Life Expectancy Data Discrepancies Between CDC and SSA Raise Planning Concerns
What happened
Discrepancies exist between the life expectancy data published by the Centers for Disease Control and Prevention and that used by the Social Security Administration. While the CDC reported that life expectancy at birth reached 79.0 years in 2024, this figure is a combined average across the entire population. In contrast, SSA cohort estimates project that a child born in 2024 will live to 84.2 years.

Why it matters
These differing data types create a life expectancy gap that complicates long-term financial planning. Traditional retirement planning often relies on static assumptions about longevity, and the contrast between national averages and cohort-specific estimates highlights this challenge for individuals and society.
