FAQs on Age Pyramids Video Lecture - Biology for ACT
| 1. What is an age pyramid? |  |
Ans. An age pyramid is a graphical representation of the age and sex distribution of a population. It shows the number or percentage of people in different age groups, typically divided by gender, at a specific point in time.
| 2. How is an age pyramid useful in understanding population trends? | |
Ans. An age pyramid provides valuable insights into population trends by showing the relative size of different age groups. It helps identify whether a population is growing, stable, or declining. By examining the shape of the pyramid, one can understand factors such as birth rates, mortality rates, and life expectancy within a population.
| 3. What does a broader base in an age pyramid indicate? | |
Ans. A broader base in an age pyramid indicates a higher proportion of younger individuals in the population. This suggests a higher birth rate and a growing population. It can also reflect factors such as improved healthcare and reduced infant mortality rates.
| 4. How does an age pyramid change over time? | |
Ans. Age pyramids change over time due to various demographic factors. In developing countries, as healthcare improves and living conditions get better, the pyramid may transition from having a wide base to a more even distribution across age groups. In developed countries, with lower birth rates and longer life expectancy, the pyramid may start to show a narrower base and an increasing number of older individuals.
| 5. What can an inverted age pyramid indicate? | |
Ans. An inverted age pyramid, where the older age groups have a higher proportion of the population compared to the younger age groups, indicates a declining population. This could be due to factors such as low birth rates, high emigration, or an aging population with lower fertility rates. It highlights the need for policies to address population decline and support an aging society.
