Maybe you have different numbers than I can find but all of the graphs of population growth show pretty much the same thing for India or China as they do for other countries: an almost flat increasing trend that hockey-sticks as soon as the country modernizes and then begins to level off or decrease as education catches up. The historical population of India seems large until you consider that the subcontinent is the size of Europe and then factor in the earlier start they had compared to Europe and there's no mystery left.
