Okay, say I have actually a castle v a single vampire life in it. They must drink the blood the 5 human beings per day to survive, however they deserve to substitute with animal blood, or by taking tiny amounts from humans so they won’t die, however will have to suck much more humans if they should do so. Yes a nearby town, through a populace growth price of 10% every year, ignoring deaths led to by the vampire. If the vampire demands a population that’s stable, suspect they kill five people a day, climate they’d need to kill 1826.25 people per year.

You are watching: How long can a vampire live

That method that the town population will have to be at least 18263 civilization for the vampire come sustain themselves indefinitely. Let’s put that number at exactly 19000. Exactly how long have the right to the vampire walk without dying, in this model?

infinitely, even at a 0% development rate!5 humans" worth of blood is 25 liters. 25 liters are 50 blood donations.

A usual blood donation is half a liter. Let"s i think one donation every 12 mainly to it is in on the completely safe side.

50 blood donors per day times 12 weeks a 7 work = 4200 human being could keep the vampire indefinitely.

So us don"t require to gain every citizens to donate blood every 12 weeks: assume just a third of the world can donate due to age (too young and too old room the various other 2/3) and we have a 150% that the people we actually should feed our vampire forever available! not sufficient to get him a wife, however every among them only requirements to donate half a liter the blood as soon as every 126 work (about 4 months). That"s a small price for the defense of one immortal!

The city doesn"t also need come grow but can stagnate - as lengthy as it constantly has at least 4200 viable adult donors.

Indefinitely

As lengthy as your vampire doesn"t mind eating old people. The human being who matter is the adults, who room the reproduction stock and the young who are the next generation of breeding stock. The elderly room past breeding age for this reason getting consumed won"t influence future populace growth.

Alternately castle can additionally eat males together a man could have multiple wives so no as plenty of men are required.

It"s no different to what a farmer does. You have your breeding females and also stud males and also older stock and also excess males obtain culled.

Frame challenge: vampires can fast nearly indefinitelyIt is worth noting that vampires are famously reclusive and also can sleep for years if left undisturbed. Vampires in older stories are frequently introduced come the audience while arising from one of these deep sleeps.

So, her vampire constantly has the option of withdrawing indigenous the people if his predations threaten the viability the his food supply. That, and also lying short to protect against detection by vampire hunters, space two the the biggest reasons vampires walk quiet for long stretches.

Few other monsters have actually the capability to "hibernate" because that generations, and I think this capacity is a vital driver that why vampires space generally taken into consideration arch-villains with something choose true political power in the monster world: a werewolf has actually no choice but come announce his existence to the locals every complete moon, however a vampire can always hunker under for as lengthy as the takes because that passions to quiet down and also memories come fade, just to arise rested, refreshed, and also a small wiser around handling prey -- when his latest antagonists are currently old, decrepit, and also likely discredited by society after year of fruitless vampire hunts.

I think no one of this is appropriate to the modern reinterpretation the the vampire, i m sorry is essentially an emo superhero whose goals usually don"t contemplate much beyond the next semester of classes. (And that"s no a knock versus Twilight -- or no just -- it was true also in the "80s.)

The classic vampire is a advanced predator that is characteristically difficult to detect, harder to corner, and also hardest to truly eradicate, because the standard vampire is essentially a normal person who has actually been forced by their scenarios to dedicate their whole existence to relentless serial murder. You deserve to trust lock will use all their guile and cunning to avoid detection and continue killing.

Consider that every vampire starts together an innocent human who is struck by a monster. The after-effects of that strike are hard to important imagine. Spoiler: you can"t simply bandage you yourself up and also get a rabies shot.

As a vampire, your heart is forever damned, for this reason you challenge eternal suffering as soon as you expire, i m sorry is the greatest possible incentive there can be to avoid death. (By contrast, a human has actually a chance at paradise.) This is her life now.At the very same time, staying clear of death has come to be far more complex for you:You have actually a new basic need that culture won"t tolerate: new blood pumped through a dice victim"s still-beating heart. Over there is no app for that.You"ve also taken on a bunch that fatal brand-new allergies: sunlight, divine water & crosses, garlic, and those are just the pedestrian points that have the right to kill girlfriend instantly. Preventing these things -- which most human being love -- constantly endangers to disclose your nature.If anyone ever gets wind of your existence, you can expect lock to form a mob come hunt friend down and punch her ticket come Hell. Civilization who knew your victims might dedicate their lives to murdering you. And also it is the official policy of the Church -- among the most an effective forces on earth -- come exterminate you.

Being turned right into a vampire is the single worst thing that can happen to anyone, quick of personally earning the wrath that almighty God. Together Cicero famously said:

Lorem ipsum dolor sit amet over there is no one who loves pain itself, who seeks after it and wants to have actually it, simply because it is pain...

With that sort of motivation, you have the right to expect every vampire the survives its an initial year to it is in an infinitely desperate, and thus formidable, opponent.
