The graph illustrates the data on individuals by different age groups watching the film in the cinema at least once a month from 1978 to 2008. Overall, while all age groups experienced fluctuations, both the 25-34 and 35-49 age groups showed the most notable variations, whereas the 50+ age group had the lowest percentage of cinema-goers but displayed a steady upward trend.
Regarding age 14-24, it remained relatively stable over time and there was a variation between 86-90% over the years before dipping slightly to 86% in 2008. Age 25-34 experienced an erratic pattern, starting at 80% in 1978, witnessing a downturn to 59%, and later rebounding to about 80% before easing slightly to 76% at the end of the period.
For the other two older age groups, both groups followed a similar pattern. Age 35-49 and age 50+ categories both saw a significant drop in 1988, at 50% for the former and at 30% for the latter. However, they showed a steady rise afterward, with the age 35-49 group finishing approximately at 58%, while the 50+ group steadily climbed to 51%.
