Hmm looks like some stats I pulled were from polls, and I fell victim to people paraphrasing that around 20% of rural people not having a primary care doctor in the last few years as "not even having seen a doctor" sorry about that.
40% of Americans haven't seen a doctor in 5 years: https://studyfinds.org/americans-avoiding-the-doctor/ https://www.aarp.org/pri/topics/health/coverage-access/health-care-rural-america/?
But the limited stats on primary care and a lot of self reporting is very bad.

Typing in "southern united states rural primary care access" in Kagi has a lot of sad results.
