Abstract: Appropriate indexes and methods is the key for measurement and comparison of population longevity level across the world. This paper summarizes indexes for measuring population longevity level from dimensions including population age structure，deaths，and life table，and discusses the methodology on how to compare regional population longevity. The proportion of people aged 100 + in the total population，the proportion of people aged 80 + in the population aged 60 + ，and the proportion of people aged 100 + in the population aged 90 + are the representative indexes in the population age structure dimension，and the proportion of deaths occurring at age 90 + among the total deaths and the mean age at death are the representative indexes in the death population dimension，while in the dimension of life table，the chosen indexes are life expectancy at birth and at age 80. Based on these indexes，the single and multi-dimensional composite indexes can be constructed to compare the longevity levels among different regions. The result shows that Japan，France and Switzerland are the leading countries in longevity.
