Exercise 8

Calculate the age-group specific YPLL for both white and black males. In what age group is the YPLL greatest?

Step 1 of 6

YPLL (Years of potential life cost) can be defined as the scale of evaluating the relative effect of health associated events on a population. It is used to index the misplacement of anticipated years of life, due to untimely death in the population. For age-specific data, it is calculated by the following formula:

Endpoint is a predetermined value, and taken as 65 years. It is regarded as the average life expectancy of the population. Age group midpoint is calculated, by using the following formula:
