Socioeconomic inequalities in smoking-attributable mortality in Europe; understanding trends 2000-2020 31 2 Comparing a wide range of European countries for a prolonged period of time is one of the strengths of this paper. Furthermore, the analyses presented in this paper rely on a unique set of data on mortality rates by country, age group, sex and educational group and include data on cause of death. Education has the benefit of being stable throughout the life course and has a strong link to behavioural factors such as smoking.50 However, as socioeconomic position is a complex construct, future research could investigate composite or multiple indicators of socioeconomic status simultaneously. Conclusion Overall, we can conclude that smoking-attributable mortality remains an important factor contributing to educational differences in life expectancy in Europe for both sexes. Among women, the peak in smoking-attributable mortality has not been reached yet in most countries, due to the time lag between smoking exposure and outcome. The good news is that low educated men in most countries are experiencing the greatest reductions in smoking-related mortality– the bad news is that educational gaps in mortality decline are emerging in mortality due to other causes of death. The need for tobacco control measures that decrease educational gaps remains high, especially for women.
