No, they haven't. As of 2013, the UN projected India's population to surpass China by 2028, and peak at ca. 1.6 billion in 2050, and fall back to about 1.5 billion by 2100.

For comparison China is expected to start declining around 2030, and fall to around 1.1 billion by 2100.

How in the world can someone make anything but a wild ass guess about what the population patterns will be 84 years from now? Even 20 year predictions are dubious IMHO.
