Paper

Abstract

We examined trends in life expectancy at birth, modal age at death, and lifespan variation in South Korea from 1970 to 2023, and evaluated hypotheses regarding mortality compression and shifting in relation to increases in life expectancy at birth.

Research summary

The paper examines trends in life expectancy and lifespan variation in South Korea, suggesting that mortality compression and shifting are related to increases in life expectancy. This research is relevant as it addresses population-level changes in longevity and mortality, which are critical for understanding aging dynamics.
