The Bare Minimum There are a huge number of variables that will make your specific needs and responses different from mine, and that’s expected. You might be older or younger, or have more or fewer monetary resources, or live in a drier or hotter or colder environment. In other words, I don’t have a magic and specific list of things that everybody and anybody needs. Except these, which everyone should have:
A minimum of three months of food per person in your household stored, covering about 2,000 calories per day per person. A plan for where to go in case where you are currently living becomes unsafe.
A minimum of three months of emergency funds in cash safely stored outside of the banking system.
A deep pantry and a deep basement, filled with the things you normally consume to combat both potential scarcity and inflation (see #1).
Three weeks of stored water and a water filter sufficient to create clean drinking water for you and your family with enough replacement filters to last a year.
The ability to keep yourself warm in winter should your heating systems fail or be too expensive (blankets, sleeping bags, wool sweaters, etc.) and the means of keeping cool in summer that’s not A/C. The ability to defend yourself and your family from violence.
That covers the bottom layer of Maslow’s hierarchy of needs, which is physical survival. Truthfully, everyone should have those basic precautions anyway, especially people who live in areas prone to natural disasters.
