The fact that you're pretty far from a major metro probably accounts for some of it.
IDPA shooters tend much more toward the casual than USPSA shooters, which is why IDPA has had such success. IDPA shooters will likely not drive an hour and a half for a local match.
My experience in IDPA was that largely, with some exceptions, IDPA folks were people who shot guns amongst other hibbies or interests. USPSA shooters tend towards shooting being their primary hobby so they will travel further and spend more.
My take.
