What is the purpose of age structure?
Age structure data allow the rate of growth (or decline) to be associated with a population's level of economic development. For example, the population of a country with rapid growth has a triangle-shaped age structure with a greater proportion of younger individuals who are at or close to reproductive age.
Why is it important to know the age structure of a population?
Age structure is useful in understanding and predicting population growth. For instance, if you know the age of first reproduction and reproductive strategy of a population, from the life history we mentioned earlier, then you can predict future population growth patterns based on age structure data.
What is the meaning of age structure?
Definition English: The age structure of a population is the distribution of people among various ages. In graphic form, age structure is portrayed as an age pyramid whose relatively broad base indicates the number of children while the peak reflects the increasing likelihood of death as people age.

Age structure of the population refers to the proportions of persons in different age groups relative to the total population.
What does the age structure diagrams tell you about these countries?
An age-structure diagram provides a snapshot of the current population and can represent information about the past and give potential clues about future problems. When you are interpreting age-structure diagrams, it is important to compare the width of the base to the rest of the population.
Why is it important to know the age composition of a country?
The age composition of a country is an important characteristic of a population. A person age will determine buying preferences etc. and in turn will determine average salary, production patterns and urbanisation.
Why is it important for a country to know the age and gender structure of its population?
Any country needs to know the size and composition of its population – around age and sex structure, among other factors. Knowledge about distribution is important, too: where do people live and work? That helps to plan how many schools, clinics, hospitals and jobs a country needs.
Why are age structure diagrams used by scientists?
An age-structure diagram provides a snapshot of the current population and can represent information about the past and give potential clues about future problems. When you are interpreting age-structure diagrams, it is important to compare the width of the base to the rest of the population.
What is meant by the age structure of the population?
The age structure of a population refers to the proportionate numbers of people in different age categories in a given population for a defined time. It is a natural characteristic of a population in a country or a region. The age structure is closely related to the birth rate, death rate and migration of a population.
Which of the following benefit of the study of the age structure?
Answer : The study of age structure plays a very important role in the demographic statistics. The study of age structure indices helps to plan for the development of the economic and cultural life of the society.
What do you mean by age structure in a population?
The age structure of a population is the distribution of people of various ages. It is a useful tool for social scientists, public health and health care experts, policy analysts, and policy-makers because it illustrates population trends like rates of births and deaths.
How does age structure affect population size?
D Age structure Growing populations generally have larger proportions of individuals in younger age-classes, whereas declining populations usually have smaller proportions of individuals in these age classes. Stable populations usually have relatively more individuals in reproductive age-classes.
What can you predict about a population with an age structure?
Demographers can make many predictions based on age structure—the distribution of ages in a specific population at a certain time. For example, if a population has more young people than older people, the population size will likely increase as the young people grow up and have children.

What is meant by the age structure of the population Why is it relevant for economic development and growth?
It means birth rate in India is gradually decreasing. Due to the advancement in medical sciences, public health measures and nutrition the life expectancy is at rise. This is due to economic development and growth.
What can an age structure diagram tell us about a population?
An age-structure diagram provides a snapshot of the current population and can represent information about the past and give potential clues about future problems. When you are interpreting age-structure diagrams, it is important to compare the width of the base to the rest of the population.
How is the age structure of population relevant for economic development?
Economic development and improvement in quality of life improve life expectancy and changes the structures of the population. High infant mortality rate and material mortality rate due to poor economic growth hence an adverse effect of age structure on the population.
How does age structure affect population dynamics?
Age Structure and Population Dynamics☆ Age structure of males can influence breeding dynamics of age-structured populations. In polygynous species, populations with greater numbers of older, prime-aged males have earlier, shorter, and less socially-disruptive breeding periods.
How does age structure affect economic development?
An aging population and slower labor force growth affect economies in many ways—the growth of GDP slows, working-age people pay more to support the elderly, and public budgets strain under the burden of the higher total cost of health and retirement programs for old people.
How does age structure affect economy?
An aging population and slower labor force growth affect economies in many ways—the growth of GDP slows, working-age people pay more to support the elderly, and public budgets strain under the burden of the higher total cost of health and retirement programs for old people.
Are age structure diagrams useful in predicting future population trends?
Explanation: It is definitely useful. Age structure diagrams such as the population pyramid project how a population would look like in the years to come e.g a large ageing population or a large emerging young dependent population.

How does age structure affect birth rate?
The maturing of the age structure acts to slow down the decline in the birth rate. The extent of further declines in the rate of natural increase depends on the extent to which the crude death rate increases and/or the crude birth rate decreases.
Why is age structure important for economic growth?
Age structure effects on economic growth may be explained by life-cycle patterns in savings behaviour and in human capital accumulation. The life cycle theory of saving suggests that aggregate savings rates are influenced by age structure.

What is age structure in environmental science?
An age structure diagram is a model that predicts the population growth rate by a shape. It shows a comparative ratio of males to females and the bars show various age groups from infants – adolescents – reproduce – post-reproductive.
