For example, have you considered the need for feminine products?  What about canes, walkers, and manually operated wheelchairs?  Pets need food, crates, and toys to keep them occupied while the rest of family members are recovering from chaos.  It will be impossible to cover every contingency but be aware of what those needs are now then prioritize those that you deem most important.

The increased inflation rate in the 1960s, the US monetary devaluation, the continued concern over a possible nuclear exchange between the US and the Soviet Union, and perceived increasing vulnerability of urban centers to supply shortages and other systems failures caused a number of primarily conservative and libertarian thinkers to promote individual preparations. Harry Browne began offering seminars on how to survive a monetary collapse in 1967, with Don Stephens (an architect) providing input on how to build and equip a remote survival retreat. He gave a copy of his original Retreater's Bibliography to each seminar participant.[citation needed]
After examining their new house — “Decent elevation, but not too solar-friendly” — Mr. Edwards issued his analysis. The Dosters rely on electric power for their heat and water, and given the prevalence of long winter power failures in their town, Mr. Edwards recommended a 60-gallon Aquatank water-storage mattress for under the bed. He also suggested at least 10 boxes of Nuvona emergency food and advised the couple to invest in two electric bicycles, energy-saving lights (“If you want to get jiggy with it, try the LEDs”) and a rooftop windmill for alternate generation.
PACKAGE CONTENTS: Bag contains everything 2 people need to survive with no food, water, or electricity for 3 days; Package includes (2) Datrex food bar packs 2,400 Kcal, (12) Datrex water packets 125mL each, (2) ponchos, (2) glow sticks, (2) foil blankets, (2) dust masks, (1) 36-piece first aid kit, (1) radio/light/charger, (1) hand warmer 2-pack, (1) 5-in-1 survival whistle/compass, (1) multiuse pocket knife, and (1) backpack
This is a good assortment of easily prepared food for camping or emergencies. That said, this will not feed an adult for one month. If I have done the math right, there are 19,560 total calories which equals 1956 calories per day for 10 days. So, three of these boxes would feed an adult for a month, if that person was doing only light physical activity. Also, the food bags are not re-sealable, so you should add some quart-size food bags to the box.
What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
