Community and economic development practitioners working in rural places often run into a deceptively simple problem before they ever pick a strategy, write a grant, or define a service area: deciding what counts as “rural” in the first place.
It seems like it should be straightforward. We all know rural when we see it, right? The trouble is that “rural” is doing a lot of work. It determines program eligibility, shapes which tools are considered appropriate, frames how outcomes get evaluated, and influences whether a community is treated as a candidate for growth, stabilization, or preservation. A definition that quietly shifts from one federal agency, foundation, or program to the next is not a technicality; it is the gate through which resources do or do not flow.
A surprisingly common situation in rural practice is that the same community gets classified differently depending on which federal measure is consulted. Recent block-group-level analysis documents cases where a place is simultaneously labeled “rural” by the Census Bureau and “metro” by USDA’s Rural-Urban Continuum Codes (RUCC), or labeled “metro” by RUCC while sitting in a sparsely populated desert region with little access to essential services (Nelson and Nguyen, 2023). The reverse happens too: communities classified as completely rural under census definitions can in practice have strong access to supermarkets, schools, healthcare, and other services because they are densely settled in a small footprint.
For practitioners, this is not a curiosity. It means that two grant programs in the same fiscal year, both targeting “rural” communities, can produce different eligibility maps for the same set of jurisdictions. It also means that the same community can be told it is too rural for one set of resources and not rural enough for another. Knowing which definition a particular program uses — and why — is part of the basic due diligence of rural community development work.
This discussion builds on an earlier post in this series and takes a step back from rural community development practice to think about what we actually mean when we attach the word “rural” to it, and why getting that framing right matters for the day-to-day work.
The Definition Problem: Years of Inconsistency
Some policymakers define rural by economic composition (agriculture, extraction), some by what it lacks (services, density, urban proximity), some by population thresholds that range from 10,000 to 50,000, and some by social characteristics like community norms, identity, and cohesion.
The implication for practice is concrete: two programs can both target “rural” North Carolina and end up serving meaningfully different sets of communities. A program tied to the Federal Office of Management and Budget (OMB) metropolitan/non-metropolitan status will draw a very different map than one tied to USDA’s Rural-Urban Continuum Codes (RUCC), Rural-Urban Commuting Area (RUCA) codes, a population threshold, or a state-defined tier system.
The Most Common Rural Definitions, and Their Trade-Offs
Practitioners will encounter at least five common ways “rural” gets operationalized. Each has trade-offs worth knowing.
- OMB Metropolitan/Non-Metropolitan Status. Widely used, easy to apply, and aligned with many federal funding streams. Under this definition, rural communities are those that are not in a metropolitan statistical area (MSA). This is a binary measurement strategy, and it treats a small town adjacent to a large MSA the same as a remote, sparsely populated jurisdiction far from any urban core.
- Point for practice: The OMB Metropolitan Determination is used to establish Medicare hospital payment rates and to determine eligibility for special rural hospital designations like Critical Access Hospital status, which affects both Medicare and, in many states, including NC, Medicaid reimbursement.
- USDA (RUCC) and RUCA Codes. More gradated than OMB, capturing degrees of rurality based on population, urbanization, and commuting patterns. RUCC operates at the county level; RUCA at the census tract level. Both are useful, but they work at scales that don’t always match how cities and towns are organized. RUCC classifies whole counties; RUCA classifies census tracts. So a county can be labeled rural even when it includes a city of tens of thousands of people, which hides real differences within that county.
- Point for practice: Rural health grants from the Health Resources & Services Administration (HRSA) use a hybrid of OMB county status and RUCA codes as eligibility criteria.
- Population Thresholds. Simple and intuitive, but the chosen cutoff (2,500? 10,000? 50,000?) is largely arbitrary and rarely justified. Two communities just above and below the threshold are treated as fundamentally different when they likely are not.
- Point for practice: USDA Rural Development Loans and Grants use the population thresholds as part of their eligibility criteria.
- OECD Functional Urban Areas and Density-Based Typologies. Useful for international comparison and built around a population density threshold (often below 150 inhabitants per square kilometer, or in the metric system, approximately 390 people per square mile). Rarely used in U.S. practice but increasingly relevant for cross-national learning.
- Composite or Asset-Based Indices. Newer approaches attempt to capture multiple dimensions of rurality at once. The Community Assets and Relative Rurality (CARR) index, for example, builds a continuous, block-group-level measure for the entire U.S. that combines traditional remoteness and density indicators with the availability of and access to community assets — supermarkets, schools, banks, healthcare facilities, recreation, and other services and amenities (Nelson and Nguyen, 2023). They are also built at finer spatial resolutions than county-level measures, which matters in North Carolina, where the state’s tier system operates at the county level and can mask important rural variation within counties.
None of these is “correct” in the abstract. The right definition depends on the question being asked. A workforce program serving regional commuters might reasonably rely on RUCA codes. A small water system technical assistance program might rely on population thresholds. A regional collaboration initiative might lean on local government density or proximity to peer jurisdictions.
To make these trade-offs easy to visualize, I built an interactive North Carolina Rurality Explorer that lets users compare how counties and census tracts are classified under different rural definitions. It is a useful starting point for conversations about which definition fits a given program or planning effort.
Why Definitional Choices Matter for Practice
Three practical consequences follow from how rural is defined.
First, eligibility shifts with the definition. A community might qualify as rural under a state housing program but not under a federal broadband program, or vice versa. Practitioners helping clients navigate funding stacks should not assume that “rural” carries the same meaning across programs.
Second, strategy design follows from how a place is categorized. Communities classified primarily as “non-metropolitan” tend to be slotted into preservation- or stabilization-oriented programs. Communities classified through more nuanced typologies that recognize within-rural variation are more likely to be matched with strategies suited to their actual trajectory — whether that is repositioning, growth, or asset-leveraging.
Third, evaluation depends on what we compare against. If “rural” is operationalized as the negative of urban, then rural outcomes will tend to look like deficits relative to urban benchmarks. If “rural” is operationalized as a distinct context with its own asset profile, then evaluation can attend to outcomes that matter within rural settings — civic infrastructure, social capital, regional collaboration capacity — that often do not register in urban-anchored frameworks.
A Working Definition for Rural Community Development
Rather than waiting for the policymakers to settle on a single definition, practitioners can adopt a working approach that travels well across programs and contexts. Rural community development is most usefully understood as:
Community development is practiced in places characterized by some combination of low population density, geographic isolation from urban cores and major transit infrastructure, limited proximity to peer local governments, and constrained availability of or access to essential services and amenities, and is shaped by distinct cultural, historical, and institutional contexts that influence how strategies are designed, delivered, and received.
This definition does three things at once. It anchors rural community development in the broader field rather than separating it. It identifies the structural conditions (density, isolation, proximity, asset access) that shape capacity and strategy. And it leaves room for the cultural and historical dimensions that vary substantially across North Carolina’s mountain, piedmont, and coastal regions.
Closing Thought
Definitions are not just academic. They shape who gets served, what gets funded, and how success is measured. When a program description says “rural,” the next question worth asking is which rural? — followed by does this definition fit the community in front of me, and does it fit the work we are trying to do?
Rural community development belongs squarely within the broader community development field. What makes it distinct is not a different theory of change but a different operating environment that calls for explicit, defensible choices about how rurality is defined, measured, and used.
