This is a thought provoking thread. I see safety as relative, and depends a lot on where you are. Working in SE Alaska as an example, is a place with daily encounters with bears, wading fast rivers, and falling down about once per hour. There are wolves, wolverines, and a really cold and wet climate far from any help.
Urban environments definitely have their own perils, but most people are adapted to them, and deal with them as part of their daily routine. Using disease statistics are not really relevant because it takes a lifetime for the mortality to show up. I would make the point that remote wild countlry should never be taken lightly. Keep your wits about you where ever you are. People that have been 50 miles from the nearest dirt road know I am talking about.
Looked at another way, most people get killed in urban environments because that is where they spend 99 % of their time, not because it is much more dangerous. I have been assigned work partners in places like Alaska that were accidents waiting to happen because they were way out of their comfort zone.
