Deduce the formula that represents the population growth rate.

• Population growth rate = (birth - death) + (immigration + emigration)

• Population growth rate = (death + emigration) - (birth + immigration)

• Population growth rate = (death + emigration) - (birth - immigration)

• Population growth rate = (birth + immigration) - (death + emigration)

Answer explanation

The correct formula for population growth rate is (birth + immigration) - (death + emigration), as it considers the increase from births and immigration while subtracting the decrease from deaths and emigration.
