Smoking prevalence by age

 Canadian Tobacco, Alcohol and Drugs Survey,2013.See data tables with 95% confidence intervals below.In 2013, smoking varied significantly by age group:11 prevalence was highest among young adults aged 25-34 and 20-24 (Figure 1.6). The lowest observed prevalence was among youth aged 15-19 and adults age 55 and older.

A general pattern of decreasing prevalence after early adulthood appears to have held for most survey years between 1999 and 2013 (Figure 1.7). Although prevalence decreased overall in all age groups during this time, the largest drop was observed in the youngest age group, 15- to 19-year-olds. This decline was less marked among older age groups, and little net change has been observed in the last decade among those aged 55 and over.

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.
