Pilots flying without a license, this one is easy: none of them
(ok, some might be picky and point out that folks flying with a
certificate issued under 14 CFR 61.75 do indeed need a license in
addition to their certificate, if their country of origin issues
one).

as for folks flying without a medical; well, you have all the
glider pilots to boot, and they have been doing that for a long
time, no problem; and pilots with sport pilot certificates. (I
don't know about ultralights pilots but I reckon they don't need one
either); To that lot, you can also add a number of instructors,
since a valid medical is not required to instruct a student who is
already certificated.

Actually, I meant how many pilots are flying illegally (because they
lack a valid license or a current medical, for example)?

Well, not you, even though you don't have a licence, you don't fly!
