Have you read much about the history of the various occupations? With the entirely honorable exception of Denmark and Norway, and the surprising partial exceptions of Serbia, Italy and Hungary, most of the regimes in the occupied countries cooperated in the hunt for Jews. Some were highly enthusiastic, like Croatia and Slovakia. Even the Dutch and French were in general helpful to the Gestapo.
I don't have any statistics, but the facts are widely available. That's why the state of Israel has honored those who resisted and helped protect Jews.
So you can't produce the facts, you just decided to make that unsubstantiated post that the majority of citizens were eager.
