This contribution proposes a measure of retirees' pension wealth in the French public Pay-As-You-Go schemes (first and second pillar schemes) and of its distribution among the population of retirees in 2012 using the Echantillon Inter régimes de Retraités (EIR) panel data. We show that aggregate pension wealth amounts to around €5 800 billion assuming a 2 percent discount rate which represents 25 years of benefits and 2.8 years of 2012 GDP. There are significant differences in the amount of individual's pension wealth between the pension schemes of the private and public sectors, and between men and women. Moreover, there is more inequality in the distribution of pension wealth among private sector retirees than public sector ones. Codes JEL : G23, H31, J32. We thank the Direction de la recherche, des études, de l'évaluation et des statistiques of the French Government for providing us with the EIR 2012.
