[Vampires General] I can't square the math on how many people Vampires kill, yet still manage to keep secret that they exist. The number of casualties is astonishingly high to go unnoticed. Discuss?

So, vampires drink blood, usually killing the person. Depending on the specific mythos it is more or less lethal, and the cravings for human blood more or less strong. For example, in Preacher, Cassidy doesn't have to drink blood at all except to heal from mortal injuries, whereas in something like Buffy, vampires kill humans every night pretty much. 

So, one vampire killing on average one person per night, lets say they have Sundays off and call it 333.3 people per year, that's 3333 people in a decade. Now if there are lot's of vampires, you can see how the numbers would get quit high. Even 50 vampires in a city is ~16,000 deaths in a decade. Someone's gonna notice!

How are vampires able to maintain the illusion they don't exist if they cause this much impact? Human farms? Mass hypnosis/corruption? It seems like it would never be enough with these kind of numbers! If they don't need to kill it helps on the one hand, but also living victims is more potential to expose them. 

Just some thoughts as I was thinking about vampire math...

Well for starters, they don’t have to drink every night. And let’s say they don’t kill a lot of the time leaving “drunks and junks” behind. People who call in sick the next day and live on as if nothing happened.
A lot of the violence is blamed on gangs and drugs so that matches. And if people die well.. it’s  gangs. Vampires tend to feed on people that won’t be missed or whose death is easy to explain.

In some instances there’s an elaborate masquerade. Where rules of a vampire society make sure they live unnoticed and undisturbed. When a vampire breaks those rules the others punish him swiftly and harshly. 

In the end, the numerical advantage means that a war would be won by humans. And all vampires want to prevent that.
