Abstract: Monitoring the changes in mortality patterns and levels requires studying mortality models and measures of lifespan length and variation. Measures of lifespan length and variation can be obtained from life tables or from mortality modes. In this paper, measures of lifespan length and variation are presented for mixture model introduced by Zanotto, L., V. Canudas-Romo, and S. Mazzuco. 2021. “A Mixture-Function Mortality Model: Illustration of the Evolution of Premature Mortality.” European Journal of Population 37 (1): 1–27. This was applied to the case of Egypt for males and females in the period 1950–2021. The mixture model was able to fit Egypt’s mortality pattern well for both males and females. The calculated measures of lifespan length and variation show that there is an increasing longevity and a declining variation of age at death distribution across time for both males and females.
