How To Calculate Doubling Time Of Population

What is Doubling Time and How is it Calculated?

https://populationeducation.org/what-doubling-time-and-how-it-calculated/

Doubling time is the amount of time it takes for a given quantity to double in size or value at a constant growth rate. We can find the doubling time for a population undergoing exponential growth by using the Rule of 70. To do this, we divide 70 by the …

Rule of 70 to approximate population doubling time
