Functional Urban Area: what is it?
A Functional Urban Area is defined by OECD as a functional economic unit characterized by densely inhabited “urban cores” and “hinterlands” whose labor market is highly integrated with the cores (at least 15% of their employed residents working in a certain urban core)
This definition provides a spatial delimitation beyond administrative borders which is relevant for a multitude of thematic fields (transport, social aspects, economy,accessibility,..)
