Band 7+: The line graph below shows how elderly people in the United States spent their free time between 1980 and 2010. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph compares leisure time activities among elderly people from 1980 to 2010. Overall, all activities saw significant increases, except for watching TV and going to the theatre, which remained relatively stable. Of note, hiking showed continuous growth throughout the period.

Initially, indoor activities such as reading, surfing the internet, and watching TV gained popularity. For instance, the percentage of people who enjoyed surfing the internet increased from 5% in the 1980s to 15% in the 2000s, with a sharp rise from the 2000s to the 2010s.

Reading showed some fluctuations between the 1980s and 2000s but ultimately increased by 60%. Watching TV, the most popular activity in the early 1980s, saw little change over the two decades.

On the other hand, going to the theatre was also popular, with a 50% participation rate in the 1980s. However, it declined significantly in the 1990s before stabilizing and increasing from the 1990s to the 2010s. Hiking, which attracted only 20% of people in the 1980s, experienced a sharp increase, peaking at 80% in the 2010s.
