Safer Survival Distance From USA City Hordes

July 28, 2010

During a previous post, Survival Retreat Safe Distance From City, I promised that I would build a USA map of all 276 cities with populations greater than 100,000 people, and draw a 300 mile diameter zone around each city (150 mile radius). After a fair amount of effort, here it is. This will represent my opinion of a worst case disaster scenario where for whatever reason, the hordes are leaving the cities in search of xyz. The majority, at best, will get no further than 150 miles (see the referenced post as to why).

There are two exceptions to what you see on this map. Although I plan to make a project of improving the map, it currently does not reflect the effects of the location and direction of highways  and main roadways (the 150 mile radius – range still applies). For example there are regions within some of the 300 mile zones where there essentially are no roads, or the roads are very minor. Since most of the horde will mistakenly take to the highways, this will create some number of safer areas within some of the zones that are shown.  The other exception is that there are some geographical obstacles and deterrence within some of these zones which most of the horde will not attempt to overcome, such as mountainous terrain.

The purpose of the map is to help identify your risk based on where you live and to help to identify ‘safer’ regions within the USA. I’ve included cities on the southern border of Canada which are populated greater than 100,000 since this may affect some of the northern states of the U.S.

The most surprising and interesting data to come out of this map for me was this… take a look at West Virginia, which is tucked right in the middle of the eastern U.S. and all of its population centers. Notice the good size chunk towards the southern end of the state which is free from any of the 300 mile zones. Huh… Interesting.

The rest is fairly obvious.
