The given graph illustrates the influenza addiction case study in a specific village, focusing on individuals aged over 65 in the United Kingdom from 1985 to 1995. The data highlights significant shifts in percentages related to influenza addiction, revealing notable trends in rural areas throughout the decade. The graph reached its peak in 1991.
The most noticeable trend is that the graph started from a lower point and then, during the middle period, reached its highest point. Following that peak, there was a substantial decline in the number of cases.
In 1991, over 70 individuals were affected by influenza, while the previous year recorded exactly 70 cases. However, the starting year, 1985, saw only 40 cases, which was the lowest number reflected in the graph.
In 1987, the reported number of influenza cases was approximately 55. In contrast, the previous year, 1986, saw 45 cases, and the following year the number decreased to around 48 individuals.
Furthermore, in the final year of the study, the number of affected individuals slightly decreased compared to the middle years. In 1992 and 1993, the graph indicated similar levels of influenza cases, with the numbers at 60 and 61, respectively. Additionally, in 1995, the graph displayed a downward trend.
