As of 2018, over half of the world's population lived in or near large urban centers. For myself and others, urban survival is a necessity and not so much an option.
Depending on the scenario, survival in the city and suburbs is very possible and in some situations, it's the best choice.
This is not to say that wilderness survival skills are not necessary to cultivate, however the reasonable course of action is survival in your area of operations, your home turf.
Success hinges on knowledge of the area, routes of traffic, resources and human network.
