Abstract :This article explores the demographic landscape of Türkiye from 1920 to 2020 using life tables, focusing on adult mortality trends and employing the modal age at death as a key metric. It emphasizes the shifts in mortality patterns, particularly in relation to life expectancy, and addresses the historical and contextual factors influencing Türkiye’s demographic transition. The literature review underlines the significance of the modal age at death as an indicator for assessing mortality dynamics, offering insights into compression and delay in mortality. The study utilizes a comprehensive methodology, including the acquisition of infant mortality rates, life table construction, and the calculation of modal age at death and standard deviation. The results highlight a remarkable increase in life expectancy over the century, driven by improvements in healthcare and reductions in infant and child mortality. The analysis of the modal age at death reveals trends of mortality delay and compression, with the decline in the standard deviation calculated for the modal age at death indicating a gradual shift of mortality to older ages. The findings align with Türkiye’s demographic transition stages, emphasizing the evolving health landscape and the importance of considering modal age at death alongside life expectancy for a nuanced understanding of the trends of adult mortality. This study bridges a significant gap in the existing research on Türkiye by utilizing the modal age at death to assess older age mortality trends.
