The information source is the "National Health Survey on Smoking Behavior" of the Health Promotion Administration. The survey uses telephone interviews to collect relevant information on people's smoking habits, and a brief introduction can be found on the Health Promotion Administration's "Tobacco Hazard Prevention Information Website" (http://tobacco.hpa.gov.tw/).The definition of "Secondhand Smoke in Smoke-Free Public Places" is the percentage of people who have smoked in front of others in smoke-free public places as defined by the Tobacco Hazard Prevention Act in the past week. The calculation formula is: the number of respondents aged 18 and above who answered "there were people smoking in front of them in smoke-free public places as defined by the Tobacco Hazard Prevention Act in the past week" / the number of valid completed interviews of respondents aged 18 and above * 100%.
