The Walking Dead: 10 Giant Plot-Holes You Probably Missed

2. There Can€™t Possibly Still Be These Massive Hordes Of Zombies Still Wandering Around

The opening of season six featured numerous shots of an absolutely enormous zombie horde descending onto Rick and his group. But having been a few years since the outbreak of the apocalypse on the show, there is no realistic way that there are still that many zombies still wandering around in America. Using America's estimated population of 320 million and assuming that 99% of everyone is infected, that leaves 3.2 million survivors and 316.8 million zombies. Assuming that the survivors are scattered into little groups and each group is around 20 people, that means that there are around 160,000 groups. Now based on the attack rate of the zombies seen on the show, assume that each survivor will kill around 10 zombies on average per month. This works out to be 200 zombies killed per month per group, which works out to be around 2,400 dead zombies a year per group. With 160,000 groups and 2,400 dead zombies a year, that means that there should be about 384 million dead zombies in America after a year. Huh, so despite running around and still getting ambushed by zombies everywhere, the maths says that there shouldn't be any zombies left at all. Of course this is just some simple math based on some simple assumptions, but if the math hasn't convinced you why the Walking Dead should actually be over by now, then maybe the next entry will...
