II. Survival situation in the life table
In the abridged life tables for 2009, the number of survivors at age 65 is 86,742 for males and 93,599 for females in a stationary population supported by 100,000 annual live births. These facts lead that the survival ratio until age 65 is 86.7% for males and 93.6% for females. In the same way, it follows that the survival ratio until age 75 is 71.9% for males and 86.5% for females, and the survival ratio until age 90 is 22.2% for males and 46.4% for females.
The number of stationary population from age 0 (total person-years from age 0) is 7,958,862 for males and 8,644,266 for females. The number of stationary population from age 65 (total person-years from age 65) is 1,637,970(20.6%) for males and 2,243,592(26.0%) for females.
The median length of life, which means the age when exactly half of the cohort remains alive, is 82.55 years for males and 89.20 years for females.
