The line graph illustrates the proportion of individuals from various age demographics who attended gyms at least once per month between 1984 and 2003.
In general, the data indicates a marked upward trajectory in gym participation across most age groups, with the notable exception of the 46-65 cohort, which exhibited a decline. Additionally, the elderly demographic, those aged 65 and above, consistently represented the smallest proportion of gym attendees throughout the entire period.
As can be seen in the line chart, in 1984, approximately 10% of the 18-25 age group engaged in monthly gym visits, a figure that considerably surpassed the modest 5% of the 65+ category. Over the years, gym attendance among the younger cohort demonstrated a steady and sustained increase, reaching a peak of 52% in 2003, the highest percentage recorded across all age groups. In contrast, the participation rate for the 65+ demographic initially rose slightly, peaking at 15% in 1994, before declining to 10% in 1999, and subsequently stabilizing at 15% by the end of the period.
Focusing on the intermediate age groups, those aged 26-45 started at 25% in 1984, gradually ascending to a high of around 43% in 1999, before experiencing a minor uptick to roughly 45% in 2003. Conversely, the 46-65 age bracket commenced at 17%, displayed fluctuations throughout the observed timeframe, and ultimately concluded at just 18%, the lowest figure recorded across all metrics.
