II. Survival situation in the life table
In the abridged life tables for 2006, the number of survivors at age 65 is 86,135 for males and 93,260 for females in a stationary population supported by 100,000 annual live births. These facts lead that the survival ratio until age 65 is 86.1% for males and 93.3% for females. In the same way, it follows that the survival ratio until age 75 is 70.3% for males and 85.5% for females, and the survival ratio until age 90 is 20.6% for males and 43.9% for females
The number of stationary population from age 0 (total person-years from age 0) is 7,899,801 for males and 8,580,687 for females. The number of stationary population from age 65 (total person-years from age 65) is 1,588,856(20.1%) for males and 2,186,233(25.5%) for females.
The median length of life, which means the age when exactly half of the cohort remains alive, is 81.94years for males and 88.61 years for females.
