I'm sorry, but tor clients do not currently report any statistics.
Only tor relays report statistics.

We also get a limited set of OS/language statistics from Tor Browser
downloads and update pings.

But there is no protocol for tor clients to report statistics.

Any client protocol would need to have the following properties:
1. avoid client tracking, and
2. secure aggregation of counts for each type of client, so counts could
   not be linked to individual guards.

I'm not sure either of these things are possible in tor at this time.
They would require very specialised protocols.
