उत्तर

The most important step to overcome this problem is to motivate smaller families by using various contraceptive methods.

  • Government of India advertises in the media as well as in posters, showing a happy couple with two children with a slogan “Hum Do Hamare Do” (We two, our two).
  • Many couples, mostly the young, urban working ones have even adopted a one-child norm.
  • Statutory raising of marriageable age of the female to 18 years and that of males to 21 years and incentives given to couples with small families are two of the other measure taken to tackle this problem.
