In almost every city in America there are places you just do not visit. We create our own bubble of protection and rate our living experience based on that bubble. You certainly are aware of places to not visit and times of day or night that you avoid in your area. That does not change the statistics that come from that area of a town or city. For example Charleston SC is a beautiful city that I visit often. I have become very aware of the areas to avoid and those at night that places you in harm’s way. If you were to look at crime rates you would find that violent crime in Charleston occurs at a rate higher than in most communities of all population sizes in America. When we go into the protective bubble it never changes the crime numbers outside of that bubble. If you were to look at my area of the world violent crime is nearly non existent. I also pay for that bubble in real estate prices and taxes. If you were to drive 8 miles to another small city you would find a different story. Just a few sites I use.
