Plus vous irez à l’école, plus vous vivrez longtemps

Une étude récente, présentée sur VoxEU, s’intéresse aux différences de longévité entre les individus et montre que l’éducation est le facteur explicatif le plus fort.

"These large increases happened during a time period when there was a sizeable increase in income and wealth inequality. Although we do not want to make any causal statement, it is hard to avoid thinking that the increase in income inequality lurks behind the increase in the socioeconomic gradient of longevity. If so, we should conclude that the upsurge of income inequality in the recent decades has had welfare implications much stronger than previously thought. Our results also show, however, that education seems to matter more than wealth. Therefore, it might very well be that the increase in the socioeconomic gradient of longevity is also tightly related to selection: over the years, the pool of less educated or unmarried people has become worse off in terms of their ability to survive."
