Question

research on last 3 census and find the reason for population explosion in India and Afghanistan

Answer 1

  1.    The area covered by the sixth general census of India is approximately identical with that covered by the census of 1921 and differs little from the area of previous occasions from 1881 onwards; 2,308 sq. miles containing some 34,000 inhabitants have been added in Burma and in the North of Assam, while on the other hand, six sq. miles have been lost to Nepal. The statistics therefore cover the whole empire of Indiislands and islets (Exclusive of Ceylon and the Maldives) as well as Aden and Perim Island, but not the Kuria Muria Islands* and Sokotra, which is part of the Aden Protectorate, administered from Aden on behalf of the Colonial Office, and not part of British India. The statistics the tables do not of course cover those parts of the peninsula, which are not parts of the British Empire, that is to say, Afghanistan, Nepal, Bhutan and the French and Portuguese possessions, the area and population of which, together with the rate of increase since 1921 where available, are shown in the marginal table. For the rest the scope of this census extended to the whole of the peninsula of India, forming what is commonly described as a sub continent between long. 61 o and 101 o E. and lat 6 o to 37 o N. Some information has also been included with regard to natives of India resident permanently or temporarily outside the Indian Empire or serving on the High Seas at the time the census was taken. Obliviously within an area of sucha with, Burma and the adjacentsize, part of which is well within the temperate zone while part is almost equatorial, the diversity of condition both of the population and of its environment must be very great indeed. Geologically, while the peninsula is one of the oldest of the world's formations, the Himalayas are one of the most recent. Not unnaturally therefore there is a great variety of physical feature, varying not only from the loftiest mountains of the world to flats salted by every tide, but from sandy deserts with a rainfall of five inches or less in a year in the north west  to thickly wooded.
