Although the seventh Harry Potter book really was the last one, author J.K. Rowling still continues to engage with Harry Potter fans, answering different questions about the wizarding world that fans may have. Since the seventh book really was the last one, though, fans have started making their own magic and letting their imaginations go wild while filling in some of the holes.
One of the Harry Potter fan theories fans have came up with has to do with the small size of Harry’s class. Rowling had revealed to fans that there are only about 1,000 students that attend Hogwarts. This gave fans something to do with their time while they tried to figure out how all of that actually adds up. Since there are only 1,000 students at Hogwarts then there would be around 35 students in each of the houses during the year. However, it was seen that there were only around 10 during the year that Harry Potter was there. Although there could be unnamed students in Harry’s class, a fan thinks this is not likely.
A fan’s perspective on the 10 student class is that there were less during Harry’s year because the other kids would have actually been conceived during the peak of Voldemort’s reign of power. During the time when dozens of adults had joined the order, civilians were killed in the Death Easter raids and many of the adults didn’t want to bring a child into the world during that time. There actually was a baby drought during that time for a few years, which led to a smaller class size during the time that Harry was in school. It’s one of the best movies of all time, and these theories just add to that mythos.
