Not nearly as many people as in the US. But between ranching and leaving them in the wild, about 1/3 of all cows in the world are in India. As you might have caught, most of the cows in India are actually used for milk... which is a real problem because the lower tech means they get dramatically less milk per cow than we get in the US. As in, 1/4 as much.

The environmental impact of the Indian cow population is non-trivial, both because of how many cows are not used for food and how inefficient their food processes are with cows. In comparison, the environmental impact of the US cow population is arguably quite trivial. Ditto with the other large beef/milk consumers of the western world like Spain.
