EUROPOLIS is the data infrastructure for the international comparative urban research of N.U.R.E.C. It is a result from the SCECS project that was undertaken by N.U.R.E.C and a product that came out from LCSP and the Atlas of Agglomerations. EUROPOLIS supplies the necessary database for further projects and analyses of N.U.R.E.C, e.g. the production of SWOT analyses and cityrankings along different indicators. Due to the recent extension of the EU by 10 countries from Eastern European there is a growing demand for city-related data. N.U.R.E.C is going to tackle this challenges and discusses at present the opportunity to extend the data focused on Western Europ used by EUROSTAT to other areas of Europe.
