The use of Administrative Data to Produce the First Wave of Italian Permanent Census Estimates

25 March 2021

All are invited to this webinar, organised by the International Association for Survey Statisticians.

In 2016 Istat (Italian National Statistical Institute) launched a modernization programme in which the Registers Integrated System (RIS) became the backbone of the data production process. Starting from 2018, the Istat, like other countries (ONS, 2016), launched the Permanent Census, a new census system, aimed at integrating administrative data and data coming from sample surveys to obtain the counts of the usual resident population at a reference date, cleating Census counts of coverage errors affecting the register. A Lincoln-Petersen estimator is used after adjusting for people erroneously included in the register (overcoverage) or missed by the registers (undercoverage) on the basis of record linkage procedures and an evaluation of the not response errors which affect the surveys by means of the administrative signals of work and school enrolment (signs of administrative lives).
