Live births registered in the population register

Live births residing in Italy are detected on annual basis through the Survey “Live births registered in the population register” established in 1999.

Until 2018, data were collected through the compilation of Istat Model P4 operated by the Population Register Offices of Italian municipalities (survey units), and then transmitted to Istat.

As of 2020, after a transitional period, the amount of live births residing in Italy is the result of accounting for individual birth registration models in the population register, acquired through notifications sent by Italian municipalities to the ANPR (National Register of the Resident Population) system.

The information contained in the individual data enables municipal-level knowledge of the main phenomena related with live births and fertility of resident population in Italy.

With respect to the live births, the available information enables to classify births (units of analysis) according to certain characteristics of the live birth, such as: sex, name, citizenship, place of birth and residence, and, albeit indirectly, birth order and filiation (born from married or unmarried parents). Parents of the live births can be classified by age and date of birth, citizenship, type of couple (Italian, foreigner, or mixed couple) and marital status.

Live births data are available in the section from 1999 to the most recent year of publication.

Available information on live births are also used for the calculation of main fertility indicators.
