Health and Healthcare in Frontier Areas
Frontier areas are the most remote and sparsely populated places along the rural-urban continuum, with residents far from healthcare, schools, grocery stores, and other necessities. Frontier is often thought of in terms of population density and distance in minutes and miles to population centers and other resources, such as hospitals. Frontier areas may be defined at the community level by county, ZIP code or census tract; however, they are most often delineated by county.
Many frontier counties are located in the West, a part of the country where individual counties tend to cover a large geographic area. Even counties that have a town with a hospital, grocery store, and other services may also encompass areas that are much more rural and isolated, making them frontier counties. Frontier areas face challenges in providing access to health and human services which are even greater than the challenges faced by other rural communities.

What is the definition of frontier?
In general, frontier areas are sparsely populated rural areas which are isolated from population centers and services. Unfortunately, there is not a single universally-accepted definition of frontier. Definitions of frontier used for state and federal programs vary, depending on the purpose of the project being researched or funded.
While frontier is often defined as counties having a population density of six or fewer people per square mile, this simple definition does not take into account other important factors that may isolate a community. Therefore, preferred definitions are more complex and address isolation by considering distance in miles and travel time in minutes to services. A policy brief from the National Rural Health Association (NRHA) identifies several factors that may be considered in classifying an area as frontier including:
- Population density
- Distance from a population center or specific service
- Travel time to reach a population center or service
- Functional association with other places
- Availability of paved roads
- Seasonal changes in access to services
Frontier may be defined at the community level by county, ZIP code, census tract, or other defined geographic unit. See the National Center for Frontier Communities (NCFC) Defining the Frontier for descriptions of a variety of definitions that have been used through the years.
Commonly used definitions include:
Rural-Urban Commuting Areas (RUCAs)
Rural-Urban Commuting Areas (RUCAs) can be used to identify very remote areas, which could be considered frontier-like due to their isolation from population centers. Under the RUCA definition, types of rural and urban are defined by proximity to urban areas and the portion of the population that commute for work from place to place. For instance, a RUCA code of 10 is assigned to isolated, small rural census tracts, whereas a RUCA code of 1 is assigned to urban areas. RUCAs are available by census tract and ZIP code area.
Frontier and Remote (FAR) Codes
The USDA Economic Research Service (USDA-ERS) and the Federal Office of Rural Health Policy (FORHP) developed the Frontier and Remote (FAR) area codes to be used in research and policymaking. The FAR codes methodology uses urban-rural data from the 2010 Census population and urban area boundaries. Using population size, distance, time and geographic units this methodology produces 4 distinct FAR categories, which allows the user to determine how inclusive to be in designing their legislation, regulations, programs, or research.
The 4 FAR levels are determined by population density of an area combined with the distance from urban areas where they can access goods and services.
Information and maps on the methodology are available at USDA Economic Research Service: Frontier and Remote Area Codes.
Other frontier definitions include:
CMS Super Rural
The Centers for Medicare and Medicaid Services (CMS) provides enhanced ambulance service reimbursement in areas it designates as
super rural. This definition identifies these frontier areas as the bottom quartile of
rural (non-Metropolitan Statistics Area) ZIP Codes by population density.
BPHC Sparsely Populated Areas Criterion
The Bureau of Primary Health Care (BPHC) uses population density as a method to identify frontier service areas eligible for funding priority. BPHC defines a sparsely populated area as any service area with a population density no greater than 7 persons per square mile for the entire service area.
How much of the U.S. is frontier?
The number of people living in the frontier and the amount of land that is frontier will vary depending on the definition of frontier used. In 2011, the National Center for Frontier Communities (NCFC) asked each of the State Offices of Rural Health (SORH) to designate which of their state's counties were frontier. The SORHs designated 46% of the land area of the United States as frontier, and over 5.6 million people lived in these areas in 2010.
According to the most recent RUCA codes, in 2010 9.9 million people lived in a census tract with a RUCA code of 10, which is assigned to the most isolated, small rural census tracts. If using Frontier and Remote (FAR) area code methodology, 12.2 million people were living in level 1 territory — the least restrictive frontier delineation, and 2.3 million resided in level 4 — the most restrictive delineation. Please refer to the FAR maps above to see the land area covered by each FAR level.
RHIhub's map, Frontier Counties, displays the location of frontier counties nationwide with data from the U.S. Census Bureau based on the simple definition of fewer than seven persons per square mile.
How can I find out if my county is a frontier county?
There are several answers to this question depending on which definition you select or are required to use.
You can determine if your county meets the
fewer than seven people per square mile definition of frontier
by using the U.S. Census Bureau
QuickFacts. Start typing in your county's name, then select it from the list that appears. Scroll down
to the Geography section near the bottom of the page and look for
Population per square mile.
The Am I Rural? tool on the RHIhub website can be used to help determine whether a specific location is considered rural based on various definitions of rural, including the FAR and RUCA definitions.
You can also download the Frontier and Remote (FAR) Area Codes data files from the USDA's Economic Research Service website. FAR codes classify the most rural geographic locations in the United States using 2010 U.S. Census.
What are some of the healthcare challenges in frontier areas?
Access to healthcare
Frontier areas face the same difficulties as other rural areas in maintaining their healthcare workforce. These thinly populated regions cannot easily compete with the wages and amenities offered to healthcare professionals by hospitals and clinics in metropolitan areas. Even communities that do have adequate staffing are often one doctor or nurse away from a shortage. For more information, see RHIhub's Topic Guides: Rural Healthcare Workforce and Recruitment and Retention for Rural Health Facilities.
Many frontier counties do not have a hospital. Frontier counties that do have hospitals may face higher costs than non-frontier hospitals, due to the lower volume of patients served. In addition, frontier counties without hospitals are often clustered together, compounding the distance residents must travel to reach a hospital.
Some areas must cope with seasonal variations in healthcare needs when the population surges with tourists, seasonal workers, or retirees. The limited health resources available in frontier areas, including volunteer health services and costly medical evacuation services, may be required to care for seasonal residents, further restricting the resources available for permanent residents.
Other barriers to accessing healthcare in frontier areas include limited or unavailable public transportation options for low-income households, the elderly, and people with disabilities. Seasonal travel barriers can occur due to obstructions such as snow, ice, and flooding. Some island residents and residents of roadless areas are limited to air or boat transport to healthcare and for emergency medical transport. These areas are particularly dependent on fair weather conditions.
Health Risk Factors
Rural communities are at higher risk for substance abuse, suicide, motor vehicle fatalities, obesity, cigarette smoking, and death from unintentional injuries. While many studies have identified health disparities for all rural communities, fewer have focused specifically on the remote rural areas of the frontier. According to a 2014 article in the Journal of Rural Mental Health, mental and behavioral health providers have recognized problems of substance abuse and domestic violence as significantly more prevalent in frontier areas.
Traffic fatalities are also a risk factor for frontier residents due to poor infrastructure, such as narrower roads with bidirectional traffic. In addition, the increased time to receive emergency services and to reach a hospital capable of treating severe trauma in frontier areas contribute to the fatality rate of frontier residents.
The economy in frontier areas is often based on a few specific industries such as farming, ranching, tourism, logging, and mining. These industries, other than tourism, are associated with higher numbers of unintentional injuries, elevating the need for accessible healthcare, emergency medicine, and emergency medical transportation.
Are there funding or reimbursement advantages to being considered a frontier area?
Most of the programs that frontier areas can access for grants and enhanced reimbursement are available through shortage designations, including the Health Professional Shortage Area (HPSA) and Medically Underserved Area (MUA) designations, rather than through a designation as a frontier area. However, the Health Center Program gives special consideration to sparsely populated or frontier areas.
The National Center for Frontier Communities has highlighted frontier provisions of the Affordable Care Act (ACA) including a clause that provides protections to hospitals and physicians in eligible frontier states by establishing a floor on the Medicare wage adjustment factor and practice expense index. Eligible states are defined as all states in which at least 50% of counties have an average population density of six people per square mile or fewer. Currently, states that meet these criteria are Alaska, Montana, Nevada, North Dakota, South Dakota and Wyoming.
Frontier communities are rural, and therefore qualify for many rural-specific health-related funding programs, such as the Federal Office of Rural Health Policy's Rural Health Care Services Outreach Grant Program and Rural Health Network Development Grant Program. For additional funding programs available to frontier and other rural areas, please see RHIhub's Funding section.
What types of models are being tried to address frontier healthcare issues?
The American frontier is diverse and dynamic, and providing healthcare to residents of the frontier is often challenging. The Critical Access Hospital was one of the first innovations in provider type for rural areas, designed to preserve and sustain essential healthcare services.
A current demonstration entitled
Frontier Community Health Integration Project, or FCHIP, is a
frontier-specific program which is testing new service delivery and reimbursement models. This program
implements waivers of certain Medicare policies for Critical Access Hospitals in three specific areas:
telehealth, nursing facility care, and ambulance services. It implements these waivers at ten Critical Access
Hospitals in the frontier states of Nevada, North Dakota, and Montana. More information can be found at Frontier
Community Health Integration Project Demonstration on the CMS.gov website. Also, RHIhub's Testing New
Approaches section provides additional information about the Frontier Community Health
Many frontier areas, particularly in Alaska and remote frontier regions, do not have nearby hospitals. The Frontier Extended Stay Clinic (FESC) was a Medicare payment demonstration designed to show that enhanced reimbursement could spur the development of limited observation services (up to 48 hours) in frontier clinics, that such services could be delivered safely, and that they ultimately save payers money, primarily by avoiding costly transportation to a higher level of care. The five demonstration clinics were all isolated, fairly large, and sophisticated outpatient clinics: 4 Federally Qualified Health Centers (FQHCs) and 1 Rural Health Clinic (RHC). All of the clinics successfully met the federal conditions of participation, and demonstrated costs savings, patient safety, and patient satisfaction. However, the start-up cost was a significant factor, particularly in meeting the enhanced life-safety code requirements. A final report on the demonstration, Evaluation of the Medicare Frontier Extended Stay Clinic Demonstration: Report to Congress, provides key findings from the project. The FESC may be a model for communities that are struggling to maintain inpatient services, allowing communities to preserve primary care, emergency services, and observation services. More information on the model is available from the RHIhub's Testing New Approaches: Frontier Extended Stay Clinics.
What types of innovative ideas have been used to address healthcare workforce issues in frontier areas?
Community Health Aides (CHAs)
In Alaska, Community Health Aides (CHAs) provide healthcare in remote areas of Alaska under the supervision of a physician. CHAs work in more isolated locations and rely on telemedicine and other electronic means of communication with physicians to facilitate the care given to patients. CHAs work with a variety of patients and conditions that include mental health, trauma, and chronic disease. Some CHAs work as itinerants and travel to several communities to provide healthcare services.
Basic training for Community Health Aides can take 14 months or more, and includes both classroom time and clinical practice. For more information see the Community Health Aide Program website.
Behavioral Health Aides (BHAs)
Several states have developed Behavioral Health Aide (BHA) models that provide a variety of behavioral health services depending on the needs of the community or the state. Models include BHAs working as care coordinators, health case managers, and community support workers. Some BHA programs may require a bachelor's degree or an associate's degree while other programs may require a high school diploma. For additional information, see Behavioral Health Aides - A Promising Practice for Frontier Communities.
Dental Health Aide Therapists (DHATs)
A similar model to the CHA is the Alaska Dental Health Aide Therapist (DHAT) program. DHATs train for two years in a post-high school primary care curriculum that incorporates preventive and clinical strategies for providing oral healthcare in Alaska communities where they live.
Dental Therapists (DTs)
Several states have authorized the licensure of Dental Therapists (DTs) in an effort to address dental access issues. These midlevel providers work under the supervision of a dentist and may provide education, dental therapy, and dental hygiene services. For additional information, see Dental Therapists – A Promising Practice for Frontier Communities.
Recruitment and Retention Strategies
Various types of recruitment and retention strategies have been used to address the significant shortages of health professionals often found in frontier areas. The FORWARD NM: New Mexico's Pathways to Health Careers workforce program seeks to improve the supply and distribution of healthcare professionals through community and academic educational partnerships that include school-based health career clubs, MCAT preparation, and rural clinical internships and rotations.
Some states with large frontier designated areas provide a rural health profession tax credit for healthcare professionals who work in a rural or underserved area. New Mexico offers the Rural Health Care Practitioner Tax Credit and Oregon offers the Rural Practitioner Tax Credit for MDs, DOs, DPMs, NPs, PAs, and CRNAs.
Telehealth may be one of the most important developments to positively address healthcare workforce issues in frontier areas. Patients in frontier areas can receive healthcare, including specialty care, more locally, reducing the need to travel long distances to receive healthcare services. With telehealth technology, primary healthcare providers have the opportunity to work with specialists to provide more specialized care. Telehealth has the potential to enhance the quality of care, improve health outcomes, and reduce healthcare costs in both rural and frontier areas. However, telehealth implementation has not been consistent throughout these areas and significant regulatory issues still need to be resolved in many states. In spite of these issues, the practice of telehealth has been increasing and is improving the availability of services in many frontier regions. For additional information about telehealth, see Telehealth Use in Rural Healthcare.
