The two pie charts compare how people in the United States spent their free time on eight different sports activities in 1999 and 2009.
Overall, walking was the most preferred activity in both years, showing only a slight increase over the decade. In contrast, yoga consistently remained the least favored activity. There were also noticeable changes in activities such as swimming, aerobics, and jogging.
In detail, walking accounted for the largest share of free-time activities, rising slightly from 29% to 31%. Soccer and camping experienced minimal growth, each increasing by only 1%. Swimming, however, showed a significant rise, doubling from 9% to 18% over the ten-year period.
On the other hand, aerobics saw a dramatic decline from 15% to 5%, becoming one of the least practiced activities by 2009. Jogging also decreased sharply, dropping from 14% to 7%, almost half of its original figure. Bicycling fell slightly to 7%. Meanwhile, yoga and weightlifting switched positions, with yoga decreasing to 3% while weightlifting doubled from 5% to 10%.
