State report · National rank #21 of 50
Tennessee
Tennessee has a strong mix of food, water, terrain, and transportation resources. It offers farms, livestock, forests, major rivers, reservoirs, Appalachian mountains, caves, and many defensible rural communities. The catch is population pressure around Nashville, Memphis, Knoxville, and Chattanooga, plus dangerous interstate corridors, tornadoes, floods, heat, and severe storms. Eastern Tennessee offers excellent refuge terrain, but reaching it before the roads lock up would matter.

Tennessee scored three times
A state that handles shamblers can get erased by sprinters. Here is how Tennessee performs under each outbreak model.
Slow zombies reward distance, terrain, food and freshwater. Tennessee has about 7,315,076 people and 10.7 million acres in farm operations, plus 1.56 million cattle and calves, 140.13 million bushels of corn and 63.84 million bushels of soybeans. Against walkers there is time to turn all of that into a defensible long-term system.
Fast zombies turn evacuation into a race against the road network, and Tennessee's problem is arithmetic: four significant metros rather than one. Nashville, Memphis, Knoxville and Chattanooga spread first-wave pressure across the whole state instead of concentrating it somewhere avoidable.
Yes, we know they're not technically zombies. This asks whether a settlement can still work after modern supply chains stop, and Tennessee does well: rugged eastern terrain, elite freshwater, real agricultural depth and a Tennessee Valley power system built around hydro and nuclear.
What helps
- Appalachian mountains, Cumberland Plateau, forested ridges, river valleys and broad agricultural areas
- Tennessee, Cumberland and Mississippi river systems, reservoirs, springs, groundwater and high rainfall
- 10.7 million acres in farm operations
- 1.56 million cattle and calves
- 63.84 million bushels of soybeans, 140.13 million bushels of corn, 19.61 million bushels of wheat and 3.615 million tons of hay in 2025
- A large Tennessee Valley power system with nuclear, hydroelectric, natural gas and other generation
- Arnold Air Force Base, Naval Support Activity Mid-South, the Tennessee National Guard and major Tennessee Valley federal infrastructure
What hurts
- Four growing metros spreading first-wave pressure statewide
- Tornadoes, severe thunderstorms, flooding, heat, winter storms and localised wildfire
- Remote safety can mean thinner medicine and longer repair distances
- Main corridors become population funnels after a late evacuation

Tennessee's zombie superpowers
Appalachian mountains, Cumberland Plateau, forested ridges, river valleys and broad agricultural areas determine movement, observation, evacuation and settlement options. The best refuge needs terrain plus water plus food plus energy plus access.
1 · Terrain and water together
Tennessee gets both rugged eastern terrain and major river and reservoir systems, which is a genuinely powerful combination.
2 · Agricultural depth
USDA lists 10.7 million farm acres, 1.56 million cattle and large corn, soybean, wheat and hay production.
3 · Forests
Timber, fuelwood, game habitat and concealment improve long-collapse resilience considerably.
4 · TVA infrastructure
The Tennessee Valley's power and water-management systems give the state major organised-response depth.
The catch
Four metros, and the weather between them
Metro growth
Nashville and other growing urban corridors create more first-wave population pressure than the state's rural image suggests.
Severe weather
Tornadoes and flooding remain major infrastructure risks year after year.
River crossings
Water helps defence but concentrates movement onto bridges when everyone needs them at once.
The framework
25 survival factors, scored 1–10
Every state is measured on the same 25 factors. Weighting shifts by scenario — terrain matters more against sprinters, agriculture matters more in a long collapse.
Tactics
What works, by scenario
| Strategy | Walking Dead | World War Z | Last of Us |
|---|---|---|---|
| Rural farm or ranch with independent water | Excellent | Very good if reached early | Excellent |
| Small agricultural town | Very good | Good | Excellent |
| Remote site with no food system | Good early | Very good for isolation | Poor long-term |
| Major highway evacuation | Good early, bad late | Terrible late | Poor after collapse |
| Major metro shelter | Poor | Terrible | Poor |
| Distributed renewable power | Very good | Good | Excellent |
| Hunting and fishing supplement | Very good | Good | Very good |
| One-road refuge | Risky | Risky | Risky |
Geography
Where to be
Cumberland Plateau / eastern rural Tennessee
Water, terrain, farms and forests create the strongest balance in the state.
- Plateau edges and ridges for cover
- Springs and reservoirs nearby
- Working farms within reach
- Clear of all four metros
Rural northeast Tennessee
Appalachian terrain and water with genuinely small communities.
South-central farm country away from Nashville
Excellent food and water, though weaker terrain than the east.
Where not to be
Nashville metro
Rapid growth and interstate concentration make it a major first-wave problem.
Memphis corridor
Regional movement and Mississippi River crossings create chokepoints.
Low floodplain refuge
A river barrier is useful until the river moves.

Where the numbers come from
The Zombie Survival Index is a fictional entertainment ranking that uses real public data as its inputs. Every state is scored on the same 25 factors under three outbreak models, and the overall number blends those results. All fifty states have been assessed and normalised against the same national scoring set.
