Most Indians do live in the north of the country (or at least, the north is the most densely-populated part, whether it is home to an actual majority of the population or not), but that’s actually the humid subtropical part. Compare this population density map to this climate map. Of course it’s possible that you’re still right that it’s the climate and some other factor pushes India’s rate down regardless, like the massive population density meaning high demand for food or the country being quite poor per capita compared to the others on this list

Good point, as I said, there’s probably (many) more factors at play here.
