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.
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.
How does age structure and economic development affect the human population growth?
The age structure of a population is an important factor in population dynamics. Age structure is the proportion of a population at different age ranges. Age structure allows better prediction of population growth, plus the ability to associate this growth with the level of economic development in the region.
How does age affect population growth?
In the slow growth model, the number of individuals decreases steadily with age. Stable population diagrams are rounded on the top, showing that the number of individuals per age group decreases gradually, and then increases for the older part of the population.
What is the significance of the age structure?
Age structure represents the number of people of different age groups. This is an important indicator of population composition, since a large size of population in the age group of 15- 59 indicates a large working population.
How does the age structure of a population help predict future population growth?
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.
How does age structure help us predict population growth?
Age structure has a better chance of knowing the outcome of population growth because the increase or decrease in age structure is based on the population’s development in economies.
What does the age structure of a population tell us?
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 benefits 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.
Why is age structure of a population important to demographers?
As age structure suggests, some individuals within a population have a greater impact on population-level processes, such as growth.
What are the determinants of age structure?
These changes in countrywide population age structures, as well as possible shifts in sex composition, are determined by three factors: fertility, mortality and international migration. These are essentially the proximate determinants of national age structural (and sex compositional) change.
What are the factors that affect population growth?
The two main factors affecting population growth are the birth rate (b) and death rate (d). Population growth may also be affected by people coming into the population from somewhere else (immigration, i) or leaving the population for another area (emigration, e).
What is 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 age structure pattern reflects a population with a declining population?
Which age-structure pattern reflects a population with a declining population? the youngest, or pre-reproductive, age classes are the smallest.
What is economic age structure?
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.
Which age group is economically most important?
According to this measure an average young person stays economically dependent for around 5 years longer (up to age 23–26 as indicated by the lower age borders in Table 1) than assumed in the demographic dependency ratios where the life cycle stage of young dependent people has been assumed to be delimited by age 20 (
What is the age structure of the country?
The age structure of a country has a strong impact on society and the economy. If the proportion of 0–14-year-olds is very high, there may be a so-called youth bulge. If, on the other hand, the proportion of over 65 is very high, the social systems of a country can be heavily burdened.
What are the determinants of age structure?
These changes in countrywide population age structures, as well as possible shifts in sex composition, are determined by three factors: fertility, mortality and international migration. These are essentially the proximate determinants of national age structural (and sex compositional) change.
Why is age an important demographic?
The Significance of Age and Sex Data
Understanding a population’s age composition, usually examined by sex, yields insights into changing population conditions and can highlight future social and economic trends.
Why is age structure of a population important to demographers?
As age structure suggests, some individuals within a population have a greater impact on population-level processes, such as growth.
