The bar chart illustrates the proportion of fitness memberships by gender between 1970 and 2000.
Overall, the number of male and female fitness memberships showed significant differences over the thirty-year period. The figure for male membership fluctuated, rising sharply from over 2,000 in 1970 to 4,000 in 1975, and then dropping quickly to below 2,000 in 1985. After climbing back rapidly to reach a peak of 5,000 in 1995, male membership declined drastically to 1,000 by 2000.
In comparison, female membership also showed a similar pattern, increasing steadily from 1,000 in 1970 to nearly 3,000 in 1985, and then falling 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 2,000, which was twice the proportion of male membership.
In summary, the changing patterns for fitness memberships varied consistently, with male membership generally higher, peaking in 1995, while female membership was higher in 1985 and 2000. Interestingly, the figures for male and female memberships were similar in 1990.
