Franklin and Spring Hill are the two largest<br \/>\ncommunities, together holding well over a third of the county&#8217;s population. Median household<br \/>\nincome runs among the highest of any county in the United States, well above Tennessee&#8217;s<br \/>\nstatewide figure of $67,631 (2023 ACS). Population density works out to roughly 425 people per<br \/>\nsquare mile of land, high for Middle Tennessee outside Davidson County, reflecting the<br \/>\ncounty&#8217;s position inside the Nashville-Davidson-Murfreesboro-Franklin metropolitan area.<\/p>\n<h2>Economy &amp; Local Life<\/h2>\n<p>Health care employs a large share of the county&#8217;s workforce, led by Community Health<br \/>\nSystems, headquartered in Franklin with 3,923 local employees, and Williamson Medical Center with<br \/>\n1,900. Nissan North America runs a major operations campus in Franklin employing 1,550 people,<br \/>\nand Lee Company, a mechanical and facility-services firm, employs 1,616. In Spring Hill, General<br \/>\nMotors&#8217; assembly and powertrain plant is the county&#8217;s largest manufacturing employer,<br \/>\nnow paired with an Ultium Cells battery plant that began operating in 2024. Franklin&#8217;s<br \/>\nCool Springs corridor anchors much of the county&#8217;s retail and office employment. The<br \/>\ncounty&#8217;s biggest annual event is the Pilgrimage Music and Cultural Festival in Franklin each<br \/>\nlate September, which draws tens of thousands of visitors over a single weekend.<\/p>\n<h2>History<\/h2>\n<p>The Tennessee General Assembly established Williamson County on October 26, 1799, carving it<br \/>\nout of Davidson County. It was named for Hugh Williamson, a North Carolina physician and<br \/>\npolitician who served three terms in the Continental Congress and helped draft the U.S.<br \/>\nConstitution. Franklin was founded the same year by Abram Maury Jr. and named for Benjamin<br \/>\nFranklin.<\/p>\n<p>The county saw three Civil War engagements, the largest being the Second Battle of Franklin on<br \/>\nNovember 30, 1864, which produced nearly 10,000 casualties in a single afternoon. McGavock<br \/>\nConfederate Cemetery, next to the Carnton plantation house near Franklin, holds 1,481 soldiers and<br \/>\nis the largest private Confederate cemetery in the country. A third engagement, the Battle of<br \/>\nThompson&#8217;s Station, was fought on March 5, 1863, near the present-day town of the same<br \/>\nname.<\/p>\n<h2>Getting There<\/h2>\n<p>Interstate 65 runs north-south through Franklin, Brentwood and Thompson&#8217;s Station.<br \/>\nInterstate 840 crosses the county&#8217;s southern half, and U.S. 31, U.S. 431 and State Route 96<br \/>\nserve the rest of the county.<\/p>\n<ul>\n<li>Nashville &mdash; about 21 miles north<\/li>\n<li>Murfreesboro &mdash; about 25 miles east<\/li>\n<li>Columbia &mdash; about 20 miles southwest<\/li>\n<li>Lewisburg &mdash; about 25 miles south<\/li>\n<\/ul>\n<p>Nashville International Airport, roughly 25 miles northeast of Franklin, is the nearest major<br \/>\ncommercial airport.
