OBJECTIVE: the study aims to estimate the differentials in life expectancy by income and work history in Italy during the 2000's, in order to evaluate the level of actuarial equity of the recent Italian retirement reform in computing benefits proportional to the contributions paid. DESIGN: retrospective cohort study. SETTING AND PARTICIPANTS: mortality follow up of a 1% sample of the Italian workforce employed or self employed in the private sector, retired between 1985 and 2003 (about 63,000 people), whose work history and income since 1985 is registered in the National Institute for Social Insurance (INPS) data base. MAIN OUTCOME MEASURE: mortality differentials computed through Cox model. RESULTS: social inequalities in survival in favour of the more advantaged categories of income and occupational classes are observed. CONCLUSION: the principle of actuarial equity assumes that life expectancy varies only according to age and birth cohort; nevertheless inequalities in life expectancy exist also along other dimensions, like income and occupational class: this means that the system is producing an opposite redistribution, from the careers more socially disadvantaged to the less disadvantaged ones.
