The bar chart illustrates how many visitors went to a museum, categorized by three types of visitors over a 15-year period starting from 1997. Overall, it is obvious that the number of adult visitors and special exhibition visitors experienced upward trends, while the reverse pattern was seen in the figure for visitors aged under 15. Notably, adults preferred visiting the museum over the period shown.
Examining the specifics, in 1997, there were about 300,000 adult visitors going to the museum, more than twice as high when compared to the figure for visitors below 15 years old. Meanwhile, special exhibition audiences were the lowest, with only 28,000 visitors.
In the following years, the number of adult visitors increased slightly and peaked at 400,500 in 2007, before falling to 380,000 at the end of the period. Special exhibition attendance rose to 42,000 visitors by 2012. Besides, visitors below 15 years old witnessed a drop of approximately 40,000 during the given period.
