If a population has a growth rate of 2.5 percent how long will it take to double?

To calculate the doubling time of a population with a growth rate of 2.5 percent, you can use the Rule of 70. The Rule of 70 states that you divide 70 by the growth rate to determine the doubling time. In this case, 70 divided by 2.5 equals 28. Therefore, it would take approximately 28 years for the population to double with a growth rate of 2.5 percent.


Given a growth rate of 3 percent per year how long will it take for a population of 100000 individuals to double?

It will take approximately 23 years for a population to double with a growth rate of 3 percent per year. This can be calculated using the rule of 70, where you divide 70 by the growth rate to find the doubling time. In this case, 70 divided by 3 equals 23.33, which can be rounded to 23 years.


Took this entire time period for the population to double?

The time it takes for a population to double is known as the doubling time. It is calculated using the rule of 70, which states that you divide 70 by the growth rate to find the doubling time. For example, if a population is growing at a rate of 2% per year, it would take approximately 35 years for the population to double.

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. The fertility rate, food production rate, security (from foreign invasions and domestic violence or revolt), mortality rate, and numerous other elements are requisite to determine how long it will take a population to double in size. 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).
