So if I want to calculate life expectancy for 2022, I would
- create a newborn cohort (excact size doesn't matter here I suppose)
- calculate the risk of death for each age group, using "deaths per capita in 2022"
- then I just go through the risk array, remove a proportion of individuals from the cohort each year (risk=proportion removed?) until they're all gone.
- for each age I use the number of individuals that were removed as my weight for the respective age

- add all elements (weights applied) up
- divide by the sum of all weights
Right? I always wanted to know how this works.
