They are both a cause and a consequence of unequal opportunities, and they have far-reaching consequences at both the individual and the societal level. For instance, they are a serious concern for the equitable design of pension policies, as individuals with high socioeconomic status spend more time in retirement and receive pensions for a longer time.1
Inequalities in life expectancy by education have long been a focus of epidemiological and demographic research, as education is comparatively straightforward to measure, it is fixed from early adulthood and precedes other markers of attained socioeconomic status such as income or wealth, and it is a strong predictor of the overall socioeconomic status.2 Trends in educational inequalities in mortality are heterogeneous across countries. The gap between the lowest and highest educated has increased in some countries and decreased in others.3
The paper by Zazueta-Borboa et al4 provides an important contribution to our understanding of these changing inequalities. Using high-quality register data from three European countries (England/Wales, Finland and Italy represented with data from Turin), it assesses long-term trends in the …
