During the last 20 years illegal immigration has become a key problem in Italy and the interest of public agencies in surveying immigrant population has consequently grown. The immigrant population is difficult-to-sample since exhaustive lists or frames are generally unavailable and units usually demand to remain anonymous so that the customary units’ identification by a label is not allowed. Center sampling is a strategy recently developed in Italy for surveying immigrant population by addressing both the concerns “how to reach units for interviewing?” and “how to estimate parameters of interest?”. Estimation of the mean of a quantitative variable is considered.

Abstract
During the last 20 years illegal immigration has become a key problem in Italy and the interest of public agencies in surveying immigrant population has consequently grown. The immigrant population is difficult-to-sample since exhaustive lists or frames are generally unavailable and units usually demand to remain anonymous so that the customary units’ identification by a label is not allowed. Center sampling is a strategy recently developed in Italy for surveying immigrant population by addressing both the concerns “how to reach units for interviewing?” and “how to estimate parameters of interest?”. Estimation of the mean of a quantitative variable is considered.
