Appendix VII: A ge-standardized prevalence estimates for smoking, 2006
Appendix VII provides age-standardized prevalence estimates for smoking for 145 countries. Prevalence data on smoking were collected from countries during the data collection phase of this report. Since these data were obtained from a broad range of surveys with different survey instruments and conducted in different years, the data were adjusted and then age-standardized to the WHO standard population to produce comparable prevalence estimates for 2006 for the four tobacco indicators of current and daily tobacco smoking and current and daily cigarette smoking. The age-standardization of data removes the differences attributable to demographic structures in countries. Due to this, agestandardized estimates must only be used to draw comparisons of prevalence estimates across countries at one point of time and within countries over time for time series data. Please refer to Technical Note II for more details on survey selection, the adjustments made and agestandardization.
