Subsequently, the percentages of the second youngest age group and the oldest age bracket observed a sharp increase, reaching 55% and 20%, respectively. Conversely, the figure for people aged 45 to 54 bucked the trend, falling nearly 9 percentage points compared to 2010. Over the next three years, the level of participation in music concerts rose gradually among those aged from 25 to 44 before peaking at 70% by 2015. The rate of attendees in the 45-54 age category hovered around 30% between 2011 and 2013, followed by a rise of approximately 18 percentage points. Furthermore, despite decreasing, the figure for the oldest age cohort saw a small rebound, amounting to 20% by 2015.
Regarding the 16-24 and 55-64 age categories, in 2010, concert attendance figures for the youngest age demographic constituted 52%, overtaking the latter by a wide margin of 25%. The attendance percentage of individuals aged between 16 and 24 leveled off around 40% to 52% throughout the surveyed years, reclaiming its initial figure (52%) by 2015. Moreover, the rate of concert-goers among those aged 55 to 64 reached its peak at 30% before dipping to 20% by 2015, becoming the only group with a decline trend.
