(iii) The magnitude of population growth refers to
(a) The total population of an area
(b) The number of persons added each year
(c) The rate at which the population increases
(d) The number of females per thousand males
Answer: (b)
Explanation:
Population growth is the rate of growth of population it is typlically expressed as percentage of original population. However, the questions is not asking about the growth rate, it asks about the “magnitude of population growth”. Magnitude of population growth is the number of people that have been added since last period (last year, last decade etc.). For example the following graph gives the population of India in various years. To compute manganite of the growth between 2014 and 2012 we would do However, the rate of growth in percent is given as . Note that even though the rate could be smaller manganite of the growth could be large. The rate of population growth between 2006 and 2014 has gone down, however India is still adding more people to its population, then it was doing a decade ago.
(iv) According to the Census 2001, a “literate” person is one who
(a) Can read and write his/her name
(b) Can read and write any language
(c) Is 7 years old and can read and write any language with understanding
(d) Knows the 3 ‘R’s (reading, writing, arithmetic)
Answer: (a)
The working definition of literacy in the Indian census since 1991 is as follows:
Literacy Rate
The total percentage of the population of an area at a particular time aged seven years or above who can read and write with understanding. Here the denominator is the population aged seven years or more.
Crude literacy rate
The total percentage of the people of an area at a particular time who can read and write with understanding, taking the total population of the area (including below seven years of age) as the denominator.
Therefore,

Crude literacy rate = number of literate person divided by total population multiplied by 100

Effective literacy rate (or literacy rate) = number of literate persons aged 7 or above divided by population aged 7 and above multiplied by 100
