Another day, another "Harry Potter" fan theory.

The "Harry Potter" fandom might be the most passionate fandom out there. Fans are constantly re-reading the books, watching the movies, and dissecting every tweet from Queen J.K. Rowling to see if it's a clue about any more potential books. She even created a website for all wizard loving pure-bloods and muggles alike, Pottermore!

Many fans might remember back in 2000, when Rowling said in an interview that roughly 1,000 students attended Hogwarts School of Witchcraft and Wizardry. However, why does it feel like every time we watch the movies, or read the books, it always seems like there are so much less?

At any given time, there were maybe 18 to 20 kids in a class. So, if you do the math...

1,000 students / 7 years at Hogwarts = 143 students per Hogwarts House

Then...

143 students per Hogwarts House / 4 houses = 35.75, so about 36...unless there's someone who had an incident while Apparating.

Okay, so now that math class is over, why are there are only half in class. Lucky for you, one HP fan had an epiphany and thinks they discovered why there were so few students during Harry's time at Hogwarts.

Needless to say, that's a really sad thought. However, if history repeats itself, there is usually a baby boom after a war!
