II. Survivorship in the life tables
In the abridged life tables 2010, the number of survivors at age 65 was 86,929 for males and 93,592 for females of the original hypothetical cohort of 100,000 infants. These mean that the survival rate until age 65 is 86.9% for males and 93.6% for females. In the same way, it follows that the survival rate until age 75 is 72.1% for males and 86.5% for females, and the survival rate until age 90 is 22.0% for males and 46.1% for females.
The stationary population from age 0 (total person-years supported by 100,000 annual live births) was 7,963,518 for males and 8,638,891 for females. The stationary population from age 65 was 1,639,074 (20.6%) for males and 2,236,330 (25.9%) for females.
The median length of life, which means the age when exactly half of the cohort remain alive, was 82.63 years for males and 89.15 years for females.
