If the birth rate falls but the death rate falls even faster, what should be examined in growth analysis?

Answer and explanation

Correct answer: The gap between the birth rate and the death rate

Direct answer: A is correct. Natural increase is determined by the difference between the birth rate and the death rate. Suppose the birth rate falls from 30 to 24 per thousand, while the death rate falls from 15 to 8 per thousand. The birth rate is lower than before, but the gap changes from 15 to 16 per thousand, so natural increase can become slightly larger. The exact figures are not given in the question, so the correct method is to examine the gap. B is wrong because the birth rate alone cannot show natural increase. C is wrong because area does not calculate the difference between births and deaths. D is unrelated to this population-growth calculation. Memory cue: natural increase depends on birth rate minus death rate, not on either rate alone.
