This is my Ielts writing task 1. Could you please review it? Thank you so much.

The line graph compares the percentage of people in four different age brackets who went to a cinema at least once a month between 2000 and 2011. The groups are children 7-14, adolescents 15-24, young adults 25-35 and older adults over 35.

Overall the highest percentages are in the adolescent group, followed by the children, and the young adults. The group with the smallest proportions are the older adults. Attendance rose for all age groups, with the adolescents having the greatest relative change.

In detail, in 2000, less than one in five people of any age group went to see a movie one or more times a month. In the youngest two groups, for example, it was 10 and 15%, and less than 5% for the older groups. There were two large gaps, the first between the 15-24 age groups and the second highest, the children. This was as much as 20%. There was also a gap as large as 20% between the young and older adults. In 2011, the majority of the adolescents were frequent movie-goers, compared to 30% of the next two groups, by age, and about 13% of the oldest group.
