The line graph illustrates how the proportions of a museum’s visitors who attended at least once a year, measured by age, varied every five years from 1980 to 2010. Overall, the age group over 50 experienced a decline in its visitor rate, while the other cohorts maintained relatively stable levels throughout the given timeframe. Notably, the oldest group ranked first in terms of museum visit rates, highlighting the contrast between the 15-24 age group and the over 50 cohort.
Visitors aged 15-24 and those over 50 exhibited opposing trends during the surveyed period. In 1980, the youngest age group had a visitation rate of 20%, which rose steadily to around 25% in 1990. This rate remained relatively stable until 2005, before experiencing a moderate drop back to its initial level. In contrast, the over 50 age group started with the highest visitation rate at approximately 48% in 1980 and saw a slight increase to about 50% five years later. However, this rate then underwent a downward trajectory, decreasing to 40% by 2010. Despite this decline, it still had the highest visitation rate among all age groups.
The other middle-aged groups displayed a similar trend. They both began with visitation rates around 38%, before decreasing moderately to 30% in 1990. Following this decline, these groups exhibited an upward trajectory, albeit to varying extents. The age groups of 25-34 and 35-49 increased to 40% and 48%, respectively, maintaining stability for a period of ten years before experiencing a slight downturn back to their initial levels.
