What is the formula of actual growth of population?
Answers
Answer:
The annual percentage growth rate is simply the percent growth divided by N, the number of years. In 1980, the population in Lane County was 250,000.
Answer:
The standard formula for calculating growth rate is:
Gr= N / t
Here, Gr is the growth rate expressed as a number of individuals. N is the total change in population size for the entire time period, also expressed as a number of individuals. t is time, usually expressed in number of years. Of course, for really quickly growing populations, it might also be expressed in months or some other unit of time. The formula is calculated the same way regardless of the unit of time used.
In order to calculate the overall growth rate, you first have to figure out N. This is done by subtracting the initial population (or P1) from the current population, or the population at the end of the time period you are using (or P2). Therefore:
N= P2 - P1
Now, let's take a look at few examples that put this formula into practice.
