In sample surveys, a sample drawn from a subpopulation is not always large enough to yield reliable estimates based solely on data from that subpopulation. This occurs, for example, when the subpopulation is not accounted for in survey planning or when estimates at a very low administrative level of the survey population are required. This chapter provides a summary of Small Area Estimation (SAE), a statistical method for obtaining reliable estimates at the sub-population level. The main approaches to SAE are described, with emphasis on their differences and applications.     «
