MODEL ANSWER:

The given charts are the pictorial representations of the major accident causing factors among the Cox town residents and their accident statistics in three distinct years (1990, 2000 and 2010).

It is clear from the pie chart that a major proportion of accidents in Cox town are created either by mixing drinks with drive or by reckless driving. This collectively accounts for around 62% of the total causes of accidents. Approximately two-fifth of the accidents are related to the former, almost a quarter is the proportion of the latter. Almost a fifth of the accidents happen due to sleeplessness, which is almost double than that of thought diversion. Other factors such as poor condition of vehicles contribute an insignificant proportion of accidents.
As per the table, over these three years (1990, 2000 and 2010), when both the number of accidents and the number of cases reported surged, a declining trend can be seen in the number of casualties. The disparity between the number of accidents and cases registered between 1990 and 2010 was around 10,000, whereas this was only 233 in case of the number of casualties.

Overall, when drink and drive remained as the major cause of accidents in Cox town,the actual and reported accident numbers were inversely proportional to the number of casualties during the given years.
