Heart Disease The UK has one of the highest death rates for heart disease in the world. Look at the data below, which shows death rate from heart disease (per ) in Which parts of the UK were the healthiest and unhealthiest for heart disease? Describe two patterns shown by this data.

Suggest an explanation for this pattern, remembering that there has been a great decrease in people employed in industries such as coal mining and in the absence of asbestos, as well as improved health and safety laws. What do you expect to happen to these figures in the next 10 years? Explain your answer.
