The bar chart illustrates the fluctuations in visitor numbers to a museum over a 15-year period, from 1997 to 2012, categorized into three groups: adult visitors, visitors aged under 15, and those attending special exhibitions.
Adult visitors consistently formed the largest group throughout the period, with a notable surge from 302,200 in 2002 to a peak of 400,500 in 2007, followed by a slight decline to 380,000 in 2012. In contrast, the number of visitors aged under 15 exhibited a gradual downward trend, decreasing from 120,000 in 1997 to 82,300 in 2012. Special exhibition visitors, while the smallest group, showed a steady increase, rising from 28,000 in 1997 to 42,000 in 2012.
Overall, the chart highlights a significant disparity in visitor numbers across the three categories. While adult visitors remained dominant, their numbers experienced a period of rapid growth followed by a slight decrease. Conversely, child visitors declined steadily, and special exhibition visitors demonstrated consistent growth throughout the period.
