I have 5 and 3 I would want to take in if needed.Safe bet I suppose is to prep for 10.The thing is I am opposite of you and I will not help out anyone who has not prepped a bit.
Unless we have a war situation or some MAJOR weather related mess I just don't see large populations starving in the U.S.
I have checked out those sites with the calculators.I am way behind.Maybe enough for 10 for 2 months tops.Less people more time.More people less time. I always buy an extra bag of rice,beans,soup,sweets for the pantry.It has come in handy on bad weather days when going out is not a good idea.
How is your (extended)family and friends when it comes to stocking the home? Do they all do it,or do they have just enough of everything for a few days?I have some that buy extra and some that just keep on saying," Yeah I should stock up on food and supplies." but they never get around to it. I even have one who always says," I will just come to YOUR house,because I know you have food,supplies,meds,and so on....." It is a bit frustrating given that most I know make far more than we do.They could be doing so so much to prep for those common unexpected things,but they simply choose not to

h well.
As for foods I have so far these types of things,but no idea on the pounds........rice,various dried and canned beans,canned veggies,canned and dried meats,sugar,salt,barley,oats,soups(bagged,canned,dehydrated),spices,honey and honey comb,granola,dried fruits,various nut butters and hazelnut coco spreads,coco powder and hot coco mixes,coffee,tea,wheat berries,popcorn kernels,various vinegars,various oils,pickled veggies,seaweed,nuts in shell,crackers,vitamin c,candied ginger,dried milk and milk in shelf stable cartons.....that is all I can think of at the moment.Oh and wine,blackberry brandy,and vodka.
