How to fill out calculating population growth rate

How to fill out calculating population growth rate:

Start by collecting relevant data:

1. Gather information on the current population size, usually denoted as P0.
2. Determine the period of time for which you want to calculate the growth rate, denoted as t.

Calculate the final population size:

If you have data on the current population size (P0) and the annual growth rate (r), you can use the formula P(t) = P0 * (1 + r)^t to calculate the projected population size.

Determine the population growth rate:

1. The population growth rate (r) can be calculated using the formula r = (P(t) - P0) / P0 * t.
2. Substitute the values of P(t) and P0 into the formula to find the growth rate.

Interpret the growth rate:

1. A positive growth rate indicates population growth, while a negative growth rate suggests population decline.
2. The magnitude of the growth rate indicates the rate at which the population is increasing or decreasing.
