A. Dependency Ratio is a measure comparing the portion of a population composed of dependents with the portion in the working age group
B. Infant mortality rate is the number of births of babies before the age of one year per 1000 live birth
C. Growth rate of population refer to the difference between the death and fertility rate
D. Fertility rate refers to the number of live births per 1000 women in the child-bearing age group (15-49 years)
E. Age Structure of a population refers to the proportion of a specific age group to the average population
Choose the correct answer from the option given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → B, C, and E only
A. Dependency Ratio is a measure comparing the portion of a population composed of dependents with the portion in the working age group A correct explanation (Incorrect). The dependency ratio compares the dependants, that is, elderly people too old to work and children too young to work, with the population of working age, generally taken as 15 to 64 years.
B. Infant mortality rate is the number of births of babies before the age of one year per 1000 live birth Not a correct explanation (Correct). The infant mortality rate is the number of deaths of babies before the age of one year per 1000 live births. One word, ‘births’ in place of ‘deaths’, turns a definition false, so check each word before you tick it.
C. Growth rate of population refer to the difference between the death and fertility rate Not a correct explanation (Correct). The growth rate of population is the difference between the birth rate and the death rate. The fertility rate is a different measure, counted per 1000 women of child-bearing age, so it cannot be set against the death rate, which is counted per 1000 of the whole population.
D. Fertility rate refers to the number of live births per 1000 women in the child-bearing age group (15-49 years) A correct explanation (Incorrect). This is the fertility rate as defined: live births per 1000 women in the child-bearing age group, usually taken to be 15 to 49 years.
E. Age Structure of a population refers to the proportion of a specific age group to the average population Not a correct explanation (Correct). The age structure is the proportion of persons in different age groups relative to the total population. It covers all the age groups, and it is measured against the total population, not an ‘average’ one.
NCERT (2025-26): “2.1 Some Theories and Concepts in Demography … The rate of natural increase or the growth rate of population refers to the difference between the birth rate and the death rate. When this difference is zero (or, in practice, very small) then we say that the population has ‘stabilised’, or has reached the ‘replacement level’, which is the rate of growth required for new generations to replace the older ones that are dying out.…” “…The fertility rate refers to the number of live births per 1000 women in the child-bearing age group, usually taken to be 15 to 49 years.…” “The infant mortality rate is the number of deaths of babies before the age of one year per 1000 live births. Likewise, the maternal mortality rate is the number of women who die in childbirth per 1,00,000 live births.…” “…The age structure of the population refers to the proportion of persons in different age groups relative to the total population. The age structure changes in response to changes in levels of development and the average life expectancy.…” “…The dependency ratio is a measure comparing the portion of a population which is composed of dependents (i.e., elderly people who are too old to work, and children who are too young to work) with the portion that is in the working age group, generally defined as 15 to 64 years. The dependency ratio is equal to the population below 15 or above 64, divided by population in the 15-64 age group.…” |
