On what basis will the most reliable exam analysis of processes of population change be made?

Answer and explanation

Correct answer: By studying births, deaths, net migration, age structure and social factors together

Answer: A. Population change is a demographic process, so it cannot be understood from one number alone. Begin with natural change: births minus deaths. Then add net migration, which is immigration minus emigration. Age structure shows whether children, working-age people, or older people form the larger share, while social factors such as education, health, marriage patterns, and employment can influence demographic behaviour. Therefore, a reliable exam analysis combines all these related indicators. Option B is incomplete because birth rate alone ignores deaths and migration. Option C gives only a definition and does not analyse an actual process. Option D concerns area and density, but density describes how people are spread, not all causes of population change. Memory cue: change means births minus deaths plus net migration; structure explains who the people are.
