The line graph given illustrates the proportion of outdoor activities participated in by Australians over a ten-year period from 1997 to 2007.
Overall, picnicking was consistently the most popular activity among Australians over the period, while horse riding attracted the fewest participants. In addition, camping and cycling became increasingly popular, whereas participation in walking showed a downward trend.
The graph clearly shows that in 1997, participation in picnicking and walking stood at approximately 65% and 60%, respectively. Throughout the period, the rate for picnicking decreased gradually to just under 60%, while walking witnessed a significant drop to around 40% by the end of the period. Despite these declines, both activities remained among the most popular choices for Australians.
In contrast, at the beginning, camping and cycling each accounted for approximately 20% of participation. However, there was a noticeable growth in these activities over the 10-year period, with both figures reaching almost 25% in 2007. The increase was steady and moderate, indicating a growing interest in these outdoor pursuits. Horse riding, however, remained stable throughout the decade, with participation consistently at around 8%, making it the least popular activity in all three years shown on the graph.
