I think their 90% guess is far too high. Sure there are some segments of the population that might fall prey at the 90% rate. Other segments would be nearly impossible for a zombie to get to. Overall I’d guess the average rate would be more like 20% to 40%, with that number tailing off significantly as the zombies transitioned to dead and the entire population density went down.
The speed at which zombies move would largely impact our survival rate, possibly more so than any other factor. Make it to round 53 in Nazi zombies and tell me I’m wrong lol! If they can spend money researching a fictional creature, I can use the same fiction to come to my own conclusion on the fictional subject.
I remember a short zombie story set in the older inner city, maybe Chicago or Philadelphia.
A white guy from the suburbs with the new government was doing a census and surprised at the 40% survival rate, officially 20% because half the people left but never came back. Nearly half. How, he asked?
They didn’t expect a government that never helped them to help them, had no qualms looting stores and warehouses, lots of Asian neighbors were already experienced eating pets, they had lots of arms and knowledge in using them compared to liberal whites in the suburbs and had lots of makeshift weapons, too, and few qualms killing zombies. Might have taken out some crazy homeless people, too, but the biggest issue was food and that was less of an issue when you can loot, eat anything and many of your neighbors in uptown can be killed or are already shambling zombies ...
Yes like about half of the US right now which is bellow zero.
I don't think frozen zombies get to eat much.
