How will the most scientific analysis of processes of population change be done?

Answer and explanation

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

Direct answer: Option B is correct. Population change is a multi-factor process, so a scientific analysis must use more than one indicator. Births and deaths show natural change; net migration shows the balance between people entering and leaving; age structure indicates the number of children, working-age people and older people; and social factors such as education, health, employment and family practices help explain why rates differ. Option A is incomplete because birth rate alone cannot show deaths or migration. Option C is wrong because area tells us about land size, not directly about demographic processes. Option D is also incomplete because the number of cities does not show the full population structure or movement. A careful study compares these indicators over time and across places. Memory cue: population analysis needs a dashboard of indicators, not one isolated number.
