If someone with a FHP were to request this information, it would be interesting to see what was listed. It looks like Exemption #6 would be applicable -
6. For use in research activities, and for use in producing statistical reports, so long as the
personal information is not published, redisclosed, or used to contact individuals.
The personal information could be redacted (blacked-out) in order to post it online. It would be good info to have.
