They come in three types—rapid growth, slow growth, and negative growth—and are essential for understanding demographic challenges and planning for economic sustainability. Therefore, the correct answer is c.
Step-by-step explanation:
Population pyramids are graphical representations that show the age and sex distribution of a country's population and, as such, they provide insights into a country's age distribution and future population trends. The correct option that explains the importance of population pyramids is c) Population pyramids offer insights into a country's age distribution and future population trends.
Population pyramids help us understand different aspects of a society such as social stability, economic development, and demographic statistics like birth rates and death rates. They come in three types: rapid growth, slow growth, and negative growth. A broad base in a pyramid indicates a young population with high birth rates, common in countries at earlier stages of economic development, while a narrower base suggests an aging population with lower birth rates, typical of more urbanized and industrialized societies.
The shape of the population pyramid can also indicate the ratio of dependents to working-age population, potential challenges for healthcare and pension systems, and the need for adequate policies to support economic sustainability as the population evolves. By analyzing these graphical tools, we can predict potential challenges and plan for them effectively.
