Classification of NUTS 2 Regions into: Core, Adjacent, Periphery, and Island Periphery

Description of Area Types

Core

1 C = a single city region

2 C₁ = multiple city region with no employment in agriculture

3 C₂ = contains one or more urban area’s (UA) with a population density ≥ 2 thousand / km²

4 C₃ = contains one or more urban area’s with a population density ≥ 1 thousand / km²

5 C₄ = contains one or more urban area’s with a population density ≥ 500 / km²

6 C₅ = a single national urban area with a population density (PD) < 500 / km²

Adjacent

7 A = any adjacent region which completely surrounds a core region

8 A₁ = any region adjacent to a core with one or more UA’s with a PD between 100 - 500 / km²

9 A₂ = any region adjacent to a core with one or more UA’s with a PD between 50 - 99 / km²

10 A₃ = any region adjacent to a core with one or more UA’s with a PD less than 50 / km²

pERipHERY

11 P₁ = a region bordering on an adjacent or other periphery with one or more UA’s with PD ≥100 / km²

12 P₂ = a region bordering on an adjacent or other periphery with one or more UA’s with PD ≥ 50 / km²

13 P₃ = a region bordering on an adjacent or other periphery with one or more UA’s with PD ≥ 20 / km²

14 P4 = a region bordering on an adjacent or other periphery with one or more UA’s with PD < 20 / km²

isLAND pERipHERY

15 iP₁ = a peripheral island region with one or more UA’s with a PD ≥100 / km²

16 iP₂ = a peripheral island region with one or more UA’s with a PD ≥ 50, / km²

17 iP₃ = a peripheral island region with one or more UA’s with a PD between 20 - 49 / km²

18 IP₄ = a peripheral island region with one or more UA’s with a PD < 20 / km²
