The line chart provided illustrates how aged people in the United States spent their leisure time from 1980 to 2010.
Overall, the reading, hiking, surfing the internet activities witnessed a significant upward trend, while watching the TV and the theater experienced a more moderate change, which is also downward. Another interesting point is that the rotation for hiking was much more stable compared to the other activites( reading,watching the TV, the theater, surfing the internet ).
Looking at the the details, with respect to hiking, the percentage went up steadily from the start to the end of the period, from just over 20 to about 80. Despite the figure increasing gradually for both surfing the Internet and reading from 1980 to 1990, from approximately 5% and roughly 30% to almost 40% and nearly 10% respectively, second activity fell significantly by half by 2000, while the first one kept about the same rate and reached about 15%. Thereafter, both activities rose dramatically to around 50% for surfing in the internet and almost 60% for reading in 2000.
Similarly, regards watching the TV , the percentile climbed up slowly from just about 60 to 70 between 1980 to 2000, followed by a paltry decrease to round about 65% in 2010. Interestingly, the figure for the theater dipped crucially from just under 50% to a little more than 30% in the first decade. In the next ten years there was a steady increase to more than 40%, and then the figure jumped more marginally between 2000 and 2010 to more or less 45%.
