If high birth rate and high out migration exist together how should actual growth be assessed?

Answer and explanation

Correct answer: Total effect should be seen after subtracting out-migration

Direct answer: Option B. Actual population growth is found by considering all population-changing components, not births alone. The basic relationship is: actual change = births − deaths + in-migration − out-migration. A high birth rate adds people, while out-migration removes people. For example, if births add 500 people and 700 people leave, the population may fall unless deaths and in-migration compensate for that loss. Option A is wrong because birth rate alone ignores people leaving and may exaggerate growth. Option B is correct because out-migration must be subtracted and the complete balance must be calculated. Option C is wrong because migration cannot be assumed to be zero without evidence. Option D is wrong because death rate measures deaths per population, whereas area measures land size. Memory cue: additions minus losses give the real change; out-migration is a loss.
