The replacement level of total fertility rate for India is
- A.1.0
- B.2.1
- C.2.5
- D.0
Correct answer
Explanation
The correct answer is B, 2.1. Replacement level fertility is the total fertility rate at which a generation of women exactly replaces itself in the next generation. It is slightly above two rather than exactly two, because some girls do not survive to the end of their reproductive years and slightly more boys than girls are born, so the accepted figure for India and for most countries is about 2.1 children per woman. Option A is wrong because a rate of 1.0 is far below replacement and would halve the population in a generation, as in parts of East Asia and Europe. Option C is wrong because 2.5 is above the replacement level and still implies growth. Option D is wrong because a total fertility rate of zero would mean no births at all. Remember the figure as two point one.

View allThe density of population is usually expressed as
- A.Persons per square kilometre
- B.Square kilometres per person
- C.Persons per thousand births
- D.Births per thousand persons
Show answer

Show answer
In this essay of 1798 Malthus argued that population tends to increase in a geometric progression while the means of subsistence can increase only in an arithmetic progression, so growth must be restrained either by positive checks such as famine, disease and war, or by preventive checks such as late…

Read the full explanation →In which stage of the demographic transition are both the birth rate and the death rate high, so that population grows slowly?
- A.The first or high stationary stage
- B.The second or early expanding stage
- C.The third or low stationary stage
- D.The stage of population explosion
Show answer
In the first stage of the demographic transition the society is rural and agrarian, life expectancy is low, medical facilities are poor and literacy is low, so both the birth rate and the death rate are high and they roughly cancel each other, leaving population almost stationary.

- A.A declining population
- B.A high birth rate and a young population
- C.An equal number of men and women
- D.A high dependency of old people
Show answer
The width of each bar in a population pyramid shows the share of that age group, so a broad base means that children form a very large part of the population, which happens where the birth rate is high; the narrow top shows that few people survive to old age.
