Quitter percentage by age

 

Bar chart showing quitter percentage among ever smokers, by age group, in 2020. Trends described in text. Data table below with 95% confidence intervals.

Quitter percentage varied significantly by age group,27 increasing dramatically with increasing age, as expected given that older smokers have had more time to become former smokers. In 2020, 40% of ever-smokers aged 20-24 were former smokers when surveyed, while three-quarters of ever-smokers aged 45 and older had quit (Figure 5.5).

The same pattern of increasing quitter percentage with age was observed in all years since 1999 (Figure 5.6). Between 1999 and 2020, quitter percentage appears to have generally increased among ever-smokers aged 20 and older. Among youth ever-smokers, quitter percentage was lower and more variable, appearing to decrease in the latest year with available data.
