Abstract
The topic of immigration is attracting more and more attention also from the methodological point of view due to elusiveness and anonymity difficulties. Some results on a suitable sampling technique (Blangiardo 1996) and on the problem of estimating the mean of a quantitative characteristic of interest (Statistica LXIII 3:537–560, 2003) are almost consolidated nowadays. Yet the estimate of a parameter referring to a small sub-population is still open. In such a context the presence of rare domains calls for an eligible composite estimator. The present paper proposes some point and region composite estimates for the proportion and makes a comparison between them via a simulative study based on real data.
