We've been in Idaho 4 years and in that entire time I've seen 2-3 instances of open carry and zero instances of concealed carry; concealed means concealed but I'm a pretty observant old dude. OTOH, I'm a retired old dude and my interaction with the general population is low bandwidth: the range (everybody is carrying something - doesn't count), Jackson's for gas, coffee shops, Home Depot, other miscellaneous. You would think in all this time I would have detected one concealed handgun. Might be different in the big city downtowns: Boise, Eagle (too many Californians), Nampa, Caldwell. Anecdotally, the percentage in Idaho appears low.
