The charts show why people in Great Britain visited art museums, and how much each reason accounted for of the total number of people, in 1990 and 2000.

Overall, it is clear that in both year, most people in that country visited museums to learn and gain knowledge. Also noticeable was that over the years, there was a considerable drop in the percentage of people doing the same thing just to fill their travel schedules, going from 27% in 1990 to only 12%.in 2000.

Looking closer at the charts, there were more people going to art museums to spend times with their friends and family in 2000 than in 1990, 17% to 12%. The same pattern can be seen in the proportion of visitors who wanted to attend special exhibits in museums. Its percentage was remarkable higher in 2000 than in 1990, when only 12% of people had that purpose.

People also went to museums to buy art and do some other things, but they only accounted for less than 10% in both surveyed years.
