If birth rate falls and death rate also falls, what should be checked to understand growth?

Answer and explanation

Correct answer: Difference between both rates

Direct answer: A, the difference between the two rates. Population growth is not decided by looking at the birth rate or death rate alone. Natural increase is found by comparing the birth rate with the death rate: birth rate minus death rate. If both rates fall by the same amount, their gap may remain unchanged; if the death rate falls more than the birth rate, the gap may widen and growth may be higher. Option A is correct because the difference shows the balance between additions and losses through natural change. B is unrelated to this calculation. C does not measure demographic change. D is only a label and gives no numerical information. Memory cue: natural growth = birth rate − death rate.
