The three tests

Montana scored three times

A state that handles shamblers can get erased by sprinters. Here is how Montana performs under each outbreak model.

Walking DeadThe Walking Dead

96

Slow zombies reward distance, terrain, food and freshwater. Montana has about 1.14 million people and 57.3 million acres in farm operations, with 2.14 million cattle and calves. Walkers turn the apocalypse into a long endurance problem rather than a speed contest, and endurance is what Montana sells.

World War ZWorld War Z

92

Fast zombies make timing more important than raw resources. A state can have food, water and land and still lose the first day because the road network stops moving. Montana survives that test on sheer emptiness — there is very little population to jam the roads in the first place.

Last of UsThe Last of Us

82

Yes, we know they're not technically zombies. This tests whether a settlement can function for years. Montana has the food, water, timber and wildlife; the question is whether you can solve winter without the modern repair network behind you.

What helps

Rocky Mountains, high plains, river valleys, forests and enormous sparsely populated distances
Missouri, Yellowstone, Clark Fork and Columbia headwaters, mountain snowpack, reservoirs and groundwater
57.3 million acres in farm operations
2.14 million cattle and calves
Major wheat, barley, lentil, pea, chickpea, hay and cattle production
A resource-rich system with hydroelectricity, coal, wind, natural gas and petroleum production
Malmstrom Air Force Base, the Montana National Guard and strategic missile infrastructure

What hurts

Extreme winter cold, blizzards, wildfire, drought, flooding and severe storms
Remote safety can mean thinner medicine and longer repair distances
Major corridors can become population funnels if evacuation begins late
Medicine, parts and specialised labour may be hundreds of miles away

Choose an agricultural valley or small town with dependable water, winter heat and fuel. Then let distance and terrain do the rest.

The reason for the score

Montana's zombie superpowers

Rocky Mountains, high plains, river valleys, forests and enormous sparsely populated distances define how infected move, which routes fail first and where durable communities can exist. The best refuge is where terrain, food, water, energy and access overlap.

1 · Population-to-resource ratio

Barely 1.14 million people share 57.3 million farm acres and more than two million cattle.

2 · Mountains and distance

Montana has both terrain and space, which is a genuinely rare combination.

3 · Food

Wheat, barley, lentils, peas, chickpeas, hay and cattle provide excellent long-term food depth.

4 · Winter suppression

Cold is severe enough to become a major seasonal obstacle to infected movement.

The catch

Winter, logistics and drought

Winter

The same cold that helps you can end you quickly without heat and fuel.

Long logistics

Medicine, parts and specialised labour may be hundreds of miles away.

Wildfire and drought

A mountain or forest refuge still has to survive dry years, and Montana's size does not manufacture 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.

01 Population density Extremely low density 10/10

02 Major city exposure No major metro exposure 10/10

03 Road escape capacity Road network is sparse but generally uncongested 7/10

04 Freshwater availability Strong rivers and snowpack, locally dry areas 8/10

05 Agricultural capacity 57.3 million farm acres 10/10

06 Food self-sufficiency Massive cattle and grain production 9/10

07 Wilderness & remote land Exceptional remote land 10/10

08 Natural defensive terrain Mountains and valleys are elite terrain 10/10

09 Climate survivability Winter is demanding 5/10

10 Winter zombie suppression Elite winter suppression 10/10

11 Natural disaster risk Wildfire, drought and blizzard risk 5/10

12 Energy production Strong hydro, coal and wind resource base 8/10

13 Off-grid energy potential Excellent wind, hydro and solar potential 10/10

14 Medical resources Advanced medicine is sparse outside cities 5/10

15 Military & Guard presence Malmstrom and Guard assets 7/10

16 Emergency management Strong wildfire and winter response capability 8/10

17 Supply & logistics Long logistics distances are a weakness 5/10

18 Infrastructure vulnerability Remote infrastructure and winter access are fragile 6/10

19 Survival resource availability Food, water, wildlife, timber and energy are strong 10/10

20 Evacuation & refuge potential Elite refuge potential 10/10

21 Natural barriers & water access Mountains and rivers create major barriers 9/10

22 Distance from population centers Huge distances from population centers 10/10

23 Chokepoint & bridge dependency Some passes and river crossings can choke 8/10

24 Hunting, fishing & foraging Elite hunting and fishing 10/10

25 Long-term settlement potential Very strong with winter and logistics planning 8/10

Geography

Where to be

Best overall

Western or central agricultural valleys

Water, farms, small towns and terrain create the best balance anywhere in the state.

Dependable river or snowpack-fed water
Working farmland with outbuildings
Mountain barriers limiting approaches
A small town close enough for heat and fuel

Runner-up

Missouri River headwaters communities

Water and agricultural access with strong separation from anything resembling a crowd.

Third

Eastern ranch country near dependable water

Extreme space and food, but less terrain and considerably longer logistics.

Where not to be

Avoid

Remote mountain cabin with no winter road access

The zombies may never arrive. Neither will the fuel truck.

Avoid early

Billings or Missoula core

Small by national standards, but still the local concentration of people.

Avoid

Dry ranch site without redundant water

Montana's size does not manufacture water. Verify the well before you commit.

Verdict

90 out of 100 · Grade A− · Rank #4

Montana is among the best zombie-survival states for groups prepared for distance and winter. It has barely more than a million residents, enormous ranches and grain production, mountains, forests, rivers, hunting, energy resources, and vast open territory. The catch is extreme cold, wildfire, drought, long travel distances, limited medical access, and dependence on fuel and machinery. A remote refuge is valuable only if it can remain supplied and self-sufficient.

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.
