What is the natural reason for new people being added to a population?

Answer and explanation

Correct answer: Births

Correct answer: A, births. In population studies, births add new individuals to the population through a natural demographic process. The natural increase of a population is commonly understood by comparing births with deaths: natural increase equals births minus deaths. Option A is correct because a birth creates a new member of the population. Option B is wrong because deaths remove people and reduce population size. Option C, immigration, means people move into an area from another place; it can increase the population, but it is a migration process rather than a natural increase process. Option D, emigration, means people move out of an area and usually reduces its population. The question uses “natural reason,” so distinguish births and deaths from movement between places. Memory cue: natural change = births minus deaths; migration change = immigration minus emigration.
