Life expectancy calculation
- ex = Tx/lx
- Tx is the total number of person-years lived by the cohort from age x until all members of the cohort have died (look back at previous slide)
- That is sum(nLx) from the row for age x to the last row in the table
- For the exercise, Tx = 2,370,099 and lx = 89,867. So, ex = 26.4 years
