Mostly from Asia generally. India, Thailand, Indonesia, Phillipines especially. There was a study mentioned here on HN a few months ago. If someone wants it I can look it up for them. There is still a case to be made that we (the more developed world) should practice what we preach and set a good example. Personally I re-use all my plastic bags and they all end up in land-fill.
