survival rates.

Is this based on what amount of stocked food people have lying around or did it also calculate their capability to go out and find food if they can?
Because there are very limited scenarios that would force a person to live in a bunker or locked in their house, and those involve the extreme scenarios of radioactive fallout, or being in a state of siege with outside insurgents. A tsunami for example might even tear down the house altogether if you're not using an underground bunker. So everything you've stocked might be awashed away along with yourself. Survival rates in this case: slim.

People must have a backup plan other than stocking food, for the propable scenario where things never return to normal...

 

This is pretty interesting. I'm surprised this many Americans have so little food in their homes though! I thought we all stocked up on everything! I have never had less than 3 days of food in my house, even when I was in college living in the dorms! Hmmm, maybe I stock up too much? Fascinating stats @lonewolf

 

If survival is a major concern fo these people. Self sustainance is the way to go. Stocked food is, of course, limited, and really it doesn't matter how much food you will have given an indefinite critical situation, like, for example getting lost with slim chances of being rescued soon. Really

 

I'm good for around 5/6 months 'generally' but I'd be pretty fed up by the end as I am top heavy on meal 'bulkers' such as pasta/rice etc., and this is the area I need to focus on over the coming months to get things balanced out again.

 

Well, I haven't been to the store for a bit but I normally have at least a month worth of food in my cabinets. Now, if I were to have an emergency situation, I could easily make that food stash last me longer than that. This actually concerns me a little that there are so many of us (myself included at the moment) that would just wither away of they only relied on what they have in their cabinets now. For the 75% that said they would be dead in 2 months, you should probably join this forum to learn some quick tips on how to make it longer than that.

 

Most people don't envision worst case scenarios when planning even for a business. This is due to the easy availability of foodstuffs from the various stores. This lack of preparedness can also be attributed to the fact that government agencies usually give forecasts or warnings of adverse conditions when they are about to happen and this is the time most are likely to stock up.
