Healthcare Deserts vs HRSA Shortage Designations
“Healthcare desert” is informal shorthand. HRSA Health Professional Shortage Area and Medically Underserved Area records are the comparable federal designations, and they do not measure a person’s access to a particular appointment, hospital, insurer, or health outcome.
The short answer
A shortage designation is a source-defined provider-supply record. It supports county and state comparison, but it is not a measurement of service availability or health outcomes. According to the HRSA Data Warehouse, the live figures below describe federal provider-supply designations, not care quality or appointment availability.

Where Medically Underserved Area records concentrate
MUA is the broader, separate HRSA designation this guide distinguishes from an HPSA. Count of active MUA records by state -- a different population than the HPSA totals shown on other guides, since a place can hold one, both, or neither designation.

What the Records Describe
Health Professional Shortage Area (HPSA) and Medically Underserved Area (MUA) records are federal, source-defined designations. The data can identify the type of designation, its score where reported, the covered geography or population, and the source vintage. PlainHealthAccess uses those records to make comparisons across its county and state views.
The phrase healthcare desert is broader than either designation. It is useful shorthand in public discussion, but it should not be treated as a measured category in this dataset.
What the Records Do Not Measure
A designation does not answer whether a particular clinician is accepting patients, whether an insurer covers a visit, how far a person must travel, whether a hospital or service line is operating, or what health outcome a community will experience. Those questions require separate, current sources and often an individual provider, insurer, or public-agency check.
This distinction matters when comparing places. A high score is a description of the recorded HRSA designation criteria, not a clinical assessment of a resident, a prediction of care quality, or proof that all local services are unavailable.
How to Compare Places Responsibly
- Start with the same category: primary care, mental health, dental, or MUA.
- Check the source vintage and the geographic or population basis of each record.
- Use the county and state pages to compare recorded designations and scores, rather than inferring individual care access.
- For current services, confirm availability with the relevant health system, insurer, public agency, or HRSA Health Center Finder.

Frequently Asked Questions
What is a healthcare desert?
Healthcare desert is an informal phrase, not an HRSA designation. PlainHealthAccess reports HRSA Health Professional Shortage Area and Medically Underserved Area records, which describe federal provider-supply and underserved-area criteria.
What can this data tell me about my county?
It can show the current HRSA records linked to a county, their shortage category, score, and source vintage. It is useful for comparing recorded designations, not for determining an individual’s care options.
Does a shortage designation measure health outcomes?
No. The HRSA records used here do not measure life expectancy, mortality, disease outcomes, travel time, appointment availability, insurance acceptance, hospital operations, or care quality.
Can a county have more than one designation?
Yes. HRSA records different shortage categories separately, so a place can have records for primary care, mental health, dental care, or a medically underserved area. Compare the category and vintage before drawing conclusions.
Where should I look for current care options?
Use the relevant health system, insurer, public health agency, or HRSA service finder for current availability and eligibility. A shortage designation is a planning and comparison signal, not a provider directory or clinical recommendation.
Put this in context
California carries the most recorded MUA designations in this snapshot -- a separate population from the HPSA totals shown elsewhere on this site.

An MUA or HPSA record describes HRSA's federal designation criteria, not appointment availability, insurance acceptance, or care quality.
