Average Candidate Response
This graph shows that death rates from Alzheimer’s disease have increased in the ten year period from 2000 to 2010, and additionally as one gets older the mortality rate with Alzheimer’s disease is greater.

The graph has a title related to deaths due to Alzheimer’s Disease in the USA. It is a bar graph, with three age categories along the x-axis, and the death rate per 100,000 people on the y-axis. There is also a colour scheme evident, with blue bars representing the death rate in 2000, and green bars representing the death rate in 2010. The two different coloured bars represent a 10-year difference, and show a change in death rate. Between the ages of 65-74, the death rate due to Alzheimer’s is the lowest, and there is no large increase between 2000 and 2010. Between the ages of 75-84, the death rate due to Alzheimer’s is higher in both years of 2000 and 2010, with an increase of approximately 40 more deaths per 100,000 population between 2000 and 2010. The age range of 85 years and over has the largest death rate, and it also sees the largest increase in death rate between 2000 and 2010 of over 300 per 100,000 population of all age groups. Although the cause of Alzheimer’s is multifactorial, old age is a key driver of disease development, and so could help explain the observed trend, which is a positive correlation between age and death rate from Alzheimer’s Disease. The source of the data appears to be reliable with no visible anomalies.
