Population density is population divided by area of state (square miles). High population density means more zombies, so this is a negative factor. Decrease the weight if you believe population density should be less of a negative factor.

Air travel destination

The number of passengers delivered to a state increases the probability of transmission. This is a negative factor, so adjust the weight down to reduce its impact.

Though body shots (not that kind) are harmless to zombies, they are easily dispatched by any head wound, regardless of caliber. The formula here is straightforward, more guns equal reduced zombie loitering. States with more firearms per capita have higher survivability.


Source: Neighbor state population
Understanding isolation is easy. If you are all alone on an island and you are not a zombie already – relax. States with crowded neighbors are disadvantaged. This factor combines the population density of neighbor states and is a negative factor, so decrease the weight if you don’t think this is as important.

Your turn

When the original zombie survivability metrics were published it was a true demonstration of collective analysis. People just like you reviewed the metrics and source data and provided enlightening observations.

This new map allows you to present your survivability projections and help millions of people prepare.


  1. Experiment by adjusting the weights for each attribute of the formula.

  2. and adjust weights as desired.

8, 2, 10, 4 Default Tom Deaderick

Population density is important, neighboring state population is half as important (hopefully someone else will eliminate zombies before they migrate to your state) and firearms are highest importance.


4, 1, 8, 10 Isolation is the best protection Isolationist

Fewer zombies = less problems, less ammo expenditure, etc. Alaska has to be safer than a state like Wyoming. This model seems more realistic.


7, 2, 10, 3 Utah - Exception to Population Density/Isolation issues Paul M

Utah is extremely community oriented. When they hosted the 2002 Winter Olympic Games they set records for the number of volunteers, making it the first Winter Games in history to turn a profit. No Winter Games before that had even managed to break even. My theory is that this sense of community and putting others before yourself would cause tight groups to form, sharing resources, securing safe zones and fighting together to repel and eventually diminish the zombie hordes. While I dont think this makes Utah the number 1 state, I do think it should move it up a notch or two.
