How prepared are typical households for sudden emergencies like power failures?
I would say most households are fairly ill-prepared nowadays because we take uninterrupted utilities for granted. People tend to assume any power failure will be resolved within minutes, so they rarely stock emergency supplies. In regions prone to extreme weather, residents do tend to keep non-perishable food and alternative lighting handy, but urban dwellers usually leave disaster preparedness on the back burner until something actually goes wrong.
