the number of individuals exiting the population

all of the above

the number of deaths

Answer 1

The size of a population is affected by all of the above factors. Specifically:

• The number of births contributes to increasing the population size.
• The number of individuals entering the population (through immigration) also increases the population size.
• The number of individuals exiting the population (through emigration) decreases the population size.
• The number of deaths leads to a decrease in the population size.

Thus, all of these factors play a role in determining the overall size of a population.
