The line graph illustrates the rate of individuals, categorized by four age brackets, who went to the cinema at least once a month in a specific nation from 1978 to 2008. Overall, while the percentages of people in 25-34 and 35-49 age groups experienced a decline throughout, the reverse trend was recorded for the two remaining age brackets. Additionally, people aged 14 to 24 consistently visited the cinema the most among the given groups.
Regarding the categories that decreased, the proportion of citizens aged 14-24 visiting the cinema was the highest in 1978, at over 90%, exceeding that of people falling into the 25-34 age group by around 10%. In the next two decades, the former experienced some slight fluctuations, followed by a decrease to conclude the period at roughly 85%. Similarly, but to a more noticeable extent, the latter underwent a continuous decrease to a low of nearly 60% in 1988, before rebounding back to its starting level in the next ten years. This level stayed unchanged until 2003, when it slightly descended to approximately 75% in 2008.
Turning to the remaining categories, commencing at 60%, the percentage of cinema visitors aged 35 to 49 gradually declined by 10% in 1988. This was followed by a significant increase to nearly converge with that of people aged 25-34 in 1993 and reach a peak of 70% in 1998, prior to a minor downswing to end at roughly 65%. Similarly, despite descending from over 40% in 1978 to a low of 30% in 1988, the figure for people aged 50 and over experienced a significant recovery to 50% in the following ten years. This level stayed relatively unchanged until the end of the given timeframe.
