Mormons have a widespread cultural practice of prepping, which I understand is mostly the sensible kind where you keep stocks of food and water onhand in case of a natural disaster (rather than the generally-less-sensible rifle militia LARPing). This is something that the institutional Church of Latter-Day Saints encourages among its members, and it strikes me as a pretty good thing to do. Nonetheless, there's no reason why you need to accept the other religious tenets of the LDS church in order to do sensible emergency preparedness, and I'm not sure that not every Mormon community or household is equally diligent about preparedness.
