Final answer:
In many countries around the world, a lower proportion of children and adolescents smoke cigarettes than is the case in North America.
Step-by-step explanation:
In many countries around the world, a lower proportion of children and adolescents smoke cigarettes than is the case in North America. This means that fewer children and adolescents smoke in other countries compared to North America.
For example, in Australia, there has been a significant decline in the number of people who smoke. In 1976, the proportion of men and women who smoked was 43% and 33% respectively. In 2014–15, it was 16.9% and 12.1%.
Therefore, the answer to the question is lower.
