Historical Life Expectancy Interpretation

This grim historical arc—from a nine-year life expectancy in 1929 to today’s sixty-plus years—brutally charts how society’s progress in medicine and humanity has, more than anything, determined whether a person with Down syndrome gets a tragically short story or a full and flourishing life.

Modern Life Expectancy Interpretation

The global life expectancy for individuals with Down Syndrome has reached a robust average of 60 years, a testament to relentless medical progress, though national variations—like Norway's 66 years starkly contrasted with Israel's 59—remind us that geography, not just genetics, plays a pivotal role in defining longevity.
