The line graph delineates the proportion of individuals from various age demographics who frequented gyms at least once a month between 1984 and 2003.
Overall, the data reveals a significant upward trend in gym attendance among most age groups, with the notable exception of the 46-65 age category, which experienced a decline. Furthermore, the elderly population, aged 65 and above, consistently represented the smallest percentage of gym-goers throughout the observed period.
Focusing on the youngest and oldest demographics, in 1984, approximately 10% of the 18-25 age group frequented gyms monthly, which markedly surpassed the mere 5% of individuals aged 65 and above. Over the years, gym attendance among the younger cohort exhibited a sustained increase, culminating at around 52% by 2003, the highest percentage recorded across all age groups. Conversely, the percentage of the 65+ age group initially experienced a slight rise, reaching 15% in 1994, but subsequently dropped to 10% in 1999, before stabilizing at 15% by 2003.
Regarding the intermediate age cohorts, individuals aged 26-45 commenced at 25% in 1984, progressively ascending to a peak of approximately 43% in 1999, before retracting to around 45% in 2003. Meanwhile, the 46-65 age group started at 17%, saw fluctuations, and ultimately concluded the period at only 18%, representing the lowest figure observed across the metrics. Notably, this demographic was the only group that did not align with the overall trend of increasing gym attendance.
