About Sumner County

Located just outside of Nashville, Sumner County is its own unique destination.

Sumner County is located on the central northern border of Tennessee, in what is called Middle Tennessee. As of the 2020 census, the population was 200,557 people with a median age of 39.6 and a median household income of $69,878. Between 2019 and 2020 the population of Sumner County, TN grew from 183,437 to 187,680, a 2.31% increase and its median household income grew from $67,204 to $69,878, a 3.98% increase. Its county seat is Gallatin, and its largest city is Hendersonville. The county is named for American Revolutionary War hero General Jethro Sumner.

Sumner County is part of the Nashville-Davidson–Murfreesboro–Franklin, TN Metropolitan Statistical Area. The county is made up of seven cities, including Gallatin, Goodlettsville, Hendersonville, Millersville, Portland, Westmoreland, and White House. Sumner County is 25 miles northeast of Nashville, Tennessee.


Prior to the European colonization of North America, the county had been inhabited by various cultures of Native Americans for several thousand years. Nomadic Paleo and Archaic hunter-gatherer campsites, as well as substantial Woodland and Mississippian-period occupation sites and burial grounds, can be found scattered throughout the county, particularly along the waterways. The majority of these sites exist along natural waterways, with the highest concentration occurring along what is now known as the Cumberland River. Mississippian period earthwork mounds can still be seen in Hendersonville, and most notably, at Castalian Springs. Long before Europeans entered the area, Native Americans made use of the natural hot springs for their medicinal and healing properties.

British colonial longhunters traveled into the area as early as the 1760s, following existing Indian and buffalo trails. By the early 1780s, they had erected several trading posts in the region. The most prominent was Mansker’s Station, which was built by Kasper Mansker near a salt lick (where modern Goodlettsville would develop). Another was Bledsoe’s Station, built by Isaac Bledsoe at Castilian Springs. Sumner County was organized in 1786, just 3 years after the end of the American Revolutionary War, when Tennessee was still the western part of North Carolina.

The county was developed for agriculture: tobacco and hemp, and blooded livestock. Numerous settlers came from central Kentucky’s Bluegrass Region, where these were the most important products. Middle Tennessee had fertile lands that could be used for similar crops and supported high-quality livestock as well. The larger planters depended on the labor of enslaved African Americans, but Middle Tennessee had a lower proportion of slaves in the population than in West Tennessee, the plantation area of Memphis and the Delta, where cotton was cultivated.

During the American Civil War, most of Tennessee was occupied by Union troops from 1862. This led to a breakdown in civil order in many areas. The Union commander, Eleazer A. Paine, was based at Gallatin, the county seat. He was notoriously cruel and had suspected spies publicly executed without trial in the town square. He was eventually replaced because of his mistreatment of the people.

In 1873 the county was hit hard by the fourth cholera pandemic of the century, which had begun about 1863 in Asia. It eventually reached North America and was spread by steamboat passengers who traveled throughout the waterways, especially in the South on the Mississippi River and its tributaries. An estimated 120 persons died of cholera in Sumner County in 1873, mostly during the summer. The disease was spread mainly through contaminated water, due to the lack of sanitation. About four-fifths of the county’s victims were African Americans. Many families, both black and white, lost multiple members. In the United States overall, about 50,000 persons died of cholera in the 1870s.


As of the census of 2010, there were 160,645 people, 60,975 households, and 44,593 families living in the county. The population density was 303.68 persons per square mile.
