The three tests

Utah scored three times

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

Walking DeadThe Walking Dead

Slow zombies reward distance, terrain, food and freshwater. Utah has about 3,538,904 people and 10.5 million acres in farm operations, plus 760,000 cattle and calves and 2.255 billion pounds of milk. Against walkers, survivors have time to turn those resources into a defensible long-term system — provided the water holds.

Fast zombies turn evacuation into a race against the road network. Utah scores unusually well here: outside the Wasatch Front there is very little population and the terrain is punishing. The catch is that nearly everyone lives along one north-south corridor, and that corridor is the failure mode.

Last of UsThe Last of Us

78

Yes, we know they're not technically zombies. This asks whether a settlement can still work after modern supply chains stop. Utah has terrain, ranching and the best solar in the batch. Long-term scarcity of water is the ceiling, and it is not a problem you can improvise around.

What helps

Wasatch Range, high plateaus, canyons, deserts, mountain valleys and vast federal land
Mountain snowpack, reservoirs, groundwater and river systems
10.5 million acres in farm operations
760,000 cattle and calves
2.255 billion pounds of milk, 2.54 million tons of hay, about 5.0 million bushels of wheat and 32.2 million pounds of tart cherries in 2025
Major coal and natural-gas resources with exceptional solar potential and growing wind and geothermal options
Hill Air Force Base, Dugway Proving Ground, the Utah Test and Training Range and Utah National Guard forces

What hurts

Long-term water scarcity as a central statewide constraint
Drought, wildfire, extreme heat, winter storms, flash flooding and earthquake risk along the Wasatch Front
Remote safety can mean thinner medicine and longer repair distances
Main corridors become population funnels after a late evacuation

Get away from the Wasatch Front before the corridor jams, then favour a central or mountain-valley community with proven water, agriculture, winter heat and solar potential.

The reason for the score

Utah's zombie superpowers

Wasatch Range, high plateaus, canyons, deserts, mountain valleys and vast federal land determine movement, observation, evacuation and settlement options. The best refuge needs terrain plus water plus food plus energy plus access — and in Utah the water term is the one that binds.

1 · Mountains and canyons

Utah's terrain channels movement and isolates valleys about as well as any state in the country.

2 · Solar

Few states have better distributed-solar potential, which matters enormously once centralised power stops.

3 · Ranching and dairy

USDA lists 760,000 cattle and more than 2.25 billion pounds of milk in 2025.

4 · Empty space

Outside the Wasatch Front, Utah has enormous low-density territory with almost nobody in it.

The catch

Water, and one very long corridor

Water

Utah's long-term settlement ceiling is set by reliable water, not by terrain or food.

The Wasatch Front

Most residents are concentrated in one long urban corridor with one dominant escape route.

Earthquake and wildfire risk

The best mountain terrain carries its own infrastructure hazards.

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 Low statewide density 9/10

02 Major city exposure Wasatch Front concentrates most residents 5/10

03 Road escape capacity Good highways, but the north-south corridor is a major vulnerability 8/10

04 Freshwater availability Snowpack and reservoirs help, but scarcity is fundamental 5/10

05 Agricultural capacity 10.5 million farm acres 8/10

06 Food self-sufficiency Strong cattle, dairy and hay; limited crop diversity 8/10

07 Wilderness & remote land Exceptional remote public land 10/10

08 Natural defensive terrain Mountain and canyon terrain is elite 10/10

09 Climate survivability Generally survivable outside low desert extremes 7/10

10 Winter zombie suppression Strong mountain winter suppression 8/10

11 Natural disaster risk Drought, wildfire, heat and earthquake risk 5/10

12 Energy production Strong regional energy resources 9/10

13 Off-grid energy potential Elite solar potential 10/10

14 Medical resources Good urban medicine, thinner rural access 8/10

15 Military & Guard presence Major Air Force and testing assets 9/10

16 Emergency management Strong wildfire and earthquake preparedness 9/10

17 Supply & logistics Good regional logistics 8/10

18 Infrastructure vulnerability Water and Wasatch corridor dependencies matter 6/10

19 Survival resource availability Livestock, solar, minerals and local agriculture are useful 8/10

20 Evacuation & refuge potential Elite refuge potential if water is solved 10/10

21 Natural barriers & water access Mountains and canyons create major barriers 8/10

22 Distance from population centers Large areas far from population centers 10/10

23 Chokepoint & bridge dependency Some canyon, pass and Wasatch corridor chokepoints 8/10

24 Hunting, fishing & foraging Good hunting and fishing in mountain areas 8/10

25 Long-term settlement potential Strong where water is sustainable 8/10

Geography

Where to be

Best overall

Central Utah mountain valleys

Terrain, farms, small communities and separation are excellent if water is proven.

Mountain barriers on more than one side
Established irrigation and grazing
Exceptional solar potential
Well clear of the Wasatch Front

Runner-up

Rural Cache and Wasatch backcountry fringe

Water and agriculture are strong, but stay off the main population corridor.

Third

South-central high valleys

Isolation and solar are strong; water and logistics must be verified first.

Where not to be

Avoid early

Salt Lake–Provo Wasatch Front

Population concentration plus one dominant corridor is the whole problem.

Avoid

Desert refuge without a verified water source

The view is not potable.

Avoid

One-canyon access settlement

A single blocked canyon road can erase the plan.

Verdict

86 out of 100 · Grade B · Rank #12

Utah offers outstanding defensive terrain and a relatively manageable population. Its mountains, desert, cattle, solar potential, mineral and energy resources, and vast public lands provide isolation and multiple refuge options away from the Wasatch Front. The catch is water: drought, limited farmland, wildfire, extreme temperatures, and heavy population concentration along one narrow urban corridor create serious vulnerability. Survivors can find defensible ground, but reliable water determines whether they can stay.

Walking Dead 92. World War Z 88. Last of Us 78.

Get away from the Wasatch Front before the corridor jams, then favour a central or mountain-valley community with proven water, agriculture, winter heat and solar potential.

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.
