The Great Stanford Buffy Population Equilibrium Study

Brian Thomas, a PhD candidate in ecology at Stanford University, has done an ecological analysis of humans and vampires in Sunnydale, the home of Buffy the Vampire Slayer. He took some initial assumptions on rates of population growth, vampire feeding, etc and plugged them into a differential equations model. What he got was an equilibrium human population of 36,346, and an vampire population of around 18, and furthermore the equilibrium is stable. His conclusion was that even though the show’s designers are not ecologists, they managed to come up with ideas that actually made ecological sense — via Slashdot
