The source of the data is the "National Health Administration's Survey on Smoking Behavior of the People." The survey collects information on people's smoking habits through telephone interviews. For more information, please refer to the "Tobacco Harm Prevention Information Website" of the National Health Administration (http://tobacco.hpa.gov.tw/).The definition of "household secondhand smoke exposure rate" is the ratio of people who have been exposed to others smoking in front of them at home in the past week. The calculation formula is number of respondents aged 18 and above who answered "there are others smoking in front of them at home in the past week" / number of valid completed samples of people aged 18 and above * 100%.
