The prevalence of smoking decreases with age after the 25-34 age group (25.5%) to 10.7% of those aged 60 years or over. This pattern is mirrored for males, but is relatively stable for females between the ages of 16 and 59, before falling to 9.6% of females aged 60 years or over.

Lung cancer incidence is highest for people aged 75 years and over, which may be expected due to the long time lags that can occur between smoking and the development of the disease.
