I live in Malaysia where approx 10% and 2.5 million of the pop are Indian Malaysian.
There is very little interest in cricket in this large group of people. I assume that it is because their families have been here for close to 200 years and they are still relatively disadvantaged people. That makes sense to me. They came to Malaysia before cricket spread internationally and, while ethnically Indian, they are culturally removed.
An Indian teammate of mine brought the fact that they are Tamil speakers into the equation. I don't know what that means. Were Tamil speakers from Southern India historically less inclined towards cricket until recently?
