Death Probabilities

Annual Trustees Reports provide estimates describing the actuarial status of Social Security's Old-Age and Survivors Insurance (OASI) and Disability Insurance (DI) Trust Funds under current law. In making these estimates, the Trustees make key demographic assumptions and economic assumptions. The intermediate set of assumptions reflects the Trustees’ best estimates of future experience.

The following tables provide historical and projected probabilities of death by single year of age, gender, and year. In this context, a given probability of death represents the chance that someone exactly the given age will die within one year. Actuarial Study Number 120 provides additional information about this and other mortality concepts.
