The figure given provides information regarding the habits of smoking of UK inhabitants by age (16-74). In general, it is clear that younger people, from sixteen to forty-four years old, are light smokers, while the old ones (45 to 74 years old) are mostly ex-smokers. However, the percentage shows that the majority of UK people are never smoke.
As can be seen, the highest proportion of heavy smokers are those who are 35 to 54 years old, which is more than 20%. In contrast, less than 5% of adults (16-24) and the elderly (65-74) are heavy smokers. Moreover, just under 60% of younger citizens from 16 to 34 years old prefer to be a light smoker and slightly above 10% has decided to leave their smoking habits.
In addition, as they get older, people in the UK have a tendency to quit smoke. It is evidenced by the highest proportion of the ex-smokers in the ageing population (55-74 years old), which is above 60 per cent.
