Would Southern Nevada survive a zombie apocalypse?

You never know what can happen — whether that's rain, sleet, snow or a zombie apocaplypse.

Well, maybe not zombies.

Just in case, to help zombie-obsessed fans assess their chance of survival, the Washington Post has put together a county-level index of "survivability," should an actual zombie apocalypse plague the country.

In order to determine the survival rate for each county, the index took into consideration five variables:

Low population density
Access to guns
People with military experience
Terrain that's difficult for zombies to traverse
Access to bodies of water

Keeping the weight of importance for each variable completely even, Nevada, as well as the Southwest, fair pretty well on survival in comparison to the east coast.

One of the main reasons residents out west have a higher chance of survival than their counterparts on the east is due to population density. With the exception of a few cities, the Southwest isn't nearly as densely populated as the east coast.

It's theoretically less work for a zombie to find victims in an area where places and people are right on top of each other, rather than out west where it isn't uncommon for homes to be vastly spread out.

Another variable that helps the Southwest is their access to guns. With less people residing in the area, there is more of an ammo supply available, according to the highly unscientific analysis.

Based on the variables used to determine survival, with the exception of Clark County, both Southern and Northern Nevadans have an extremely high chance of living to see the end of a zombie apocalypse.

Unfortunately for Las Vegas and Henderson, Clark County fairs terribly when it comes to surviving a zombie outbreak. Although it could be worse — Orange County, California is "way, way, way below average" — according to the variables, the region is "a little below average" on survivability.

Among the factors working against Clark County is the lack of access to bodies of water, high population density and the lack of difficult terrain.

Clark County's scarce water supply would be a hindrance to the area's survival. Although, the area does have an abundance of swimming pools, which could come in handy considering zombies are (usually) incapable of swimming.

Outside of Red Rock, Mount Charleston, Lone Mountain and Sunrise Mountain, Clark County doesn't have much in terms of high-ground. Because the area is pretty flat, zombies wouldn't have difficulty navigating and traveling through the region.

Along those same lines, a zombie plague would spread quickly due to how densely populated Clark County is. Like the outbreak in "Shaun of the Dead," Southern Nevada's neighborhoods make it easy for zombies to move house-to-house in no time, with little effort.

However if you happen to be a resident of Nye, Lincoln, White Pine, Eureka, Pershing, Churchill, Mineral or Esmeralda counties, you have nothing to worry about.
