Out now in JIM 📣 Longer lives are one of humanity's great achievements, not a crisis. If we define old age by remaining life expectancy rather than a fixed 65, the EU old-age dependency ratio stays around 20% instead of climbing to 40%. In the paper, we offer a more positive lens on ageing 🧘

Low-educated groups die at higher rates from nearly every cause, yet the share of deaths from each cause is almost the same as in high-educated groups. So the common idea that they die mostly of "avoidable" diseases doesn't quite hold. Denmark and the US both 🇩🇰🇺🇸 Open Access 👇

[Paper alert] Mortality decreases for highest socioeconomic groups in Denmark 🇩🇰 while stagnating for lowest ones | Survival to retirement | Danish registry | @cosmostrozza.bsky.social in @genus.bsky.social with @svigezzi.bsky.social @juliacalla.bsky.social @sandrsalek.bsky.social @ikashnitsky.phd

link.springer.comSocioeconomic inequalities in survival to retirement age in Denmark: a register-based analysis - GenusAround the world, people are increasingly living to older ages. This challenges the sustainability of the pension systems. In Denmark, statutory retirement age increases gradually to account for changes in life expectancy. However, the chances of reaching retirement age are not equal across the Danish population, and raising the retirement age could disproportionally impact those of lower socioeconomic status. In this study, we investigated socioeconomic inequalities in mortality before reaching retirement age in Denmark and how a higher retirement age would affect survival to retirement across socioeconomic groups. We used Danish registry data over a 30-year period, focusing on 19 consecutive birth cohorts: 1936–1954. We assessed the probability of dying between age 50 and retirement age, set at 65 and 67, across socioeconomic groups using three dimensions of socioeconomic status: education, occupation, and income. We found that the gap in survival has widened over time between the lowest and highest socioeconomic groups for each indicator, driven mostly by limited or stagnant improvements in the lowest socioeconomic groups. Our findings show that raising the retirement age from 65 to 67 disproportionately affects individuals from lower socioeconomic groups, especially men, in absolute terms. Pension reforms that link retirement age to life expectancy are sharpening inequalities, as lower-SES groups are not only facing higher early mortality, but also experience much slower improvements in mortality.

🇩🇰 Denmark is proud about its low inequality (and rightfully so! few countries do better) Yet, in current Danish society, the richest quarter of males have a 5% risk of not surviving in the age period 50-65; for the poorest quarter of males this figure is… 22%🤯 And this gap is increasing 🤨

A major finding is that across 19 cohorts of retirees, consistently almost 1 in 4 low-income men do not survive between age 50 and retirement while high-income men's survival improved dramatically from 1 in 10 to 1 in 20 as shown in the figure below (panel c) 👀

Single people living alone face higher mortality and age at death variation before 65, regardless of their education. The mortality gap with other sub-populations widened across Danish cohorts 1936-1954, and would be even larger if retirement age was 67/70 🇩🇰☠️
