What is the number of years it takes a specific population to double in size?
The time it will take for a population to double is based on numerous factors, not solely time.

In many cases, the combination of these factors will not lead to any growth at all (such as in a war-torn country with massive human flight or a stable country where the fertility rate is less than 2.0 and there is no immigration).
