As fertility rates decline, one major societal impact is an increase in the ________ of the population, leading to significant changes in economic and healthcare systems.

As fertility rates decline, one major societal impact is an increase in the average age of the population. This means there are more older people compared to younger people. For example, if fewer babies are born, there will be a larger group of seniors who need support and care. This shift can lead to changes in economic systems, as there may be fewer workers to support the economy and more demand for healthcare services for the elderly. Overall, as the population ages, governments and communities must adapt to meet the needs of an older generation.
