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