Where can I find raw intelligence quotient (IQ) data, ideally with age/birthday/etc? I followed the links in the answer to IQ scores from individuals and their siblings and/or twins but nothing there appears to be helpful.

I've found and read several studies that discuss IQ-to-birthdate correlation, but many of them refer to previous studies, and I can't find the original studies and/or the actual raw data used by those original studies.
