Young-Old Threshold

How it works

Comparisons

Highlighted claims

• Mortality decline below the young-old threshold decreases lifespan inequality, while mortality decline above it increases lifespan inequality. — Divergence in age-patterns of mortality change drives international divergence in lifespan inequality
• Mortality changes near the threshold have little effect on the variance in age at death. — Divergence in age-patterns of mortality change drives international divergence in lifespan inequality
• The young-old threshold is always below the mean age at death after the index age. — Divergence in age-patterns of mortality change drives international divergence in lifespan inequality
• The threshold advances as life expectancy rises, modal age at death increases, and mortality becomes more compressed. — Divergence in age-patterns of mortality change drives international divergence in lifespan inequality
• Under modern mortality, the threshold is approximately 1.5 standard deviations below the adult modal age at death and about one standard deviation below life expectancy. — Divergence in age-patterns of mortality change drives international divergence in lifespan inequality
