I'm afraid, there is not a straight forward report that will output this information quickly/painlessly at this time. However, if you use products or subscriptions, you can view the purchases for that product in ACP -> Commerce -> Store -> Products -> on your product, click the active number of individuals (or expired doesn't matter). You can then use that screen at least to help narrow your search down a bit via the advanced search to get dates, active purchases, etc...
None-the-less, I will move this to our Feature Suggestion forum as I think this is a pretty valuable report to have and we could possible expand on this with other statistics from the community such as content, reputation, achievements, etc...
