The following arguments justify the given statement
(i) Since 1981, the growth rate started declining.
(ii) During this period, birth rates declined rapidly.
(iii) Still 182 million people were added in the 1990s.
(iv) When low annual rate is applied to a very large population, it yields a large absolute increase.
(v) When more than a billion people increase even at a lower rate, the total number being added becomes very huge.
Thus, it can be concluded that despite the declining trend of growth rate, the population of India is increasing at fast rate.
