The bar charr illustrates the proportion of fitness membership between 1970 and 2000 by gender.
Overall the number of male and female fitness membership showed significant differences over the thirty-year period. The figure for male membership fluctuated during the period, rising sharply from over 2,000 in 1970 to 4,000 in 1975, and then dropping quickly to below 2,000 in 1985. After the male membership climbed back rapidly to reach a peak of 5,000 in 1995, it declined drastically to 1,000 by 2000.
In comparison, female membership also showed similar pattern, increasing steadily from 1,000 in 1970 to reach nearly 3,000 in 1985, and then fell markedly to over 2,000 in 1990, before rising back to almost 3,000 in 1995. By 2000, female membership experienced a slight decline, reaching twice the proportion of male membership, at 2,000.
In summary, the changing patterns for fitness membership varied consistently, with male membership accounting for higher proportions most of the times, culminating in 1995, while female membership was higher only in 1985 and 2000. Interesringly, the figures for male and female membership stood at similar level in 1990.
