Age Pyramid and Population Decline
An age pyramid is a graphical representation of the age and gender structure of a population. It is a tool used by demographers to study the demographic characteristics of a population. An age pyramid can be used to show the population's age distribution, birth rate, death rate, and life expectancy.
Declining Population
A declining population is a situation where the number of deaths exceeds the number of births in a population. This can occur due to various reasons such as low birth rates, high death rates, emigration, or a combination of these factors. A declining population can have significant social, economic and political consequences.
Urn-shaped Age Pyramid
An urn-shaped age pyramid is a graphical representation of a population with a declining population. It is called urn-shaped because of its resemblance to an urn or vase with a narrow base and a wide top. The urn-shaped age pyramid has a smaller number of children at the base, a larger number of adults in the middle, and a smaller number of elderly people at the top.
Explanation
The urn-shaped age pyramid is a sign of a declining population because there are fewer children being born than in the past, resulting in a smaller base of the pyramid. This, in turn, leads to a smaller number of people in the reproductive age group, resulting in even fewer children being born. As a result, the population gradually begins to decline.
Conclusion
In conclusion, the urn-shaped age pyramid is the appropriate graphical representation of a declining population. It is an important tool used by demographers to study population trends and to identify the demographic challenges facing a population. Understanding the age pyramid and its different shapes is essential in understanding the population dynamics of a region or country.
