Defining rural territory
The unit you count in changes the story you tell. The JRC's functional rural areas build rural territory around real rural centres and real drive times.
How are functional rural areas built, and why are they a better unit for rural policy than municipalities or NUTS-3 regions?
Every territory outside functional urban areas is assigned to the rural centre with the strongest pull (the largest town or village within a 10-minute drive). Small catchments are merged until each has at least 25,000 inhabitants or is more than an hour from its neighbours. The result is more even in size, gives less volatile statistics than municipalities and more detail than NUTS-3 regions.
- Comparable rural statistics need one harmonised way to delineate cities, towns and suburbs, and rural areas
- Functional rural areas cover all territory outside functional urban areas, built around rural centres
- Thresholds: 10-minute drive to a centre, at least 25,000 inhabitants or over an hour apart, centres under 30 minutes apart merged
- OECD: rural-urban partnerships work best on functional regions, not administrative borders
Defining 'rural': municipalities, regions and functional rural areas

Rural policy needs a map of where “rural” is. D2.2 (Annex H) puts the requirement plainly: reliable, timely and comparable datasets can only come from a coherent and harmonised methodology that delineates cities, urban and rural areas in a consistent manner. On that basis Eurostat compiles subnational statistics for rural areas, towns and suburbs, and cities across the EU. With this kind of delineation the EU can state that rural areas cover 83 % of its territory and hold 30 % of its population.
The unit problem
Policy data usually comes in administrative units: municipalities (local administrative units, LAU) or NUTS-3 regions. Both cause trouble for rural analysis. Municipalities vary greatly in size, so indicators such as population change jump from one to the next. NUTS-3 regions are large enough to average away the differences that matter.
Functional rural areas
A 2023 Joint Research Centre paper (Dijkstra and Jacobs-Crisioni, JRC135599), summarised in Annex E of D2.2, proposes functional rural areas (FRAs). They cover all territory outside functional urban areas and are built in three steps:
- Rural centres: the largest town or village within a 10-minute drive.
- Catchments: each population grid cell goes to the nearby centre with the greatest gravitational pull.
- Merging: small, nearby catchments are combined until each has at least 25,000 inhabitants or lies more than an hour’s drive from its neighbours. Catchments whose centres are less than 30 minutes apart are combined even when both are larger.
| Unit | Strength | Limit for rural policy |
|---|---|---|
| Municipality (LAU) | Matches local government | Statistics are volatile, units uneven in size |
| NUTS-3 region | Standard for EU statistics | Too coarse, hides local differences |
| Functional rural area | Even in size, follows daily travel | Not an administrative unit |
The paper finds that FRAs give less volatile figures for population change and distance to the nearest school than LAUs, and more detail than NUTS-3. They can inform policy on access to services, demographic change, transport investment and public transport. The method works anywhere with a population grid, a road network and functional urban area boundaries. The OECD is producing FRAs for some of its members. D2.2 reports that an update on the 2021 population grid and the census 2021 LAU boundaries was expected in 2024.
Why it matters for PoliRural+
The OECD’s work on rural-urban partnerships reaches the same conclusion from the governance side: partnerships work best on functional regions connected by flows of people and resources, not inside administrative borders. D2.2 asks every pilot to plan that way. The inputs FRAs need are open geodata, the same kind of layers behind the local GeoAI knowledge base.
