Archives.gov has an interesting "Statistical Summary of Holdings", which consists of a list of every record group or collection with a breakdown of its name, topic cluster, material type, location by unit code and name, size of the holdings by location, total size of the record group/collection, and links to its Guide to Federal Records listing. Unfortunately, this is just in HTML tables—not machine-readable or able to be manipulated—and spread across 7 pages.
I think this holdings statistical data would be a great addition to the Public Data Listing!
