For reference, here are two questions that deal with wizarding population: [What is the total wizarding population during the events of the *Harry Potter* series][1] and [How many people worked for the Ministry of Magic?][2]

The British Wizarding population seems rather small. Apparently the entire student body of Hogwarts is able to fit into the Hogwarts Express (According to Pottermore -- [**[1]**][3], [**[2]**][4] -- the Hogwarts Express is the only way to Hogwarts; it's not like some students ride the train and some students are dropped off by their parents for the school term.).

**How many wands would Ollivander have to keep on hand at any given time?** We know Harry tried out a lot of wands before his wand finally chose him. Maybe some kids need five tries; maybe some get the right wand on the first try. And there are broken and lost wands that need replacing to take into consideration. 

I don't consider the movies canon, but as they're JKR approved, *Harry Potter and the Sorcerer's Stone* shows Ollivander has a pretty significant number of wands in stock for what is a smaller Wizarding population (see pics). **Is there a canonical way to estimate how many wands Ollivander would need to keep in stock?**

I'm looking for an answer grounded in canon, meaning the novels, interviews with J.K. Rowling, or information from Pottermore or the like. Barring that, a speculative answer in the spirit of canon is absolutely welcome, including alternative sources of information. ETA 12.21.14
