This article analyses the development of inequalities across the lifespan and generations in France using a pseudo-panel developed from successive waves of the French Household Expenditure Survey that took place between 1979 and 2011. The standard of living of individuals, evaluated using individualised disposable income or private consumption, including housing costs, is decomposed by sex and educational attainment. Our Age-Period-Cohort models reveal that men with lower education levels who were born after 1950 experienced a significant decline in disposable income compared to those born between 1918 and 1950. Conversely, we observe no decline in disposable income when the whole population of men is considered. The evolution is rather different for women: those with lower education levels did not experience any decline, whereas the overall population of women benefitted from a strong increase in disposable income across generations.
