Q.  The age and sex structure of a population may be best described as:
A. Life table
B. Correlation coefficient
C. Population pyramid
D. Bar charts

Correct Ans: Population pyramid

Explanation: Population pyramid, also called an age structure diagram or an age-sex pyramid, is a graphical illustration – typically in the shape of a pyramid- which depicts the distribution of various age groups for each gender in a geographical area such as the European Union, a country or a region.

FAQ: Frequently Asked Questions by Peoples

Q. What is the age and sex of members of a population?

Ans: The composition of a population as determined by the number or proportion of males and females in each age category. The age-sex structure of a population is the cumulative result of past trends in fertility, mortality, and migration.

Q.What represents the age-sex structure of a population?

Ans: Age-sex structure is represented by a population pyramid. This is a bar graph, like the one Figure below. In this example, the bars become narrower from younger to older ages.

Q. How do we describe the age structure of a population?

Ans: 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.

Q. What is an example of age structure?

Ans: It is common in demography to split the population into three broad age groups: children and young adolescents (under 15 years old) the working-age population (15–64 years) and. the elderly population (65 years and older)

Q. What are the factors affecting age sex structure?

Ans: The demographic processes of fertility, mortality, and migration produce the population’s age and sex structure (Horiuchi and Preston, 1988), and the age and sex structure influences the demographic processes.

Q. What are the 4 types of population?

Ans: Finite Population.
Infinite Population.
Existent Population.
Hypothetical Population

Q. What is meant by age structure of the population class 12?

Ans :Age structure is nothing but division of the population of a nation into three broad categories – Children (generally below 15 years of age), Working Age (15 – 59 years), Aged (Above 59 years).

Q. What does the age structure of a country’s population depend on?

Ans: Age distributions differ among countries mainly because of differences in the levels and trends of fertility. A population with persistently high fertility, for instance, has a large proportion of children and a small proportion of aged persons.

Q. Why is age and sex structure important in population studies?

Ans: It may be described in terms of absolute numbers or percentages. Because of the importance of the age-sex structure as a starting point for demographic investigation, a specific way of depicting them graphically has been developed. These depictions of age-sex structures are called population pyramids.

Q.What are the different types of age-sex structure?

Ans: There are generally three types of population pyramids created from age-sex distributions– expansive, constrictive and stationary. Examples of these three types of population pyramids appear at the end of this report.

Q. Why is the age structure of a population important?

Ans: As age structure suggests, some individuals within a population have a greater impact on population-level processes, such as growth. Fecundity describes the number of offspring an individual or a population is able to produce during a given period of time (Martin 1995) (Figure 4).
