1. Data Collection: Collect data on the number of individuals and the number of deaths in each age interval. 2. Calculate qx: The probability of dying within each age interval is calculated as the number of deaths divided by the number of individuals at the start of the interval. 3. Calculate lx: Starting with a hypothetical cohort (e.g., 100,000 newborns), apply the probability of dying to estimate the number of survivors at the beginning of each subsequent interval. 4. Calculate dx: Determine the number of deaths in each interval by multiplying lx by qx. 5. Calculate Lx, Tx, and ex: These are derived from the lx and dx columns using specific formulas.
