The graph illustrates the proportion of people visiting a museum at least once a year from 1980 to 2010.
Overall, minor variations can be seen in the surveyed patterns. It is notable that the age range above 50 dominated the chart with leading figures, contrasting with the age range of 15-24.
In 1980, it started at about 46%, and reached a peak at 50% in 1990, which was also the highest spike in the whole period, but then people visiting museums was over 50 dropped steadily over years. 40% was the closing figure for this category, which showed that museum visitors over 50 years old declined after 30 years.
The two age groups had relatively parallel patterns were 25-34 and 35-49. In 1980, both of these categories started with the same figures, nearly 40%. The highest point for 25-34 people was in 1995, with exactly 40%, before it decreased significantly in 1990. After that, the figures of both were stable, with the former most of the time held higher position.
Youngster people aged 15-24 visited the fewest museums in the above categories. Starting with 20% at the beginning, the figure for this age group increased in the following years, and it remained at 35% consistently from 1995 to 2005, before returning to 20% in 2010. This proved that after 30 years, the percentage of museum visitors aged 15-24 was still the lowest.
