Steps to Calculate a Life Table:

Here are the steps to calculate a life table:

1. Collect Data:
   Gather mortality data for a specific population over a given period.
2. Determine Age-Specific Death Rates:
   Calculate the number of deaths in each age group.

Life Table Calculation Example

Let’s make it more understandable with an example.

Step 1: Collect Data

Consider we have the following mortality data for a small population over one year:

• Age 0-1: 5 deaths out of 100 births
• Age 1-2: 2 deaths out of 95 survivors
• Age 2-3: 1 death out of 93 survivors

Step 2: Determine Age-Specific Death Rates

• Age 0-1: 5/100 = 0.05
• Age 1-2: 2/95 = 0.021
• Age 2-3: 1/93 = 0.011

Step 3: Calculate Probabilities

• Age 0-1: Probability of dying = 0.05
• Age 1-2: Probability of dying = 0.021
• Age 2-3: Probability of dying = 0.011

Step 4: Create the Life Table

This table shows the survival rate for each age group, giving a clear picture of mortality and survival.
