Answer:

answer: 

There is a database called Polling the Nations that might provide the kind of survey data you're looking for. You can search it without a prescription, but can't review the responses.

I searched < occupy > after September 2011. There were four results, but they all questioned US people only.

I also tried < economic crisis >, which yielded 366 results, some US, some international.

Would you care to formulate some searches/queries and let me know which responses you want to see? Or if you can tell me which countries/regions you're especially interested in, I can poke around myself.
