How many people attend music festivals in Spain each year?

How to get close to this number

Multiply festivals by attendance. The country hosts hundreds of festivals a year, ranging from a few thousand attendees to well over a hundred thousand for the largest. A few hundred events averaging tens of thousands each produces a total in the millions, which is the right scale.

The density point in the explanation is what makes the figure notable: relative to population, this is one of the densest festival scenes in Europe. Climate does most of the explaining — a long reliable summer makes outdoor multi-day events viable in a way it is not further north, where festivals are fewer and weather is a permanent financial risk.

The industry consequence is the structural one: live music now earns more for the sector here than recorded music does. That inversion happened across the industry as recorded revenue collapsed and then only partly recovered through streaming, and it is why touring schedules, not album releases, now drive an artist's calendar.
