If immigration and emigration are equal in an area, what will be the effect of migration on total population?

Answer and explanation

Correct answer: Net change due to migration will be low or zero

Correct answer: A. Immigration means people enter an area, while emigration means people leave it. Net migration is calculated as immigration minus emigration. If the numbers entering and leaving are equal, the difference is zero, so migration itself causes no net increase or decrease in the area’s population. The total population can still change because births and deaths may not be equal. B is wrong because equal inflow and outflow do not automatically double population. C is wrong because migration does not end the biological event of birth. D is wrong because migration cannot make the death rate infinite. A memory cue is: equal in and out means balance; count the difference, not the movement on each side.
