Which of the following is an implication of a declining fertility rate in a country?

A declining fertility rate in a country typically leads to an aging population, as fewer children are being born in relation to the demographic of older individuals. This shift means there will be fewer workers to support the larger pension-using segment of the population. As a result, there is increased pressure on pension systems because there will be fewer contributors to fund pensions for a growing number of retirees. This can lead to financial strain on government programs and social safety nets responsible for supporting the elderly.

The other implications associated with declining fertility rates include a smaller young workforce and an overall decrease in the youth demographic, leading to a more aged population rather than a youthful one. Consequently, this can lead to lower overall population growth or even population decline, as the birth rates fall further below replacement levels.
