What is the most accurate meaning of population momentum?

Answer and explanation

Correct answer: Growth continuing for some time due to previous age structure

Direct answer: A is correct. Population momentum is the tendency of population growth to continue for some time because of the age structure created in earlier years. If a population previously had many children and young adults, many people may later enter reproductive ages. Consequently, births can remain substantial even after fertility or birth rates begin to decline. A is correct because it describes this delayed effect of past age composition on future growth. B is wrong because it refers to the movement of water, not demography. C is wrong because momentum does not mean that deaths become zero. D is wrong because density and area are different geographical measures. The term “momentum” is a memory clue: like a moving object that does not stop instantly, population growth may not stop immediately when birth rates fall.
