The line graph shows the number of people who are aged 65 or above and infected with influenza in a particular village in the UK over a ten-decade period between 1985 and 1995. Overall, it is clear that the figure for elderly people with influenza showed a significant increase, with wild fluctuations, from 1985 to 1995, peaking in 1991.
In 1985, the number of elders with influenza started at 40, and then rose gradually to 55 in 1987. Despite a steady three-year increase, the numbers for people with influenza dropped marginally to 48 in 1988, but this followed by a noticeable growth to 70 in 1990.
In 1991, after a marginal rise, the figure for influenzed people peaked at 75, after which it underwent a considerable decrease to about 60 in 1992. From 1992, there was a mild fluctuation in the number of influenzed in people between 1992 and 1995.
