Reuse potential

20Any analysis related to European urban systems: to our knowledge this is the only open access comprehensive data base delineating urban agglomerations of all sizes above 10 000 inhabitants in a systematic way and enabling their comparison in Europe at different dates (with evolving perimeters).

21Possible deeper analysis of a specific hierarchical level (for instance demographic evolution of small urban areas) or a set of countries

23Three different databases were used in the TRADEVE project:

1. Historical Populations Data of LAU for 1961, 1971, 1981, 1991, 2001 and 2011 (see Gloersen et al. 2013, open access)

2. Urban Morphological Zones 2000, defined from the European Environment Agency (EEA) in 2004 (version v2) (see Bretagnolle et al. 2014). Open access.

3. Dictionary of correspondence LAU2/UMZ (restricted version, see Figure II 1 of the Tradeve report, https://halshs.archives-ouvertes.fr/​halshs-01311420/​document) elaborated in ESPON Database (see Bretagnolle et al. 2014). It concerns UMZ 2000 and LAU2 (2012 geometry) and gives the different LAU2 that are linked to UMZ 2000. Open access.
