The pie charts illustrate the proportion of eight common leisure activities in the USA in 1999 and 2009.
Looking at the graphs, it is clear that walking was the most dominant leisure activity among Americans in both years. It is also apparent that indoor activities, including swimming, aerobics, and weightlifting, experienced a significant decline, while soccer and camping exhibited no significant increase.
It can be seen that in 1999, the number of individuals who engaged in walking was highest, at approximately one-third, whereas the proportion of individuals participating in yoga was the lowest, at 5%. Meanwhile, the figure for aerobics accounted for 13%, but it declined to one-third of its previous level in 2009. Similarly, in 1999, jogging contributed 7% on research, which doubled that of the year 2009.
However, the rate of swimming was below one-tenth, but it was double the figure recorded in 2009. Additionally, football and camping experienced a slight increase of approximately 1%, while the number of individuals who participated in bicycling decreased to half of its previous level.
