It shows that during 1901 to 1951, the population grew at 12.27 crore in 50 years with 51.46 per cent growth rate. The decadal growth is 5.75% in 1911, 0.31 in 1921, 11% in 1931, 14.22% in 1941 and 13.31% in 1951. This period may be termed as idle growth. During 1961 to 2011 (the next 50 years), the population increased by 77.10 crore with 181.39% growth rate which is on very higher side. It was surprising that decadal growth of population increased from 13.31% in 1951 to 21.64% in 1961, 24.80% in 1971, 24.66% in 1981, 23.87% in 1991, 21.54% in 2001 and 17.64% in 2011. Thus, a trend of population explosion started after 1951.
Almost all States and Union Territories also show the same trend in increase of population after 1951. It is observed that consolidated annual growth rate of population in 2011 is 1.76%, whereas the States like Jammu and Kashmir, NCRT, Rajasthan, Uttar Pradesh, Bihar, Arunachal Pradesh, Jharkhand, Chhatisgarh, Madhya Pradesh, Daman & Diu, Dadar Nagar Haveli, Pondicherry and Andaman & Nicobar Islands registered a growth rate of more than 2% which is on very higher side, though in some States migration from Bangladesh may be the factor. India needs to launch an overall population awareness programme
