Holly: I don’t think you’ll find this. It’d take some lifting by researchers, and I don’t think there are either thorough or quick/dirty takes on these models as NFC has defined them. The one big source of mission and spending info is from Form 990s, and these would have some limitations in answering your question. For one, there’s no reliable indication of whether an organization is a membership association or not. For another, government revenue is notoriously difficult to suss out of the 990, since earned income from contracts isn’t divided by source. This is a road we may try to get down a bit, but the data presents an assortment of challenges.
