I said medium to high.
In my own world magic is perceived as rare when, in reality, it's not at all.
About 20% of the population has magical talent, most are just very basic/mundane and self-taught (usually even without realizing they are using magic). The old lady down the street that makes charms, the nurse up the road that has a knack for healing injuries, the animal handler that can work wonders with cranky horses, etc.
About 5% of the 20% (so about 1% of the population) would be considered "Semi Spell Casters". Many of these are Paladins, a good number of them Rangers, and the rest are a mish-mash of everything else.
About 1% of the "Semi" casters (so about .01% of the population) would be considered "Pure Spell Casters" and a probably over half of them are Priests. Full on "Magicians" (of the fireball throwing sort) are held in awe - sometimes fear (and some of the religious orders would happily hunt them all down and kill them if they could).
Weapon and Item bonuses almost always start with Materials and Quality of Craftsmanship the move on to Magical properties. Items with a bonus of +5, +10 and sometimes even +15 will be 'non-magical' in nature. +20 on up is nearly always magical.
