Demographic stats on semantic web expertise?

Does anyone know of statistics that would indicate where 
(geographically) semantic web expertise is located, and in what 
industries semantic web people are working?   For example, do we have 
any data like this about the subscribers of the semantic-web@w3.org 
list?  Or the members of the public-semweb-lifesci@w3.org list.

Does the W3C have anything like this?

Any suggestions?
