How do births affect population change?

Answer and explanation

Correct answer: By adding new individuals to the population

Direct answer: Option C is correct. A birth means that a new person is added to the people living in an area. Therefore, if deaths and migration are not considered, more births increase the population. Step by step: first, a baby is born; second, that baby becomes a new member counted in the population; third, the total number rises by one. Option A is wrong because births do not remove people; deaths or out-migration can reduce population. Option B is wrong because a birth itself adds a person, although the total population could remain unchanged if an equal number of people die or leave. Option D is wrong because birth does not change the physical area of a region. Memory cue: birth means “addition”; death means “subtraction.”
