Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

3.1. Data description
First results on the main demographic developments in the year of reference.
Total yearly survey on resident population.
Yearly survey on population change and stock at municipality level, providing information by sex on: live births, deaths, registration and deregistration for migration and the number of resident population at the end of the year.
3.2. Classification system
Not applicable.
3.3. Coverage - sector
Not applicable.
3.4. Statistical concepts and definitions
According to Art. 9.3 of Reg. 1260/2013, Italy uses the definition of “usual resident population,” that is, the total number of persons who, at the reference date, have their usual residence in a Member State.
3.4.1. Residence definition for data sent to Eurostat
See sheet 3.4.1 in the annex at the bottom of the file.
3.4.2. National definition
See sheet 3.4.2 in the annex at the bottom of the file.
3.4.3. Deviation of national definition from the definition used in data sent to Eurostat
See sheet 3.4.3 in the annex at the bottom of the file.
3.5. Statistical unit
Number of persons.
3.6. Statistical population
See sheet 3.6 in the annex at the bottom of the file.
3.7. Reference area
Data are available only at national level of geographical detail.
3.8. Coverage - Time
See concept 5.
3.9. Base period
Not applicable.
Counts of statistical units
The reference date for population data is the end of the reference period (midnight of 31December). The reference period for vital events data is the calendar year in which the events occurred.
The reference period for migration flow data is the calendar year in which the migration occurred.
6.1. Institutional Mandate - legal acts and other agreements
This section shows the links to national methodology reports and reference metadata files available on-line concerning the supplied data.
See sheet 10.6 in the annex at the bottom of the file.
10.7. Quality management - documentation
Not available.
11.1. Quality assurance
Population change and stock data are checked before being uploaded into the database and disseminated to the public. The validation rules are established to ensure the data consistency and the comparability along times of indicators.
11.2. Quality management - assessment
Internal controls on specific items of municipal electronic forms.
12.1. Relevance - User Needs
Statistics on population change and the structure of population are increasingly used to support policy making and to provide the opportunity to monitor demographic behaviour within political, economic, social and cultural contexts.
12.2. Relevance - User Satisfaction
Not available.
12.3. Completeness
Not available.
13.1. Accuracy - overall
This section outlines the potential reasons for unreliability in data concerning population, live births, deaths, immigration, emigration and net migration.
See sheet 13.1 in the annex at the bottom of the file.
13.2. Sampling error
In case of survey as data source, this section provides information on the part of the difference between a population value and an estimate thereof, derived from a random sample, which is because only a subset of the population is enumerated.
See sheet 13.2 in the annex at the bottom of the file.
13.3. Non-sampling error
In case of survey as data source, this section provides information on the error in survey estimates which cannot be attributed to sampling fluctuations.
See sheet 13.3 in the annex at the bottom of the file.
14.1. Timeliness
Not available.
14.2. Punctuality
Not available.
15.1. Comparability - geographical
The question is not clear. Anyway National borders of Italy have been not changing since 1945.
15.2. Comparability - over time
This section provides information on the length of comparable time series (indicating the first reference year for which data are available), reference periods at which break in series occurs, the reasons for the breaks and treatments of them.
See sheet 15.2 in the annex at the bottom of the file.
15.3. Coherence - cross domain
Not available.
15.4. Coherence - internal
In this framework Italy is well inside the Usual residence definition given in article 2/d, in particular where it is stated that where the circumstances described in point (i) or (ii) cannot be established, ‘usual residence’ can be taken to mean the place of legal or registered residence.

17.1. Data revision - policy
Not available.
17.2. Data revision - practice
Not available.
18.1. Source data
This section provides a list of data sources used for the first reference year and any subsequent changes thereto, to produce data.
See sheet 18.1 in the annex at the bottom of the file.
18.2. Frequency of data collection
Annual.
18.3. Data collection
The demographic balance of the resident population is produced by elaborating micro data of the demographic dynamics obtained through the notifications sent by Municipalities to the ANPR system.
18.4. Data validation
Data validation:
Coherence control with previous data of the same survey.
Coherence control with data from other surveys or sources.
18.5. Data compilation
Data are collected by ANPR (National Register of Resident Population), through automatic notifications, and therefore no questionnaire are required.
18.6. Adjustment
The statistical adjustments will be validated in the final demographic balance, following the validation Permanent Census data, at the end of the year.
Data related to the demographic balance for the year 2025 are provisional.
Final data will be disseminated after the statistical population realignment due to the results of permanent Census.
First results on the main demographic developments in the year of reference.
Total yearly survey on resident population.
Yearly survey on population change and stock at municipality level, providing information by sex on: live births, deaths, registration and deregistration for migration and the number of resident population at the end of the year.
