How do births affect population?

Answer and explanation

Correct answer: They increase population

The direct answer is B: births increase population. Population is the total number of people living in a place. When a baby is born, one new person is added to that population, so the number rises if deaths and migration are not being considered at the same moment. Births are therefore an adding process in demographic change. Option A is wrong because births do not remove people; deaths or movement out of the area can reduce the number. Option B is correct because a new member enters the population. Option C is wrong because birth does not change the physical area of a region. Option D is wrong because rivers are natural water features and are not created by human births. Memory cue: birth means add one; death means subtract one.
