Medically underserved areas (MUA) are areas where certain populations — usually rural — are subject to a lack of primary care and have high levels of poverty, infant mortality, and elderly people. As designated by the Health Resources and Services Administration (HRSA), these “shortage areas” can have both a “population” and “geographic” identify.
For example, a “geographic” shortage area would be a county, a group of counties, an urban census tract, or civil division where there’s a severe lack of primary care and health services, where a “population” shortage area, on the other hand, would most likely be a subset of that geographic location — such as people experiencing homelessness, low-income people, those eligible for Medicaid, Native Americans, or migrant farmworkers who may face language, economic, or cultural barriers to receiving quality health care.
And, as evidenced by the below information, these areas have not only been described, designated, and tracked by the HRSA, but they have also been mapped — a great resource for teachers, planners, and everyday learners who want to understand equity vs equality, health, and medical accessibility in the United States.

Vulnerable and Medically Underserved Populations Examples
In most situations, the term “vulnerable” can be used interchangeably with “underserved,” however, there are still some minor differences. Therefore, if you hear someone talk about “underserved populations,” it typically means that certain groups lack access (or have limited access) to health care services because of their location, but if you hear someone talk about “vulnerable populations,” it typically refers to those individuals who experience additional barriers — such as homelessness or extreme financial hardship — thus making that access to healthcare even more difficult.
For example, if someone has a serious health condition, they’re considered vulnerable, but if healthcare is accessible to them, then they’re not considered underserved.
Conversely, if someone doesn’t have accessible healthcare near them, they’re considered underserved, but unless they have some sort of limitation, then they may not be considered vulnerable.
Regardless of the academic definition, however, the most important thing to remember is that despite a few differences, there is usually a high level of overlap between both vulnerable and underserved populations, and in most cases, one usually exacerbates the effects of the other.
Vulnerable Populations
- People who experience significant hardship and have limited life options (e.g. access to affordable housing, lack of education, financial struggles)
- People who have cultural communication barriers (e.g. may not speak English in an English speaking town)
- People who can’t give (or have the limited ability to give) consent because of communication barriers or cognitive impairments.
- People who are at high risk for multiple health issues and may have pre-existing conditions
- People who have a strong distrust of government programs (may not be willing to disclose sensitive information)
- People who have or experience mobility impairments
- People who lack or have limited access to transportation services
- People who face discrimination
Underserved Populations
- People who face certain hardships when trying to access health care services
- People who live in certain locations where health care isn’t accessible or readily available
- People who lack or don’t understand health care delivery
- People who face economic or linguistic/cultural communication barriers when trying to access health care

Medically Underserved Areas Map Tools
HRSA Map Tool
The HRSA Map tool can be used to find a plethora of information on medically underserved areas – it can also be used to plot (1) HRSA facilities, providers, sites/areas, (2) HRSA grants, loans, scholarships, (3) population and public health data, or (4) add your own data.
MUA Find
MUA Find is a tool that can be used to search medically underserved area information by state/territory or subsequent counties. Apply a number of MUA/P Status filters and MUA/P Designation/Population types to visually see and analyze medically underserved areas across the United States.
Quick Maps – (MUA/P)
The Quick Maps – Medically Underserved Areas/Populations (MUA/P) map is an easy-to-use HRSA tool that visually displays medically underserved areas and populations across the United States. The tool includes a search box, legend, and quick maps guide (top right of the page).
Explore MUAs
“Explore MUAs” is an interactive dashboard that can be used to find medically underserved areas that have been identified as having a shortage of health care services. Explore the MUAs dashboard by selecting overview, type, or rural status, or use the “MUA/P Count by State” feature on the right to find specific state by state information.
