Smoking prevalence by age

 Canadian Tobacco, Alcohol and Drugs Survey, 2015.See data tables with 95% confidence intervals below.

In 2015, smoking varied significantly by age group:11 prevalence was highest among young adults aged 20-24 and lowest among youth aged 15-19 (Figure 1.6).

A general pattern of decreasing prevalence after early adulthood appears to have held for most survey years between 1999 and 2015 (Figure 1.7).  During this time, prevalence decreased overall in every age group, although the steepest decline was observed in the youngest group, 15- to 19-year-olds. Declines were less marked among older age groups, and there has been little net change observed in the last decade among those aged 55 and older.

When examining differences between age groups and over time using repeat cross-sectional data such as this, consider that some of the differences between age groups could also be due to cohort effects (as well as age effects), in addition to changes over time.
