Fort Campbell Shapes One of America's Youngest Counties

Written by Adelle Wood | Apr 21, 2026 11:02:41 AM

13.0% of adult residents of Montgomery County, Tennessee are military veterans, the highest share of any large county in Tennessee and more than 2.3 times the national median of 5.7%. Yet only 9.8% of the population is 65 or older, roughly half the national median of 19.0%. That combination, lots of veterans and very few retirees, is nearly impossible to find anywhere else in the country and it is driven almost entirely by one installation.

The Fort Campbell Effect

Montgomery County, Tennessee is the civilian face of Fort Campbell, home of the 101st Airborne Division. Clarksville, the county seat, sits on the Kentucky border and functions as the civilian half of the Fort Campbell economy. With a population of 227,957, the county is one of the largest in the United States with a double-digit veteran share, and its demographics reflect a constant rotation of active-duty soldiers, spouses, and recently separated service members who stay in the area rather than leaving.

A County That Skews Young

Active-duty bases pull in soldiers in their twenties and thirties, along with their families, and the Montgomery County age pyramid shows it clearly. 26.9% of residents are under 18, above the national median of 21.9%. The county's civilian labor force participation rate sits at 59.5%, and female labor force participation is 56.9%, both well above the figures in traditional retiree-heavy veteran counties like those in Florida's Panhandle.

Social Characteristics: Mobility, Language, and Origin

Military life means churn. 81.1% of Montgomery County residents lived in the same home a year earlier, below the national median of 88.8%. 6.5% of residents are foreign born, above the national median of 3.1%, and 9.8% of households speak a language other than English at home. Part of that reflects military marriages formed during overseas deployments, part reflects the broader Nashville metro spillover into northern Middle Tennessee.

Income, Housing, and Cost of Living

Median household income in the county is $72,365, above the national median of $64,391 and above the Tennessee county median of $58,103. The poverty rate is 11.6%, lower than the national median of 13.6%.

Home prices are close to national norms. The median value of an owner-occupied home is $248,300, above the national median of $186,300, and 62.9% of housing units are owner-occupied. Renters pay a median gross rent of $1,219, compared with a national median of $884. Monthly mortgage costs average $1,543.

Education, Health, and Connectivity

31.7% of adults in Montgomery County hold a bachelor's degree or higher, above the national median of 22.3%, and 94.3% have completed high school. The under-65 disability rate is 11.9%, close to the national median of 11.1%, and 9.9% of residents under 65 are uninsured. Broadband reaches 92.6% of households, above the national median of 86.0%.

Tennessee's Top Veteran Counties

  4. Henry County, Tennessee, 8.0% veterans

The Top Ten Nationally

Among US counties with more than 10,000 residents, these have the highest veteran shares. Montgomery County, Tennessee ranks #9, and it is the only county in the top ten with a 65-and-over share below 19%.

  1. Okaloosa County, Florida, 14.7% veterans
  2. Lampasas County, Texas, 14.7% veterans
  3. Teller County, Colorado, 14.4% veterans
  4. Cochise County, Arizona, 13.8% veterans
  5. Nye County, Nevada, 13.6% veterans
  6. Elmore County, Idaho, 13.5% veterans
  7. La Paz County, Arizona, 13.5% veterans
  8. Sumter County, Florida, 13.2% veterans
  9. Montgomery County, Tennessee, 13.0% veterans
  10. Bell County, Texas, 13.0% veterans

Why the Pattern Matters

Most of the counties with the highest veteran shares are retiree magnets. A handful, like Montgomery County, are active-duty towns, and they look demographically different in almost every way. They have more children in schools, higher birth rates, more renters, more churn in real estate, and larger demand for working-age support services rather than senior services. When people talk about "veteran counties," it helps to know which kind they mean.
