The provided bar chart illustrates the percentage of concert attendees in a specific city, categorized by age group, from 2010 to 2015.
Overall, the proportion of individuals attending concerts generally increased across most age groups, with the exception of those aged 55-64, which experienced a decline. Attendance was consistently highest among the youngest age group (16-24), while the 75+ age group consistently remained the lowest throughout the period.
In 2010, the 25-44 age group exhibited the highest attendance rate, at slightly above 50%. However, this figure declined steadily to a low of approximately 40% in 2014, before recovering slightly in 2015. Conversely, the 75+ age group, despite exhibiting the lowest figures, experienced a twofold increase from approximately 10% to 20% over the five-year period.
Meanwhile, the 16-24 age group recorded the most significant growth, rising steadily from 40% in 2010 to slightly over 70% in 2015 — the highest rate among all groups by the end of the period. A similar upward trend was observed in the 45-54 age group, increasing from 40% to nearly 60%; however, this group experienced a slight dip between 2011 and 2013.
In contrast, the 55-64 age group demonstrated a consistent decline in concert attendance, decreasing from 25% to approximately 22% by 2015.
