The bar chart delineates the number of male and female fitness memberships over a thirty-year period, from 1970 to 2000.
Overall, both categories exhibited distinct trajectories, with male memberships demonstrating a sharp upward trend in the later years, culminating in a peak, while female memberships showed a more moderate and fluctuating increase throughout the period.
In 1970, male memberships stood at approximately 2,000, modestly exceeding female memberships at around 1,000. By 1975, male figures rose to nearly 3,000, though they subsequently experienced a decline to just above 2,000 in 1980 and below 2,500 in 1985. This value stabilized at 2,500 in 1990 before surging dramatically to just above 5,000 in 1995, representing the most pronounced increase over the period. By 2000, male memberships had escalated further to almost 6,000, the highest recorded value.
Conversely, female memberships exhibited a steadier, albeit fluctuating, upward trajectory. Starting at approximately 1,000 in 1970, the figure rose to just below 2,000 in 1975, before dipping to 1,000 in 1980 and then recovering to just below 2,000 in 1985. A slight increase to slightly above 2,000 was observed in 1990, followed by a further rise to just below 3,000 in 1995. By 2000, female memberships had reached just above 2,500, marking a more moderate peak compared to male membership growth.
