Mossy Creek is the historic name Jefferson City carried before its 1901 rename and still marks the community around the original mill site.<\/p>\n ZIP Codes<\/h2>\nMost of the smaller crossroads communities have no ZIP of their own and are served by the nearest post office town listed above.<\/p>\n Geography<\/h2>\nJefferson County sits in the ridge-and-valley country of East Tennessee, bounded by two impounded lakes: Douglas Lake, formed when the Tennessee Valley Authority dammed the French Broad River in the south of the county, and Cherokee Lake, formed by the damming of the Holston River in the north. Between the two lakes the land rises into low, rolling hills that give way to the foothills of the Great Smoky Mountains along the county’s southern edge. Of the county’s 314 square miles, 40 square miles (13 percent) are water.<\/p>\n The county borders Grainger County<\/a> to the north, Hamblen County<\/a> to the northeast, Cocke County<\/a> to the east, Sevier County<\/a> to the south, and Knox County<\/a> to the west.<\/p>\n Jefferson County had 54,683 residents at the 2020 census, up from earlier counts, giving a density of about 200 people per square mile of land. Jefferson City and Dandridge are the county’s two largest incorporated communities; the rest of the population is spread across unincorporated lakeside and rural areas. Jefferson County’s median household income runs below the Tennessee median of $67,631, reflecting the county’s mix of manufacturing, logistics, and agricultural employment rather than the higher-wage services found in nearby Knoxville.<\/p>\n Manufacturing, food processing, and logistics anchor the local economy. Bush Brothers & Company, the canned-bean maker, has deep roots in the county alongside the Jefferson County Board of Education and freight carrier Old Dominion Freight Line, each among the county’s largest employers. Carson-Newman University, a private Baptist university in Jefferson City, is the county’s principal higher-education institution and a major local employer in its own right. Douglas Lake draws seasonal boating, fishing, and lakefront tourism each summer, supplementing the county’s industrial base.<\/p>\n Jefferson County was established on June 11, 1792, by North Carolina territorial governor William Blount, and named for Thomas Jefferson, then U.S. Secretary of State. In the June 8, 1861 statewide referendum on secession, Jefferson County voters rejected leaving the Union by a margin of 1,987 to 603, part of the broader pro-Union sentiment across East Tennessee during the Civil War. Jefferson City, originally called Mossy Creek for the mill site around which it grew, took its present name in 1901.<\/p>\n Interstate 40 crosses the southern part of the county and Interstate 81 clips its northeastern corner, with US 11E, US 25E, US 25W, US 70, and US 411 serving as the main local highways.<\/p>\n The nearest commercial airport is McGhee Tyson Airport in Alcoa, southwest of Knoxville.<\/p>\n Where is Jefferson County, Tennessee?<\/strong> What is the population of Jefferson County?<\/strong> How big is Jefferson County?<\/strong> What is the county seat of Jefferson County?<\/strong> How many towns and cities are in Jefferson County?<\/strong> What ZIP codes are in Jefferson County?<\/strong> |
