The given bar chart breaks down the numbers of tourists coming to a museum by three different guest types from 1997 to 2012. Overall, the total number of guests visiting the museum witnessed a slight increase with upward trends of all categories, except for the number of under-fifteen visitors. Notably, the number of adult visitors remained the largest during the whole period.
To be specific, in 1997, there were 300,100 adults visiting the destination, claiming the first position in the bar chart. After five years of no significant change, the figure for adult visitors climbed to its highest point of 400,500 people. Then, it fell modestly to 380,000 people in 2012, remaining the largest number over the period. This also led to an increase in the total number of guests at the end of the period, from 448,100 to 504,300 people.
Turning our attention to the remaining two visitor types, in 1997, the number of children under fifteen started at 120,000, about four-fold higher than that of Special Exhibition visitors. However, during the period, the two categories experienced distinctive trends, which caused the number of under-fifteen tourists to diminish to 82,300 and that of Special Exhibition visitors to rise slightly to 42,000 people, closing the gap to a two-fold difference. Nevertheless, the number of visitors coming to the Exhibition remained the smallest group in the bar chart after the provided period.
