Population density is about 20 people per square mile, reflecting the county’s rural, heavily forested character.<\/p>\n Timber and forestry dominate the local economy, tied to the Davy Crockett National Forest and surrounding private pine plantations.

Local government, healthcare, and retail centered on Groveton round out employment.<\/p>\n Trinity County was organized in 1850 and named for the Trinity River, which forms its western border. The county’s early economy centered on sawmilling and cotton farming; the arrival of the railroad in the late 19th century spurred towns like Trinity and Groveton. Much of the county’s eastern timberland was later folded into the Davy Crockett National Forest, established in 1936 as part of federal reforestation efforts following decades of heavy logging.<\/p>\n U.S. Highway 287 and State Highway 94 are the county’s main routes, meeting at Groveton.<\/p>\n The nearest commercial airport is George Bush Intercontinental Airport in Houston, about 90 miles to the south.<\/p>\n Where is Trinity County, Texas?<\/strong> What is the population of Trinity County?<\/strong> How big is Trinity County?<\/strong> What is the county seat of Trinity County?<\/strong> How many towns are in Trinity County?<\/strong>\n\n
