Knowledge discovery for inferring the usually resident population from administrative registers

Abstract

ABSTRACT From 2018 onward, the population census in Italy will leave the traditional “door-to-door” enumeration for a “register-based” system combining administrative data and surveys. An integrated system of registers makes it possible to identify patterns and groups among huge amounts of administrative data. The Italian National Institute of Statistics (Istat) carried out a trial to compute the usually resident population by using administrative data and identify patterns, leading to classify individuals and constitute groups, in order to prepare the register-based census.
