Almost every health gradient in this book slopes the same way: worse where deprivation is higher. One refuses. People in the poorest neighborhoods see a doctor just as often — and walk out with far less prevention. The system is there. It is managing disease where it could be preventing it.
Sort America's neighborhoods by deprivation and most things about health get worse in lockstep — more diabetes, more smoking, shorter lives. The tidy inference is that deprived places are health-care deserts: fewer doctors, fewer visits, less of everything medical. The data say something stranger and more damning.
The CDC's small-area health estimates let us follow each kind of care down the deprivation axis separately. What emerges is not a desert. It is a system that shows up — and then does the wrong half of its job.
Here are two kinds of care on the same axis. Routine checkups are flat — in fact slightly higher in the most deprived tracts, because sicker populations come in for management. Dental visits, almost pure prevention, collapse from 70% to 46%. Same patients, same neighborhoods, opposite slopes. The doctor's visit happens; the cleaning, the screening, the prevention does not.
Lay every measure side by side as its change from the least- to the most-deprived decile. A clean pattern falls out. Prevention drops (cancer and cholesterol screens, dental). Barriers rise (uninsured, care skipped for lack of transport). Disease and its maintenance rise (diabetes, smoking, blood-pressure medication). And the annual checkup sits on the wrong side of zero — a contact measure that goes up while everything preventive goes down.
The preventive services, panel by panel, all bend down the deprivation axis — and the access barriers bend up. The exception, boxed in teal, is the annual checkup: the one line that refuses to fall. Contact with the system is not the scarce resource in deprived America. Prevention is.
This project treats flat lines as clues. A gradient that refuses to tilt is telling you that whatever drives the other gradients is being held off here — and the question is by what, and at what cost. The checkup's flatness is good news with a sting: deprived neighborhoods are not cut off from medicine, so the worse outcomes downstream cannot be blamed simply on people not showing up.
What is missing is the cheaper, earlier half of care — the screen that catches the cancer at stage one, the cleaning that saves the tooth, the statin before the heart attack. A system that reliably treats the diabetes it could have prevented, and fills the prescription for the blood pressure it could have screened, is not absent. It is arriving late, on purpose, everywhere the map is darkest.
