  2. Life expectancy - Wikipedia

    en.wikipedia.org/wiki/Life_expectancy

    For example, if 10% of a group of people alive at their 90th birthday die before their 91st birthday, the age-specific death probability at 90 would be 10%. This probability describes the likelihood of dying at that age, and is not the rate at which people of that age die. [c] It can be shown that

  6. Mortality rate - Wikipedia

    en.wikipedia.org/wiki/Mortality_rate

    The crude death rate is defined as "the mortality rate from all causes of death for a population," calculated as the "total number of deaths during a given time interval" divided by the "mid-interval population", per 1,000 or 100,000; for instance, the population of the United States was around 290,810,000 in 2003, and in that year, approximately 2,419,900 deaths occurred in total, giving a ...

  9. Gompertz–Makeham law of mortality - Wikipedia

    en.wikipedia.org/wiki/Gompertz–Makeham_law_of...

    The Gompertz–Makeham law of mortality describes the age dynamics of human mortality rather accurately in the age window from about 30 to 80 years of age. At more advanced ages, some studies have found that death rates increase more slowly – a phenomenon known as the late-life mortality deceleration [2] – but more recent studies disagree. [4]
