Death Calculator

What assumptions are built into estimations of life expectation? This animation calculates a life expectancy based on information used by insurance companies. Data is collected on the number of people dying in each age class (year of age) for a particular year. This pattern is assumed to continue unchanged into the future. To calculate the average of life expectancy for a given age, the average age of all the people dying that are older than that age is calculated. For example, to calculate the average life expectancy of an 18 year old male you would calculate the average age of all males over the age of 18 dying in that year. This is a technique that can provide useful information. However the assumption that the pattern of mortality will not change over time is clearly false. Life expectancy of people in western nations has been increasing most of the time over the last several centuries.
