In which of the following census decades India registered the lowest percentage change in population?

1971 - 1981
1981 - 1991
1991 -2001
2001 -2011

The correct answer is (c).

The percentage change in population in India from 1991 to 2001 was 21.3%, which is the lowest among the given options. The percentage change in population from 1971 to 1981 was 24.66%, from 1981 to 1991 was 23.85%, and from 2001 to 2011 was 17.64%.

The decline in the percentage change in population from 1991 to 2001 can be attributed to a number of factors, including:

  • A decline in the fertility rate. The total fertility rate in India declined from 3.2 in 1991 to 2.6 in 2001. This means that women are having fewer children on average.
  • An increase in the average age of marriage. The average age of marriage for women in India increased from 18.3 in 1991 to 20.9 in 2001. This means that women are having children later in life, which also contributes to a decline in the fertility rate.
  • An increase in the use of contraception. The use of contraception in India increased from 46% in 1991 to 56% in 2001. This means that more couples are using contraception to prevent pregnancy, which also contributes to a decline in the fertility rate.

The decline in the percentage change in population is a positive development for India. It means that the country is becoming more developed and that people are having fewer children. This will put less strain on the country’s resources and will help to improve the quality of life for all Indians.
