Canadian Tobacco Use Monitoring Survey, 2009: Annual, Person File

This survey tracks changes in smoking status, especially for populations most at risk such as the 15- to 24-year-olds. It allows Health Canada to estimate smoking prevalence for the 15- to 24-year-old and the 25-and-older groups by province and by gender on a semi-annual basis.本追踪调查旨在监测吸烟状态的动态变化，尤其聚焦于15至24岁这类吸烟高风险人群。借此，加拿大卫生部（Health Canada）可按省份与性别维度，以半年为统计周期，分别估算15至24岁及25岁以上人群的吸烟流行率。
