The provided graph illustrates the participation rates in four distinct sports over a twenty-year period from 1985 to 2005 in a specific region.
Overall, the data reveals a fluctuating trend in participation levels across the sports, with tennis demonstrating consistent growth, while rugby experienced a significant decline.
In detail, rugby commenced with the highest participation rate of 250 individuals in 1985; however, it exhibited a downward trajectory thereafter, dropping to 230 in 1990, and further decreasing to 200 by 1995. Following a dramatic decline, participation plummeted to just 100 in 2000, culminating in a mere 50 individuals participating by 2005. Conversely, badminton witnessed a steady decline throughout the period, starting at 85 participants in 1985, and gradually diminishing each subsequent year to reach a plateau of 70 participants by 2005.
In contrast, tennis demonstrated remarkable growth, commencing with 150 participants in 1985 and rising annually, peaking at 250 participants by 2005. The most notable increase occurred between 2000 and 2005, where the number surged from 240 to 250. Basketball reflected a relatively stable trend, with initial participation remaining constant at 50 from 1985 to 1990; however, it experienced a modest rise to 60 by 1995 and 2000, before finally increasing to 70 participants by 2005.
