Initiated by Directorate-General for Regional Policy and Eurostat the project “Urban Audit” was launched in 1999 to improve the economic and social cohesion in the European Union and thereby reduce the disparities between regions.

The Urban Audit is a collection of quantitative information on the quality of life in European cities. The domains covered by the collected variables include: population, housing structure, health, labour market, education and training, economic activity, environment, transport, culture and leisure.

The demographic threshold required by Eurostat is 50 000 inhabitants. The Urban Audit collection 2009-2010 plans an « exhaustive Urban Audit » project and an « annual Urban Audit » project. The City of Luxembourg participates in the “Urban Audit”

The Communication Cluster Luxembourg, Metz, Saarbrücken, Trier, abbreviated to “QuattroPole”, is a network of neighbouring towns whose aim is to promote the Greater Region by common projects.
