The graph shows the number of visitors to four international museums between 1980 and 2015

he line graph compares the number of visitors to four museums—Louvre, Vatican, London Science, and Shenzhen—between 1980 and 2015.

Overall, while the Louvre and the Vatican museums became increasingly popular over the period, the London Science Museum experienced a steady decline, and the Shenzhen Museum showed fluctuations with only a modest recovery by the end.

In 1980, the Louvre was the most visited museum, attracting about 8 million people. Its visitor numbers climbed gradually to 9 million in 1995, dipped slightly in 2000, and then rose again to reach a peak of nearly 10 million in 2015. A similar upward trajectory was observed in the Vatican Museum, which grew from roughly 5 million visitors in 1980 to almost 9 million by 2015, despite some minor fluctuations.

By contrast, attendance at the London Science Museum consistently declined, falling from 4 million in 1980 to only 2 million in 2015. The Shenzhen Museum started at the same level as London Science with 4 million visitors, dropped to about 3 million in 2000, but then recovered slightly to nearly 4 million by the end of the period.
