, became the county seat. Denison was founded in 1872 as a railhead of the Missouri-Kansas-Texas Railroad (“the Katy”) at its crossing of the Red River, and is the birthplace of President Dwight D. Eisenhower, born there on October 14, 1890; his birthplace home is preserved as a state historic site.<\/p>\n US Highway 75 runs north–south through Sherman and Denison toward the Oklahoma state line at Denison Dam; US 82 crosses the county east–west, and US 69 and State Highway 91 serve the eastern towns.<\/p>\n North Texas Regional Airport, between Sherman and Denison, handles general aviation; the nearest major commercial airport is Dallas Fort Worth International, about 60 miles south.<\/p>\n Where is Grayson County, Texas?<\/strong> What is the population of Grayson County?<\/strong> How big is Grayson County?<\/strong> What is the Grayson County seat?<\/strong> How many towns are in Grayson County?<\/strong> What ZIP codes are in Grayson County?<\/strong> |
