Introduction
Trying to define what "rural" is, in a nation of such diverse geography, can be a daunting task; and one's concept of the term can be a bit ambiguous and vague. Particularly, in this age of instant communication, when a Montana rancher can access the New York stock market quotes from his laptop - miles from the nearest town - defining rural becomes more of a subjective term than what is defined by Webster's. However, for those concerned with rural health care and human services, that which constitutes rural must not be subjective, but rather precise in fulfilling the definition. Federal and state policy makers, as well as service providers and researchers, need a clearly stated definition that is current in its interpretation.
The United States Census Bureau has taken the lead in creating a working definition of rural by defining what is urban or metropolitan, then defining rural by exclusion. The Bureau defines an urbanized area (UA) as consisting of adjacent, densely settled census block groups (BGs) and census blocks that meet minimum population density requirements along with adjacent densely settled census blocks where together they encompass a population of at least 50,000 people. Urban clusters (UC) have a similar definition, however, the overall population can be 2,500 to less than 50,000. The Census Bureau defines all other areas as rural. The Office of Management and Budget (OMB) defines metropolitan statistical areas - or metro areas - as central (core) counties with one of more urbanized areas, and outlying counties that are economically tied to the core counties as measured by work commuting. In 2003 the OMB added the micropolitan statistical area - micro area classification to identify a nonmetro county with an urban cluster of at least 10,000 persons or more. Noncore counties are neither micro or metro. Agencies outside of OMB often designate nonmetro counties as being rural or small town. For additional clarification see the FAQ: What are the principal differences between these definitions created by these agencies?
While the U.S. Census Bureau and the OMB are striving for more precise definitions to fit new programs, the demographics of the United States are constantly changing. The number of rural counties fluctuates over time, and disparities with old designations continually exist. The need for a clearer definition to meet the needs of new programs and new policies has encouraged other agencies to create more detailed definitions such as found in the collaboration between the WWAMI Rural Health Research Center and the Economic Research Service of the USDA. Their combined efforts permit the identification of rural areas within metropolitan designated counties. Agencies involved with rural health and human services will continue to evolve and adapt themselves, striving to better serve the needs of the rural population, for what is rural today will most likely change as we move on into the new millennium.

Terms & Acronyms
Block Group (BG) A cluster of census blocks having the same first digit of their four-digit identifying numbers within a census tract; for example, BG 3 within a census tract includes all census blocks numbered from 3000 to 3999.
Borough A legally established geographic entity in Alaska, which the Census Bureau treats as statistically equivalent to a county in other states; a minor civil division in each of the five counties that comprise New York city; a type of incorporated place in Connecticut, New Jersey, and Pennsylvania.
Census Area A statistical entity that serves as the equivalent of a county in Alaska. Census areas are delineated cooperatively by the state of Alaska and the U.S. Census Bureau for the purpose of presenting census data for the portion of Alaska not within an organized borough, city and borough, or municipality.
Census Block A subdivision of a census tract, a block is the smallest geographic unit for which the Census Bureau tabulates 100-percent data. Many blocks correspond to individual city blocks bounded by streets, but blocks -- especially in rural areas - may include many square miles and may have some boundaries that are not streets. The Census Bureau established blocks covering the entire nation for the first time in 1990. Previous censuses back to 1940 had blocks established only for part of the nation. Over 8 million blocks are identified for Census 2000.
Central Place The core incorporated place(s) or a census designated place of an urban area, usually consisting of the most populous place(s) in the urban area plus additional places that qualify under Census Bureau criteria. If the central place is also defined as an extended place, only the portion of the central place contained within the urban area is recognized as the central place.
Economic Research Service (ERS) Economic Research Service is a subdivision of the U.S. Department of Agriculture concerned with the economics of food, farming, natural resources, and rural America.
Frontier Isolated rural area, sometimes defined as having a population density of six or fewer people per square mile. Other commonly used definitions may also consider distance to services and travel time.
Health Professional Shortage Area (HPSA) Geographic regions that have shortages of professionals working in primary medical care, dental or mental health care. HPSAs may be urban or rural areas, population groups or medical or other public facilities. Geographically, HPSAs can be cities or towns, counties or groups of counties. HPSA designations are reviewed and revised annually by the Secretary of Health and Human Services based on criteria set forth in the Public Health Service Act.
Health Professional Shortage Area - Primary Care (HPSA - Primary Care) HPSA designation for a shortage of primary care health professionals that meets three requirements. First, the area must be a rational area for delivery of primary medical care services. Second, the ratio of population to existing providers must meet or exceed 3,500 people to every single provider or meet or exceed a ratio of 3,000 to 1 and have an unusually high level of need. Lastly, the area under consideration must have primary medical care professionals in continuous (nearby/adjoining) areas that are over utilized, excessively distant or inaccessible.
Initial Core One or more contiguous census block groups (BGs) that have a total land area less than two square miles and a population density of at least 1,000
people per square mile (ppsm). If no qualifying census BG exists, one or more contiguous census
blocks that have a population density of at least 1,000 ppsm.
Medically Underserved Area (MUA) Medically Underserved Areas (MUAs) are federal designations derived from the Index of Medical Underservice (IMU). This index ranges from 0 to 100 and is based on four criteria: 1) ratio of primary medical care physicians per 1,000 people, 2) infant mortality rate, 3) percent of the population with incomes below the poverty level and 4) the percent of the population age 65 or older. An IMU of 62.0 or less qualifies an area to be designated a MUA. Geographic areas designated as MUAs can be a whole county or a group of contiguous (adjoining) counties, minor civil divisions (MCD), census county divisions (CCD) or census tracts.
Medically Underserved Population (MUP) A federal designation that is derived by using the Index of Medical Underservice (IMU). This index ranges from 0 to 100 and is based on four criteria: 1) ratio of primary medical care physicians per 1,000 people, 2) infant mortality rate, 3) percent of the population with incomes below the poverty level and 4) the percent of the population age 65 or older.
Metropolitan Statistical Area or Metro Area A central, or core county, with one or more urbanized areas (see Urbanized Area), a population of at least 50,000 residents, and it may include outlying counties that are economically tied to the core counties as measured by work commuting. Outlying counties are included if 25 percent of workers living in the county commute to the central counties, or if 25 percent of the employment in the county consists of workers coming out from the central counties - the so-called "reverse" commuting pattern.
Micropolitan Statistical Area or Micro Area Any nonmetro county with an urban cluster of at least 10,000 persons or more, but less than 50,000 persons. It is further defined as the central county of a micro area. As with metro areas, outlying counties are included if commuting to the central county is 25 percent or higher, or if 25 percent of the employment in the outlying county is made up of commuters from the central county.
Noncore County A county that is neither in a Metropolitan Statistical Area or a Micropolitan Statistical Area.
Nonmetropolitan Area or Nonmetro County A county that is not located in a Metropolitan Statistical Area (MSA). Micropolitan Areas and Noncore Counties are both designated as Nonmetropolitan areas.
Population Density Total population or number of housing units within a geographic entity (for example, United States, state, county, place) divided by the land area of that entity measured in square kilometers or square miles. Density is expressed as both "people (or housing units) per square kilometer" and "people (or housing units) per square mile" of land area.
Rural The U.S. Census Bureau defines rural areas as all territories outside of Urbanized Areas (see Urban Area) and Urban Clusters (see Urban Cluster).
Rural-Urban Commuting Areas (RUCAs) A Census tract-based classification scheme (and a ZIP code-based alternative version) that utilizes the standard Census Bureau's urban area and place definition in combination with work commuting information to characterize all of the nation's Census tracts regarding their rural and urban status and functional relationships. Under the RUCA definition, types of rural and urban are defined by their city/town type and the portion of the populations that work commute from rural to urban areas.
Rural-Urban Continuum Codes A classification scheme that distinguishes metropolitan counties by the population size of their metro area, and nonmetropolitan counties by degree of urbanization and adjacency to a metro area or areas.
Rurality The quality or state of being rural, and a rural characteristic or trait.
Urban All territory, population and housing units in urbanized areas and in places of more than 2,500 persons outside of urbanized areas. "Urban" classification cuts across other hierarchies and can be in metropolitan or non-metropolitan areas.
Urban Cluster (UC) A densely settled area that has a census population of 2,500 to 49,999. A UC generally consists of a geographic core of block groups or blocks that have a population density of at least 1,000 people per square mile, and adjacent block groups and blocks with at least 500 people per square mile. A UC consists of all or part of one or more incorporated places and/or census designated places; such a place(s) together with adjacent territory; or territory outside of any place.
Urban Influence Codes (UICs) A set of 12 county-level urban influence categories developed by the Economic Research Service based on population and commuting data from the 2000 Census of Population that captures some differences in economic opportunities.
Urbanized Areas (UA) An area consisting of a central place(s) and adjacent territory with a general population density of at least 1,000 people per square mile of land area that together have a minimum residential population of at least 50,000 people. The Census Bureau uses published criteria to determine the qualification and boundaries of UAs.
ZIP Code Tabulation Areas (ZCTAs) A statistical entity developed by the U.S. Census Bureau for tabulating summary statistics from Census 2000 to facilitate defining the land area covered by each ZIP Code.
