The original data is mostly government statistics and the original sources are all cited. Are you asserting that heritage lied about the contents of the reports they cite?

Or are you simply saying "people I don't like wrote the report, therefore it must be invalid"?

The review article I linked to did indeed cite several studies of the type you are asking for.
