Wondering how many people attended the concerts at Tons of Rock 2025? We’ve crunched the numbers. So how did we do it? We used the same method applied in political polling, TV ratings, and statistical extrapolation. You take a small sample of the audience and calculate the percentages.
We use data from Setlist.fm, the world’s largest website for concert setlists. With that, advanced algorithms calculate the percentage of attendees based on the number of tickets sold, giving us an estimated attendance figure for each show.
But keep in mind, these are rough estimates. We have limited data to work with, and other factors can influence the results—such as overlapping concert times, certain genres having more active Setlist.fm users, and so on. Still, it gives a general idea.
