If both birth rate and death rate decline but birth rate is still higher than death rate, what will happen?

Answer and explanation

Correct answer: Population will keep growing but pace may change

Answer: A, the population will keep growing, although the speed of growth may change. Natural increase is calculated by comparing births with deaths: natural increase = birth rate − death rate. If the birth rate remains higher than the death rate, this difference is positive. Therefore, more people are added through births than are removed through deaths. The fact that both rates are falling does not by itself mean that population will decline; the relationship between the two rates is important. A is correct because growth remains positive, though a smaller gap can make it slower. B is wrong because population immediately declines only when deaths are greater than births, ignoring migration. C is wrong because natural growth ends only when the two rates become equal or the balance is otherwise zero. D is wrong because migration is a separate movement of people and does not become impossible merely because birth and death rates change. Memory cue: compare the two rates, not just whether each one is rising or falling.
