Answer» (i) According to the population estimates of India, till 1871, Indian’s population recorded a modest growth. Since then the population has been increasing consistently. However, in 1921, population growth declined to 0.30% caused by large-scale deaths caused by diseases like influenza, plague, cholera etc. This is why 1921 is called the ‘demographic divide’. (ii) During 1921-1951, the population of India increased from 251 million to 361 million, registering a growth rate 47.3%. During 1951 1981, the population nearly doubled from 361 million to 683 million, a growth rate of 89.2%. In 2001, the population stood at 1027 million registering a growth rate of about 50%. This is why the period from 1951-1981 is referred to as the period of population explosion. |
