* No official tracking: There's no central database that tracks every book sale or library checkout.
* Different formats: The books are available in various formats (hardcover, paperback, ebook, audiobook), making it difficult to track individual sales across all platforms.
* Secondhand sales and borrowing: People borrow books from libraries, buy them used, or pass them on to others, which are difficult to quantify.
However, we can look at some metrics to get an idea of its popularity:
* Sales figures: "The Hunger Games" has sold millions of copies worldwide, making it a global bestseller.
* Movie adaptations: The movie series based on the books further boosted its popularity and likely introduced many new readers to the story.
* Cultural impact: The book has become a significant part of popular culture, with its themes and characters widely discussed and analyzed.
While we can't know the precise number, it's safe to say that "The Hunger Games" has been read by millions of people worldwide.
