What can be known is *how* TOR is being used by setting up studies at exits and seeing what kind of services people are connecting to.
Keeping logs of Tor related traffic on nodes -- a prerequisite for analysing behaviour -- is not only a bad idea that weakens anonymity, but is also potentially illegal.
Service providers can evaluate the percentage of incoming connections from Tor exit nodes (exit lists are publicly available), but Tor nodes should never keep a record of the source or destination of the traffic they're routing, or of DNS lookups.
