3.1. Data description | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Data and metadata are transmitted to Eurostat by the Member States in the framework of the Unified Demographic Data Collection which is in accordance with Regulation (EC) No 862/2007 and Regulation (EU) No 1260/2013 and their implementing regulations. This Euro SDMX Metadata Structure is used for the purpose of quality reporting. The definition of the quality concepts and guidelines are described in the European Statistical System Handbook for Quality Reports. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
3.2. Classification system | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The regional breakdown of the Member States in the regional demographic tables is done under the most recent NUTS classification. There are agreements between Eurostat and Candidate countries as well as between Eurostat and EFTA countries, for which statistical regions have been coded in a way that resembles NUTS. For more information on the versions in force, please see: https://ec.europa.eu/eurostat/web/nuts/. |

14.1. Timeliness | |||
According to Article 4 (2) of the Commission Implementing Regulation (EU) No 205/2014, each year Member States shall provide the Commission (Eurostat) with data at national and regional level as described in Annex II and related standard reference metadata ( In the metadata structure definition defined for the Euro SDMX Metadata Structure) for the reference year within 12 months of the end of the reference year. According to Article 3 (2) of the Commission Regulation (EC) No 862/2007, Statistics on international migration, usually resident population and acquisition of citizenship shall be supplied to the Commission (Eurostat) within 12 months of the end of the reference year. Most data on vital events are available the year following the event. However, some births and deaths, especially if they took place outside the country, can be registered with some delay. |
|||
14.2. Punctuality | |||
Data are recorded with good punctuality in the registers and delivered by the various administrations to the FSO, via a secured IT line, according to planification. |

15.1. Comparability - geographical | ||||||||||||||||||||||||||||
Data cover the whole of Switzerland and are completely comparable between geographical areas. |

15.2. Comparability - over time | ||||||||||||||||||||||||||||
|
||||||||||||||||||||||||||||
15.3. Coherence - cross domain | ||||||||||||||||||||||||||||
Data are coherent. The use of a unique personal identifier (the social insurance number) in all data sets allows for record matching during the production of the data and the correction of any incoherence. Incoherence concerning residence permit statistics can only occur between data delivered by the Federal Statstical Office and data eventually delivered by State Secretariate for Migration, but not in the data from one same institution. Additional information according to the letter/email from 30 October 2018: — The differences between Residence Permits Statistics and International Migration Statistics: |

15.4. Coherence - internal | ||||||||||||||||||||||||||||
Data are coherent. The use of a unique personal identifier (the social insurance number) in all data sets allows for record matching during the production of the data and the correction of any incoherence. |
|
|||
No direct burden on respondents for data extracted from registers. A very small burden for citizens by completing register data with a diversity of thematical enquiries. However, reaching for a very small part of population (for example structural survey: annually 200 000 citizens). |

18.1. Source data | ||||||||||||||||||||||||||||
|
||||||||||||||||||||||||||||
18.2. Frequency of data collection | ||||||||||||||||||||||||||||
Data on population stock and migration are collected quarterly, data on vital events are collected daily. |
||||||||||||||||||||||||||||
18.3. Data collection | ||||||||||||||||||||||||||||
Register-based data: — A special law was passed to define the minimum content of the already existing registers of persons: the Federal Act of 23 June 2006 on the Harmonisation Register of Residents and of other Official Registers of Persons (CC 431.02. See also the Ordinance on Register Harmonisation of 21 November 2007, CC 431.021). It also addresses the transmission of data to the FSO, the legal obligations regarding registration, the delays in reporting, etc. — Vital events are registered in the system Infostar of the Federal Civil Registry Office, according to the Ordinance on Civil Status of 28 April 2004 (CC 211.112.2). For information: https://www.bj.admin.ch/bj/de/home/gesellschaft/zivilstand.html (German); Persons can be registered in several registers, so during processing the FSO links the records with the help of a unique personal identifier (the social insurance number). — Annual structural survey. |
||||||||||||||||||||||||||||
18.4. Data validation | ||||||||||||||||||||||||||||
Absolute figures received from the administrative registers are validated by the FSO before being processed and disseminated. Data validation takes place at several levels of data processing, and involves checking rules and data cross validation. Checking rules refer to the fulfilling of the restrictions imposed to the value of a data item in order to consider data as correct. If data are not plausible, the data provider is contacted for clarifications. Cross validations are carried out to check data consistency between the different tables. The last step of data validation refers to data and demographic indicators consistency over time. |
||||||||||||||||||||||||||||
18.5. Data compilation | ||||||||||||||||||||||||||||
Net migration – the difference between the number of immigrants and the number emigrants during the year (net migration is therefore negative when the number of emigrants exceeds the number of immigrants). |
||||||||||||||||||||||||||||
18.6. Adjustment | ||||||||||||||||||||||||||||
Data are not adjusted. |
