India doesn't has way bigger problems than winning Olympic medals, hence their athletes are not funded well and many of them do not stick with their sport as they need to make money.

Why wasn't there any Native Americans competing?

Population doesn't matter. Willingness and ability does.

because they just play cricket and they didn't know how to play other sports.

Well SOMEONE has to answer the phone don't they?

Isnt india the second most populated country after China in the world? i have watched alot of these olympics and i havent seen any Indian athletes competing. Just wondering, why arent there alot of Indian athletes in the Olympics? does the government not fund them?
