Final answer:
When a population is experiencing little immigration and emigration, the population growth or decline is determined by the birth rate and death rate.
Step-by-step explanation:
When a population is experiencing little immigration and emigration, it means that there are very few individuals moving into or out of the population. In this scenario, the population growth or decline would depend mainly on the birth rate and death rate. If the death rate is higher than the birth rate, the population would decrease over time. Conversely, if the birth rate is higher than the death rate, the population would increase.
