For ownership purposes in most jurisdictions in the US, private ownership is anything that's not government. It includes individuals, privately-held & publically-traded corporations, and most trusts or other legal entities that aren't government controlled. There might be different tax polices and exemptions carved out for the different entities, but the legal structure of ownership is the same. This does not include anything federal, military, state, or local (including tribal) government, or is otherwise a special case, like some conservation non-profits, or things like public land trusts. But if any part the government wants to expropriate or otherwise seize privately held land, it has to go through the same process no matter what type of legal entity.
