State report · National rank #2 of 50
South Dakota
South Dakota is excellent zombie-survival territory for prepared rural communities. It has fewer than a million residents, tens of millions of farm acres, millions of cattle, wind energy, open space, and defensible terrain in the Black Hills and Badlands. The catch is extreme winter weather, drought, prairie fire, long distances, sparse medical services, and limited freshwater in some areas. The zombies are manageable; climate and logistics are the real test.

South Dakota scored three times
A state that handles shamblers can get erased by sprinters. Here is how South Dakota performs under each outbreak model.
Slow zombies reward distance, terrain, food and freshwater. South Dakota has about 935,094 people spread across 42.2 million acres of farm operations, with 3.55 million cattle and calves. 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. South Dakota wins on very low population, excellent route redundancy and no giant metro to funnel people into. The weakness is what happens after you escape — weather and distance to medicine.
Yes, we know they're not technically zombies. This asks whether a settlement still works once supply chains stop. The food depth here is close to unmatched; the limits are climate and how far advanced care sits from a rural community.
What helps
- Black Hills, prairie, river valleys, badlands and enormous low-density agricultural country
- Missouri River reservoirs, groundwater, prairie lakes and local river systems
- 42.2 million acres in farm operations
- 3.55 million cattle and calves
- 2.19 million hogs, more than 1.08 billion bushels of corn and about 238 million bushels of soybeans in 2025
- Strong wind resources plus hydroelectricity, natural gas and other regional generation
- Ellsworth Air Force Base, the South Dakota National Guard and regional federal assets
What hurts
- Blizzards, extreme cold, tornadoes, severe thunderstorms, drought, wildfire and flooding
- Remote safety can mean thinner medicine and longer repair distances
- Main corridors become population funnels after a late evacuation
- The western half can turn dry quickly

South Dakota's zombie superpowers
Black Hills, prairie, river valleys, badlands and enormous low-density agricultural country determine movement, observation, evacuation and settlement options. The best refuge needs terrain plus water plus food plus energy plus access.
1 · Population-to-food ratio
Under one million people share 42.2 million farm acres and more than 3.5 million cattle. The arithmetic is absurd.
2 · Winter suppression
South Dakota's cold is a major defensive factor, and it arrives every single year.
3 · The Black Hills
The state has considerably more defensive terrain than its prairie reputation suggests.
4 · Wind and agriculture
Distributed wind plus enormous food depth make long-term settlement unusually plausible.
The catch
Weather, distance and drought
Winter
The weather will happily kill the survivors too. It does not distinguish.
Medical distance
Advanced care can be hours away across roads that close in a blizzard.
Drought and wildfire
The western half can turn dry quickly, and cattle country still needs water.
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
Black Hills fringe
Terrain, water and communities with real winter infrastructure create the strongest balance in the state.
- Defensive terrain without total isolation
- Established towns with heat and fuel
- Dependable water rather than seasonal flow
- Hunting and timber close at hand
Central Missouri River agricultural communities
Food, water and route redundancy are all excellent along the river corridor.
Eastern rural farm country away from Sioux Falls
Extreme food depth and low density, though the terrain is flatter and more exposed.
Where not to be
Remote site with no heat or fuel redundancy
Winter is the real predator here, and it does not need to find you — you are standing in it.
Sioux Falls
Still small by national standards, but it is the state's main population centre.
Dry western site without a secure water plan
Cattle country still needs water, and so do you.

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.
