The Last Counter Standing: Pharmacy Closure and the Unequal Geography of Filling a Prescription

The closure of a pharmacy rarely makes national news. There is no dramatic scene — shelves emptied, a sign taped to the glass, patients redirected to a location miles away. Yet for the households affected, the departure of a neighborhood drugstore can function as a quiet restructuring of daily life, one that determines how far a person must travel to manage diabetes, refill an antipsychotic prescription, or obtain an antibiotic on a Friday evening. Peer-reviewed research increasingly frames this phenomenon not as a retail inconvenience but as a measurable restriction on human mobility with disproportionate consequences for those least equipped to absorb it.

Quantifying the Desert

Scholars define a pharmacy desert using thresholds adapted from food-access research: urban census tracts where residents must travel more than one mile to reach a pharmacy, and rural tracts where the threshold is ten miles or more. Studies applying these measures to national data have found that roughly one in ten Americans lives in such a tract, and that the population of deserts is systematically poorer, older, and less likely to own a vehicle than the population living within convenient reach of a pharmacy counter.

The recent wave of closures among major chains has accelerated the problem. Between 2020 and 2023, thousands of retail pharmacy locations shut their doors, and a 2024 analysis published in Health Affairs estimated that more than half of the affected stores were located in lower-income urban neighborhoods. Independent pharmacies — historically the backbone of rural drug access — have closed at an even faster rate, squeezed by reimbursement rates that often fall below acquisition cost and by the loss of prescription volume to mail-order programs.

The result is a pattern that mobility researchers would recognize immediately: access is not declining uniformly. It is thinning precisely where transportation options are scarcest.

The Invisible Mobility Tax

For a household with a car, a pharmacy four miles farther away is a minor friction. For a household without one, it may be an hour-long trip each way on a bus route that runs hourly — if it runs at all. Transportation researchers have begun to describe this gap as an implicit tax: the additional time and money a patient must spend to perform a task that, in a well-served geography, costs almost nothing.

The health consequences of this tax are not hypothetical. Studies of medication adherence consistently find that prescription abandonment rises with travel distance, particularly for chronic conditions requiring ongoing refills. One widely cited analysis of Medicare beneficiaries found that patients whose usual pharmacy closed were significantly less likely to fill statins and diabetes medications in the following year, with effects concentrated among those in low-density areas. Nonadherence, in turn, feeds the well-documented cycle of preventable hospitalization — a cost ultimately borne by public insurers.

There is also a dignity dimension that adherence statistics miss. An older resident of a rural county who must ask a neighbor for a forty-mile ride to pick up insulin is not merely inconvenienced; they are made dependent. Mobility, in the sense this journal uses the term, is the capacity to move through the world on one's own terms. Pharmacy deserts erode that capacity at its most intimate point: the maintenance of one's own body.

Improvised Alternatives — and Their Limits

Where formal access collapses, informal systems emerge. Patients consolidate refills into monthly trips; clinics dispense starter packs to bridge gaps; some health systems deploy mobile pharmacy vans; and mail order fills part of the void, at least for stable prescriptions. These adaptations are genuinely valuable, but the research record counsels caution about treating them as substitutes. Mail delivery fails for temperature-sensitive medications, for patients with unstable housing, and for those whose prescriptions change frequently. Mobile services cover small fractions of affected populations. And every improvised workaround shifts labor onto patients — typically the sickest and poorest — rather than onto the systems that produced the gap.

Policy Levers Worth Testing

A rights-oriented framework suggests that guaranteeing medication access should not depend on a zip code's attractiveness to retail capital. Several policy instruments are available to states and the federal government:

• Reimbursement reform. Medicaid programs in several states have begun adjusting dispensing fees to reflect rural cost structures, an approach that peer-reviewed evaluations suggest can slow independent pharmacy closures.
• Provider-status protections. Granting pharmacists broader clinical authority keeps rural counters viable and expands the services a single location can offer.
• Access mandates in payment contracts. Public insurers could condition network participation on geographic coverage standards, much as they already do for primary care.
• Transportation integration. Non-emergency medical transportation benefits, though chronically underused, could be streamlined so that a pharmacy trip is treated as what it is: a medical necessity.

None of these interventions requires treating pharmacy access as an extraordinary entitlement. They require only that policymakers measure the geography of the problem and treat distance as the barrier the evidence shows it to be.

A Baseline, Not an Accident

The deeper lesson of the pharmacy-desert literature is methodological as much as substantive. Retail closures are legible only when researchers combine business data with census geography and transportation access measures — a reminder that rights violations can hide inside ordinary market statistics. As this journal has argued in other contexts, from school boundary enforcement to rural transit loss, the question for scholars and policymakers is the same: who can reach the institutions they need, and at what cost? When the answer depends on where a store happens to close, access has been left to accident. The research base now supports treating it as a baseline obligation instead.
