  12. 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 100 000) in 2003. Which parts of the UK were the healthiest and unhealthiest for heart disease? Describe two patterns shown by this data. Use your IT skills to draw bar charts to show this data for men and women. Select the area you live in. If the town you live in had a population of 50 000, how many men and women would have died of heart disease in 2003?

Respiratory diseases • Name one disease that showed a decrease from 1996 to 2004. • Name two diseases that showed an increase from 1996 to 2004. • What general pattern is shown by the totals for each year? • 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.
