State report · National rank #18 of 50
Iowa
Iowa is one of America's strongest food-based zombie survival states. It has enormous corn and soybean production, millions of hogs and cattle, productive soil, groundwater, wind power, extensive rural roads, and relatively modest population pressure outside a few cities. The catch is terrain: much of the state is open and difficult to defend, while tornadoes, floods, harsh winters, agricultural dependence on fuel and machinery, and limited natural barriers could expose otherwise well-supplied communities.

Iowa scored three times
A state that handles shamblers can get erased by sprinters. Here is how Iowa performs under each outbreak model.
Slow zombies reward distance, local food, water, defensive terrain and the luxury of time. Iowa begins with about 3,238,387 people, but its real advantage is the resource-to-population ratio once you leave the main cities. USDA lists 29.9 million acres across 86,200 farm operations, with 3.45 million cattle and 25.2 million hogs.
Fast zombies turn transportation into a timing problem. A six-lane highway is useful right up until six lanes stop moving. Iowa's county-road grid is a genuine asset here, but open terrain means that once survivors arrive there is very little to put between themselves and what is coming.
Yes, we know they're not technically zombies. This is about keeping a settlement alive for years rather than surviving one bad afternoon. Iowa's numbers are not stored food — they are a functioning food-production base, which is exactly what a decade-long collapse rewards.
What helps
- Mostly open agricultural plains, with river valleys, wooded areas and rugged Driftless terrain in the northeast
- Mississippi and Missouri rivers, interior rivers, groundwater and farm wells
- 29.9 million acres in farm operations across 86,200 farms
- 3.45 million cattle and calves
- 25.2 million hogs, 10.8 million turkeys, 6.053 billion pounds of milk, 2.772 billion bushels of corn and 595.63 million bushels of soybeans in 2025
- 23,226 MW of net summer capacity in 2024 with exceptionally strong wind generation
- The Iowa National Guard, Camp Dodge and regional military facilities
What hurts
- Open terrain with limited natural defensive geography
- Tornadoes, severe thunderstorms, derechos, flooding, blizzards, extreme heat and cold
- Rural isolation can trade safety for thinner medical and repair capacity
- Major transport corridors become liabilities when everyone moves at once

Iowa's zombie superpowers
Mostly open agricultural plains, with river valleys, wooded areas and rugged Driftless terrain in the northeast, define how infected move, where people can hide, and which roads become mandatory. The best refuge is not simply the remotest place — it is where terrain plus water plus food plus energy plus access overlap.
1 · Food surplus
Iowa's numbers are absurd: 29.9 million farm acres, 25.2 million hogs, 3.45 million cattle and nearly 2.8 billion bushels of corn.
2 · Low population pressure
Only about 3.24 million people share that entire agricultural base.
3 · Wind energy
Iowa's wind resource is one of the strongest distributed-energy advantages in the Midwest.
4 · Road grid
County roads provide exceptional route redundancy compared with mountain or coastal states.
The catch
Open ground, hostile sky
Open terrain
You can see trouble coming. Trouble can also see you.
Severe weather
Tornadoes, derechos, blizzards and floods are legitimate infrastructure killers.
Little wilderness
Iowa is rural, not remote. Farm country is still inhabited and still roaded.
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
Northeast Iowa / Driftless fringe
More terrain and forest without giving up farm and water access.
- Rugged ground in an otherwise flat state
- Working farms and wells nearby
- River access without metro exposure
- Wooded cover for movement
Rural north-central Iowa
Extreme food depth and low density.
Western Iowa farm communities away from Omaha and Sioux City
Strong agriculture and roads, but open terrain.
Where not to be
Des Moines metro
Largest population concentration and major interstate junction.
Flood-prone river bottoms
Great soil is not worth sleeping underwater.
Unprotected farmstead with no storm shelter
In Iowa the sky is a recurring adversary.

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.
