Aspettando il 2011: riflessioni su qualita` e uso dei risultati del Censimento demografico

After reviewing the novel aspects characterising the last four population censuses and how researchers have exploited their results, we present some thoughts about the 2011 Italian population census. Whilst calling for more accurate and accessible contents and results of the survey, we focus our attention on the rather controversial issue regarding the procedure and mode of data acquisition. Do we need to confirm the traditional (universal and simultaneous) survey, or can we try new procedures, even if this means to combine information from administrative registries and surveys? This is a dilemma that calls for an accurate evaluation of the advantages and drawbacks related to the different hypothesis in each of the two cases. The experiences of 1991 and 2001, which included surveys of foreigners and the temporary residents, demonstrated that results do not always follow the effort and reflect the expectations. Innovations are welcome, but only if they do not compromise the quality and details of the census information gathered.
