Data sources and processing
All smoking data presented in this report are for current (not daily) smoking of all tobacco products. The snapshot for current smoking in 2021 is a linear estimate calculated using 2020 and 2025 data from trend projections published by the WHO.45
For Hong Kong, the snapshot for 2021 is a linear estimate based on 2016, 2018, and 2020 source data from the Thematic Household Survey Reports No. 5946, 6447 and 70.48
For Vietnam, the 2021 projection was calculated in the same way using the 201049 and 201650 Vietnamese GATS reports.
Similarly, we use a term of current (not daily) vaping. Figures from China, Hong Kong, Japan, Malaysia and the Philippines are from surveys conducted around 2018 and are projected to 2021.
From other countries – where surveys have not been conducted – figures are from GSTHR Global Number of Vapers Estimation51 and are also projected to 2021. Projections were calculated based on the Statista Market Revenue Forecast52 and the United Nation World Population Prospects.53
In the GSTHR Burning Issues report, the number of smokers was calculated using point estimates of smoking prevalence for 2018, and population data for adults (15+) for 2018. In this report, the number of smokers was calculated using projections of smoking prevalence for 2021, and population data for adults (15)+ for 2021.
