Unfortunately, your assessment overlooks the ever-present elephant in the room: the climate crisis. Annual grasses such as wheat, corn, and rice are the staple of most of humanity today, yet they are all extremely sensitive to hotter and drier climates worldwide, to say nothing of massive floods like the one that recently inundated Pakistan, and routinely inundates Bangladesh. These also wipe out cereal crops en masse, all at once.

My point is this: there are far more immediate existential threats to India's (and the entire planet's) population than demographic trends! In 50 years, we'll be lucky to be alive at all, no matter our age. And the way things are going now, we may not even want to be alive!
