Which is the correct formula for total population change?

Answer and explanation

Correct answer: Change = Births − Deaths + Net Migration

The correct answer is A: total population change = births − deaths + net migration. Begin with natural change: births add people to the population, while deaths remove people, so natural increase is births minus deaths. Then include migration. Net migration is the number entering minus the number leaving, so it may be positive or negative. The complete formula combines both sources of change: natural increase plus net migration. Option A is correct because it includes births, deaths, and the migration balance in their proper roles. Option B describes weather or climate elements, not population accounting. Option C compares physical features and cannot count people. Option D is an invented relationship with no demographic meaning. A negative net migration must be added with its negative sign, which reduces the total change. For example, births of 100, deaths of 60, and net migration of −10 give 100 − 60 − 10 = 30. Memory cue: people are added by births and arrivals, and removed by deaths and departures.
