The archive of available data is subdivided in two macro areas: ecological data and individual data. The individual data, for every country prospected, are distinguished between national and international data.

The list of available data can be consulted through a search engine which allows an high detailed level of meta-information demands. It will be possible to obtain directly on-line, besides some methodological notes, the questionnaire of survey (for the individual data) or the variables list (for ecological data) as well for quite all data sets researched.
Moreover, it is activated an experimental session dedicated to the qualitative data.
