Abstract: Exposure data for buildings have been collected from different sources and for various uses. The databanks created for seismic risk assessment comply with the desired taxonomy of exposed buildings for vulnerability studies, but are often developed for specific urban areas. National censuses take place at regular time intervals and collect exhaustive information on a country’s housing stock. However, housing censuses are not completely harmonised across European countries and significant efforts are required to collect and process census data for further use in seismic risk studies. The study of this report aims at inventorying the housing stock in European countries and classifying its seismic vulnerability at a regional level. The first step was the collection of georeferenced data from the 2011 Population and Housing censuses through Eurostat, specifically, the number of dwellings by period of construction at a regional level. Subsequently, the ratio of dwellings to buildings was calculated, considering the degree of urbanisation. Finally, the dwellings were arranged in different classes of vulnerability, based on the seismic design code in force in the country in the year the dwelling was constructed. The analysis of the inventory shows that the majority of existing buildings in Europe are highly vulnerable to earthquakes. Previous case studies have shown that Eurostat data can be used to assess, with acceptable accuracy, the seismic risk at a regional level. Therefore, the inventory is suitable to be used in further studies for estimating seismic losses across Europe and for prioritising retrofitting strategies for the European building stock.
