Why was the year 1921 called as the year of great divide in the history of population growth in india ?
Because up till the year 1921 India recieved a stagnant growth rate as per thepopulation cendus recorded the same year. It was the first phase of demographic transition till 1921 featured by high birth rate and high death rate. In same year fact came that the innfant mortality rate was also very high that year.Thereafter, India passed through successively all the phases of demographic transition and is now widely believed to have entered the fifth phase, usually characterized by rapidly declining fertility wih the forecoming problem of alarming population figures raising day by day.
The growth rate of population was generally low before 1921. But after this year, there has been considerable and continuous increase in the population.
Between 1901 and 1911, the total increase in population was 5.9% and between 1911 and 1921, there was a decrease of 0.39%. In the decade of 1921-1931, the increase was 11.1%, from 1931 to 1941, it was 14.00% and during 1941-1951, it was 13.5%. It is going increasingly since then. Hence the year 1921 is rightly called the demographic divide.
