This study examines inequalities in life expectancy by educational status, age-standardised mortality rates, and age-at-death, using high-quality linked and supplementary unlinked data from 25 OECD countries in 2013-19. Absolute gaps in life expectancy at age 25 between high and low education groups are on average equal to 5.2 years and 8.2 years for women and men, respectively. Deaths of despair among women and men aged 25-64 contribute on average 7% and 11% to the total gap in life expectancy between high and low education groups, respectively. Comparing identical country-sources to the previous analysis, absolute gaps in life expectancy at age 25 have increased by 0.5 year and 0.4 year on average for women and men between 2011 and 2016.
