this's been quite the challenge..
i browsed through all of the relavent databases my school subscribes to and couldn't find exactly, what you're looking for. i did find something, so i'll send it to you - pm me with your email. it came from a world bank database too, so good luck finding more specific data. the problem i've found is that no database breaks the data down to the level that you asked for.
aside from the file i have, maybe this link could help you:
