To calculate the mean annual change, you would typically follow these steps:
1. Determine the initial value and final value of the variable you are analyzing over a specific time period.
2. Subtract the initial value from the final value to find the total change.
3. Divide the total change by the number of years in the time period to find the average annual change.
The formula for calculating the mean annual change is:
Mean Annual Change = (Final Value - Initial Value) / Number of Years
This calculation will give you the average rate of change per year over the specified time period.
