The line graph illustrates the proportion of visitors among four international museums between 1980 and 2015. The measurements are indicated in millions. Overall, it is evident from the graph that each museum experienced corresponding falls or rises over the period.
In detail, at the beginning of the period, the proportion of Louvre visitors far exceeded those of the other three museums, at just below 8 million. After reaching a peak of 8.5 million in the next fifteen years, the proportion finished by reaching a peak of 9 million, accounting for the highest proportion at the end of the period.
Similarly, the proportion of visitors to the Vatican Museum experienced a dramatic upward trend. It started at just 5 millions in 1980, climbing gradually to around 7 million in 1995, and soaring significantly to finish at almost the same proportion as the Louvre Museum, at 8.5 million in 2015.
The changing pattern of proportion between London Science Museum visitors and Shenzhen Museum visitors was similarly downward, with both starting at just 4 million and 3.9 million in 1980, respectively. Between 1990 and 2000, the proportion for both museums stood in the range of 2.8 and 3 million. However, the proportion of London Science Museum visitors increased steadily to end at 3.9 million in 2015, whereas Shenzhen Museum visitors’ figure decreased moderately to finish at 2.1 million in 2015, accounting for the lowest proportion in the final period.
It can be understood that the Louvre Museum was the most visited next to the Vatican Museum over the time frame. In contrast, the London Science Museum and Shenzhn Museum experienced a decline, with the exception of a difference after 2000.
