Calculating Population Doubling Time
Which of the following correctly describes the procedure for calculating a population’s doubling time?
A
Determine the rate of natural increase, then apply the formula 70 divided by the RNI to find the doubling time in years.
B
Divide the population by the rate of natural increase, then multiply by 70 to calculate the doubling time.
C
Add the RNI to 70 and then divide the total population by this sum to determine the doubling time.
D
Multiply the RNI by 70, then subtract this value from the current population to estimate doubling time.
