The share of income ethnic Indians in the US send back to their folks in India is less than 15%. If this broad indicator is applied worldwide, the Indian diaspora, which remitted $125 bn last year, would be producing economic output approaching the GDP of Switzerland, or about 0.8% of world output. However, Indians all over are not as well off as they are in the US. So, this rough estimation can, at best, be regarded as the outer limit of the diaspora's contribution to the world economy.
