The given bar chart illustrates the changes in the number of three distinct groups of visitors to a museum from 1997 to 2012.
Overall, the number of adult visitors ranked the highest among all categories, while the figures for special exhibition visitors saw the opposite throughout the period. In addition, the number of all tourists fluctuated through each stage and reached its peak at 525,200 in 2007.
In 1997, about 480,000 people visited the museum, after which it witnessed a slight decline to 441,000 in 2001, before experiencing a sharp increase to 525,000 and then dropping slightly to 504,000 in 2012. Meanwhile, the figure for visitors aged over 15 followed an upward trend, with exactly 300,100 people in 1997, then increasing modestly to about 302,000 in 2002, before growth significantly to 400,500 in 2007 and ending the period at 380,000.
Looking at two other categories, it is clear that while visitors aged under 15 experienced a downward trend, special exhibition visitors showed an opposite trend . In 1997, the number of visitors aged under 15 was about 5 times higher than special exhibition tourists, with 120,000 and 28,000 respectively. However, by the end of the period, the figure for those under 15 had dropped to just approximately twice as many as that of the special exhibition group, at about 82,000 and 42,000 respectively.
