The three tests

Arizona scored three times

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

Walking DeadThe Walking Dead

79

Slow zombies reward time, distance, terrain and food. Arizona starts with about 7.62 million people, but its survival value depends less on the statewide number than on where those people are concentrated and how quickly survivors can separate themselves from the main corridors.

World War ZWorld War Z

76

Fast zombies change the math, and Arizona holds up unusually well — 76 is a strong score this far down the rankings. Enormous remote country, elite terrain and good route redundancy mean outbreak pressure drops away sharply once you clear the Phoenix basin.

Last of UsThe Last of Us

64

Yes, we know they're not technically zombies. This is a settlement problem rather than an evacuation problem, and it is where Arizona falls hard. Water scarcity is the state's defining constraint, and no amount of terrain or sunshine substitutes for it.

What helps

High desert, mountain ranges, canyons and enormous open country
Colorado River supplies, reservoirs and groundwater systems are critical, but long-term scarcity is the state's defining constraint
24.9 million acres in farm operations across 15,100 farms
About 870,000 cattle and calves
Strong dairy, lettuce, hay, vegetable and livestock production concentrated where irrigation works, plus major alfalfa, wheat, cotton and pecan output
A large electric-generation system, major solar potential and substantial natural-gas and nuclear generation
Luke Air Force Base, Davis-Monthan Air Force Base, Fort Huachuca, Marine Corps Air Station Yuma and Arizona National Guard forces

What hurts

Water scarcity as the state's defining long-term constraint
Extreme heat, drought, wildfire, flash flooding and dust storms
Major highways can reverse from escape routes into population funnels
Rural refuge quality varies enormously by water, road redundancy and medical access

Leave the Phoenix basin early and move toward higher-elevation communities where water is proven, temperatures are survivable and roads do not all funnel through one metro corridor.

The reason for the score

Arizona's zombie superpowers

High desert, mountain ranges, canyons and enormous open country are not background scenery in this model. They determine how many directions infected can approach from, how quickly humans can leave population centres, whether a refuge has water, and whether roads remain optional or become chokepoints.

1 · Terrain everywhere

Arizona is not a flat desert. Mountain ranges, canyon country, plateaus and broken terrain create excellent movement control and observation — a perfect 10.

2 · Solar is ridiculous

A long-term settlement with panels, batteries and the knowledge to maintain them starts with one of the best solar resources in the country.

3 · Agriculture beats the desert stereotype

USDA lists 24.9 million acres in farm operations, about 870,000 cattle, and very large dairy and irrigated vegetable production. Arizona can grow food — where water exists.

4 · High-country refuges

Northern and eastern high-elevation communities trade Phoenix heat for forests, colder winters and more defensible ground.

The catch

Water is the boss fight

Arizona's own water department operates 100-year assured-supply programmes because groundwater depletion and long-term supply are real constraints. In a collapse, every settlement has to solve this locally.

Phoenix is enormous and hot

The Phoenix metro combines population concentration, freeway dependence and extreme summer heat. Losing power there is not a minor inconvenience.

Wildfire follows you uphill

The same forested high country that improves terrain and climate can carry severe wildfire risk.

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 Large state with moderate overall density 9/10

02 Major city exposure Phoenix creates a major concentration; Tucson is secondary 5/10

03 Road escape capacity Strong highway network and many rural routes, though Phoenix can jam 8/10

04 Freshwater availability Colorado River, reservoirs and groundwater exist but scarcity is fundamental 4/10

05 Agricultural capacity Large farm and ranch acreage with highly productive irrigated zones 7/10

06 Food self-sufficiency Strong dairy, vegetables and livestock but dependent on water systems 7/10

07 Wilderness & remote land Enormous remote desert and mountain territory 10/10

08 Natural defensive terrain Mountains, canyons and plateaus are excellent defensive terrain 10/10

09 Climate survivability Heat is a major human-survival penalty 5/10

10 Winter zombie suppression Higher elevations get useful cold; low desert does not 6/10

11 Natural disaster risk Drought, wildfire, extreme heat, flash flood and dust-storm risks 4/10

12 Energy production Large diversified electric system 9/10

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

14 Medical resources Strong major-city medicine but rural distances matter 9/10

15 Military & Guard presence Several major military installations 9/10

16 Emergency management Experienced wildfire and all-hazards response capability 9/10

17 Supply & logistics Major interstate, rail and air logistics 9/10

18 Infrastructure vulnerability Water and grid dependence are critical vulnerabilities 6/10

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

20 Evacuation & refuge potential Huge refuge potential away from metros if water is solved 9/10

21 Natural barriers & water access Canyons, rivers and mountains create barriers, but surface water is sparse 7/10

22 Distance from population centers Much of rural Arizona is far from giant population centers 9/10

23 Chokepoint & bridge dependency Route redundancy is good, though mountain and desert corridors can narrow 8/10

24 Hunting, fishing & foraging Good big-game and desert and mountain hunting; fishing is more limited 8/10

25 Long-term settlement potential Strong only where water and heat management are sustainable 7/10

Geography

Where to be

Best overall

High-country communities outside Phoenix

Elevation, forest, cooler weather and defensive terrain — but only where water supply is established.

Verify the water first, always
Elevation out of the heat
Forest cover and real terrain
Not dependent on the Phoenix corridor

Runner-up

Rim Country / Mogollon Plateau communities

Strong terrain, forest and climate advantages with access to smaller towns.

Third

Southeastern mountain valleys

Agriculture, ranching and defensible mountain geography can work well if groundwater is sustainable.

Where not to be

Avoid early

Phoenix metro

Huge population concentration, heat and freeway dependence create a brutal first-wave environment.

Avoid

Low desert without a proven water source

Shade is not a water plan.

Avoid

Wildland-urban interface with one road out

Wildfire plus evacuation plus infected is a terrible three-way problem.

Verdict

73 out of 100 · Grade C · Rank #38

Arizona offers excellent zombie defense but unforgiving long-term logistics. Its mountains, canyons, high desert, solar potential, open space, and large areas of federal land provide isolation, visibility, and multiple refuge options away from Phoenix and Tucson. The catch is water: extreme heat, drought, wildfire, limited farmland, and dependence on reservoirs, canals, pumps, and imported supplies mean one infrastructure failure could become more dangerous than the zombies.

Leave the Phoenix basin early and move toward higher-elevation communities where water is proven, temperatures are survivable and roads do not all funnel through one metro corridor.

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.
