3.1. Data description
Since 2010, a new Census is conducted and evaluated on an annual basis by the Swiss Federal Statistical Office (FSO). The census consists of four separately conducted surveys, two of which have been used in the preparation of the data for the Census Hub Hypercubes – the Register Survey and the Structural Survey.
In the Register Survey, data from the local, cantonal and national population registers as well as from the national Buildings and Dwellings Register is used. It provides information on: a) persons and households such as age, sex, marital status, nationality, household size, etc.; b) buildings and dwellings such as period of construction, building category, number of dwellings, number of rooms, useful floor space etc. The Register Survey provides basic information about the entire population, buildings and dwellings; the data can be evaluated at a very detailed geographical level since for every building, metric geo-coordinates are available and a building and dwelling identifier is associated to every person in the population registers.
The Structural Survey provides information on the themes of population, households, families, housing, employment, mobility, education, language, religion and migration. The sampled population is composed of persons aged 15 or more of the permanent resident population living in private households; each year a minimum of 200'000 persons is randomly selected in order to participate in the Structural Survey. Cantons or large cities can enlarge the sample for their territory on request. Overall approximately 4% of the resident permanent population aged 15 years or older is surveyed in writing (participation by internet or by completing a paper questionnaire). The survey complements the information collected from the registers and provides additional statistics on the structure of the population. Survey results with a sufficiently high quality are available at the following geographic levels: Switzerland (NUTS 1), major regions (NUTS 2), cantons (NUTS 3) and communes (LAU 2) with more than 15’000 inhabitants.
In contrast to the Register Survey which contains information on the entire resident population, the Structural Survey is based only on the resident permanent population aged 15 years or older.
The fact that the Register Survey and the Structural Survey use different universes and are distinct by theme, leads to the situation where population totals of evaluated data vary.
If a hypercube used in the Census Hub is based on Structural Survey data then the result will be 6’587’556 persons, which corresponds to the total population aged 15 years or older and living in private households. If a hypercube is based on Register Survey data then the resulting total resident population will be 7’954’662 persons.

3.4. Statistical concepts and definitions
3.4.1. Statistical concepts and definitions - Usual residence
Usual residence means the place of legal residence, that is the main residence of the person according to the population registers, regardless of temporary absences for purposes of recreation, holidays, visits to friends and relatives, business, medical treatment or religious pilgrimage.
Persons legally resident in the place of enumeration but absent, or expected to be absent, at the time of the census for less than one year are considered as temporarily absent persons and thus included in the total legally resident population (the so-called permanent resident population). In contrast, persons living or expected to live outside the place of enumeration for one year or more are not considered temporarily absent and are therefore excluded from the total population. This is regardless of the length of visits that they may pay to their families from time to time.
Persons who are enumerated but do not meet the criteria for permanent legal residence in the place of enumeration, i.e. do not live or do not expect to live in the place of enumeration for a continuous period of at least 12 months, are considered temporarily present and are therefore not counted in the total legally resident population.
3.4.2. Statistical concepts and definitions - Sex
sex = 1 -> man
sex = 2 -> woman
3.4.3. Statistical concepts and definitions - Age
The age reached at the reference date (in completed years).
3.4.4. Statistical concepts and definitions - Marital status
Marital status is the (legal) conjugal status of an individual in relation to the marriage laws of the country (de jure status).
A person shall be classified according to his/her most recently acquired legal marital status at the reference date.
'Registered partnerships' are reported only by countries that have a legal framework regulating partnerships that:
(a) lead to legal conjugal obligations between two persons;
(b) are not marriages;
(c) prevent persons to commit themselves into multiple partnerships with different partners.
In countries where the legislation includes provisions for married partners to be 'legally separated', such 'legally separated' persons are classified under 'married'.
Rules regulating marriages are found in the Swiss Civil Code of 10 December 1907 (Status as of 1 July 2013). According to Article 94, "To be able to marry, the parties to the engagement must have reached 18 years of age and have the capacity of judgement."
The "Loi fédérale sur le partenariat enregistré entre personnes du même sexe du 18 juin 2004" (Federal law on registered partnership between persons of the same sex, Status as of 1 July 2013) regulates registered partnerships. Same-sex partners can have their partnership registered; similarly to marriage, the parties must have reached 18 years of age and have the capacity of judgement.
3.4.5. Statistical concepts and definitions - Family status
The family nucleus is defined in the narrow sense, that is as two or more persons who belong to the same household and who are related as husband and wife, as partners in a registered partnership, as partners in a consensual union, or as parent and child. Thus a family comprises a couple without children, or a couple with one or more children, or a lone parent with one or more children. This family concept limits relationships between children and adults to direct (first-degree) relationships, that is between parents and children.
Child (son/daughter) refers to a blood, step- or adopted son or daughter (regardless of age or marital status) who has usual residence in the household of at least one of the parents, and who has no partner or own children in the same household. Foster children are not included. A son or daughter who lives with a spouse, with a registered partner, with a partner in a consensual union, or with one or more own children, is not considered to be a child.
The term couple includes married couples, couples who live in a consensual union, and same-sex couples in a registered partnership. In Switzerland registered partnerships of opposite-sex couples do not exist.
Two persons are considered to be partners in a 'consensual union' when they
— belong to the same household, and
— have a marriage-like relationship with each other, and
— are not married to or in a registered partnership with each other.
'Skip-generation households' (households consisting of a grandparent or grandparents and one or more grandchildren, but no parent of those grandchildren) are included in the definition of a family.
3.4.6. Statistical concepts and definitions - Household status
Switzerland applies the 'household dwelling' concept. All persons that belong to the permanent resident population and that are living in a household unit to be members of the same household per occupied housing unit are considered under the 'household dwelling' concept. The number of housing units and the number of households occupying them is equal, and the locations of the housing units and households are identical.
The category 'Persons living in a private household' comprises 'Persons in a family nucleus' and 'Persons not in a family nucleus'. The category 'Persons in a family nucleus' comprises all persons who belong to a private household that contains a family nucleus of which they are a member. 'Persons not in a family nucleus' comprises all persons who either belong to a non-family household or to a family household without being member of any family nucleus in that household.
A non-family household can be a one-person household ('Living alone') or a multiperson household without any family nucleus. The category 'Not living alone' comprises persons that live either in a multiperson household without any family nucleus or in a family household without being member of any family nucleus in that household. Persons who belong to a skip-generation household and who are not member of any family nucleus in that household shall be classified in the optional category 'Persons living in a household with relative(s)'.
The term 'son/daughter' is defined as the term 'child' in the technical specifications for the topic 'Family status'. 'Husband/wife couple' means a married opposite-sex couple.
'Registered partnership' is defined as in the technical specifications for the topic 'Legal marital status'. 'Consensual union' is defined as in the technical specifications for the topic 'Family status'.
The category 'Partners' comprises 'Persons in a married couple', 'Partners in a registered partnership' and 'Partners in a consensual union'.
'Primary homeless persons' could not be surveyed nor estimated in Switzerland. They are persons living in the streets without a shelter that would fall within the scope of living quarters as defined in the technical specifications for the topic 'Type of living quarters'.
3.4.7. Statistical concepts and definitions - Current activity status
Current activity status' is the current relationship of a person to economic activity, based on a reference period of one week, which may be either a specified, recent, fixed, calendar week, or the last complete calendar week, or the last seven days prior to enumeration.
The 'currently economically active population' comprises all persons who fulfil the requirements for inclusion among the employed or the unemployed.
'Employed' persons comprise all persons aged 15 years or over who during the reference week:
(a) performed at least one hour of work for pay or profit, in cash or in kind, or
(b) were temporarily absent from a job in which they had already worked and to which they maintained a formal attachment, or from a self-employment activity.
The 'unemployed' comprise all persons aged 15 years or over who were:
(a) 'without work', that is, were not in wage employment or self-employment during the reference week; and
(b) 'currently available for work', that is, were available for wage employment or self-employment during the reference week and for two weeks after that; and
(c) 'seeking work', that is, had taken specific steps to seek wage employment or self-employment within four weeks ending with the reference week.
The category 'Currently not economically active' includes persons below the national minimum age for economic activity.
In ascribing a single activity status to each person, priority is given to the status of 'employed' in preference to 'unemployed', and to the status of 'unemployed' in preference to 'not economically active'.
3.4.8. Statistical concepts and definitions - Occupation
Occupation' refers to the type of work done in a job (that is the main tasks and duties of the work). Persons doing more than one job are allocated an occupation based on their main job, which is identified according to the time spent on the job or, if not available, to the income received.
The breakdown by occupation is available for persons aged 15 or over that were:
— employed during the reference week, or
— unemployed during the reference week, but have ever been in employment
Persons are classified according to the occupation they had during their most recent employment. The categories included in the breakdown 'occupation' correspond to the major groups of the ISCO-08 (COM) classification.
Persons under the age of 15 years, as well as persons aged 15 or over that were:
— not economically active during the reference week, or
— unemployed, never worked before (i.e. they have never been employed in their lives)
are classified under 'not applicable'.
The allocation of a person within the breakdowns of the topics 'Occupation', 'Industry' and 'Status in employment' is based on the same job.
3.4.9. Statistical concepts and definitions - Industry
Industry (branch of economic activity) is the kind of production or activity of the establishment (or similar unit) in which the job of a currently economically active person is located.
Persons doing more than one job shall be allocated an industry (branch of economic activity) based on their main job, which is to be identified according to the time spent on the job or (if not available) the income received.
The breakdown by industry is available for persons aged 15 or over that were:
— employed during the reference week, or
— unemployed during the reference week, but have ever been in employment
Persons are classified according to the industry they worked in during their most recent employment. The categories included in the breakdown 'industry' list the 21 sections of the NACE Rev. 2 classification and appropriate aggregates.
Persons under the age of 15 years, as well as persons aged 15 or over that were:
— not economically active during the reference week, or
— unemployed, and have never worked before (i.e. have never been employed in their lives)
are classified under 'not applicable'.
The allocation of a person within the breakdowns of the topics 'Occupation', 'Industry' and 'Status in employment' is based on the same job.
3.4.10. Statistical concepts and definitions - Status in employment
An 'employee' is a person who works in a 'paid employment' job, that is a job where the explicit or implicit contract of employment gives the incumbent a basic remuneration, which is independent of the revenue of the unit for which he/she works.
An 'employer' is a person who, working on his or her own account or with a small number of partners, holds a 'self-employment' job and, in this capacity, on a continuous basis (including the reference week) has engaged one or more persons to work for him/her as 'employees'.
If a person is both employer and employee, he/she shall be allocated to only one group according to the time spent on the job or (if not available) the income received.
An 'own-account worker' is a person who, working on his/her own account or with one or a few partners, holds a 'self-employment job' and has not engaged, on a continuous basis (including the reference week), any 'employees'.
A 'contributing family worker' is a person who
— holds a 'self-employment’ job in a market-oriented establishment operated by a related person, living in the same household, and
— cannot be regarded as a partner (that is an employer or own-account worker) because the degree of commitment to the operation of the establishment, in terms of working time or other factors to be determined by national circumstances, is not at a level comparable to that of the head of the establishment.
A 'member of a producers' cooperative' is a person who holds a 'self-employment' job in an establishment organised as a coop erative, in which each member takes part on an equal footing with other members in determining the organisation of production, sales and/or other work, the investments and the distribution of the proceeds among the members.
3.4.11. Statistical concepts and definitions - Place of work
The location of the place of work is the geographical area in which a currently employed person does his/her job.
The place of work of those mostly working at home is the same as their usual residence. The term 'working' refers to work done as an 'employed person' as defined under the topic 'Current activity status'. 'Mostly' working at home means that the person spends all or most of the time working at home, and less, or no, time in a place of work other than at home.
3.4.12. Statistical concepts and definitions - Educational attainment
'Educational attainment' refers to the highest level successfully completed in the educational system of the country where the education was received. All education which is relevant to the completion of a level is taken into account even if this was provided outside schools and universities.
Persons aged 15 years or over are classified under only one of the categories according to their educational attainment (highest completed level). Persons under the age of 15 years are classified under 'not applicable'.
3.4.13. Statistical concepts and definitions - Size of the locality
A locality is defined as a distinct population cluster, that is an area defined by population living in neighbouring or contiguous buildings. Such buildings may either:
(a) form a continuous built-up area with a clearly recognisable street formation; or
(b) though not part of such a built-up area, comprise a group of buildings to which a locally recognised place name is uniquely attached; or
(c) though not meeting either of the above two criteria, constitute a group of buildings, none of which is separated from its nearest neighbour by more than 200 metres.
3.4.14. Statistical concepts and definitions - Place of birth
Place of birth is defined as the place in which the birth took place.
Information on the country of birth is based on the international boundaries existing on 31 December 2011. 'EU Member State', in particular, means a country that is a member of the European Union on 31 December 2011. The list of countries in the breakdown 'country/place of birth' serves only for statistical purposes.
For Switzerland that is not a EU Member State, the category 'Other EU Member State' shall be read as 'EU Member State'.
The category 'Information not classifiable according to current borders' covers those persons whose country of birth existed at the time of the birth, but no longer exists at the time of the census, and who cannot be allocated uniquely to one country existing at the time of the census, i.e. according to current borders.
For countries that are not described in legislation 1201:
Kosovo (8256) is under EUR_OTH, Sahara W (8372) under AFR_OTH, Sud Soudan (8363) under AFR_OTH, Palestine (8550) under ASI_OTH.
3.4.15. Statistical concepts and definitions - Country of citizenship
Citizenship is defined as the particular legal bond between an individual and his/her State, acquired by birth or naturalisation, whether by declaration, option, marriage or other means according to the national legislation.
A person with two or more citizenships is allocated to only one country of citizenship, to be determined in the following order of precedence:
1. reporting country; or
2. if the person does not have the citizenship of the reporting country: other EU Member State; 3. if the person does not have the citizenship of another EU Member State: other country outside the European Union.
'EU Member State' means a country that is a member of the European Union on 31 December 2011. The list of countries in the breakdown 'Country of citizenship' shall only apply for statistical purposes.
For Switzerland that is not a EU Member State, the category 'citizenship not of reporting country, but other EU Member State' shall be changed to 'citizenship of an EU Member State'.
For countries recognized by Switzerland and not by UE:
Kosovo (8256) is under EUR_OTH, Sahara W (8372) under AFR_OTH, Sud Soudan (8363) under AFR_OTH, Palestine (8550) under ASI_OTH
3.4.16. Statistical concepts and definitions - Year of arrival in the country
The year of arrival is the calendar year in which a person most recently established usual residence in the country. The data for 2011 refer to the time span between 1 January 2011 and 31 December 2011.
3.4.17. Statistical concepts and definitions - Residence one year before
This indicates the relationship between the current place of usual residence and the place of usual residence one year prior to the census. Children under one year of age are classified under 'Not applicable'.
For all persons that have changed their usual residence more than once within the year prior to the reference date, the previous place of usual residence is the last usual residence from which they moved to their current place of usual residence.
3.4.18. Statistical concepts and definitions - Housing arrangements
The topic 'Housing arrangements' covers the whole population and refers to the type of housing in which a person usually resides at the time of the census. This covers all persons who are usual residents in different types of living quarters, or who do not have a usual residence and stay temporarily in some type of living quarters, or who are roofless, sleeping rough or in emergency shelters, when the census is taken.
Occupants are persons with their usual residence in the places listed in the respective category.
'Conventional dwellings' are structurally separate and independent premises at fixed locations which are designed for permanent human habitation and are, at the reference date, either used as a residence, or vacant, or reserved for seasonal or secondary use.
'Separate' means surrounded by walls and covered by a roof or ceiling so that one or more persons can isolate themselves. 'Independent' means having direct access from a street or a staircase, passage, gallery or grounds.
'Other housing units' are huts, cabins, shacks, shanties, caravans, houseboats, barns, mills, caves or any other shelter used for human habitation at the time of the census, irrespective if it was designed for human habitation.
'Collective living quarters' are premises which are designed for habitation by large groups of individuals or several households and which are used as the usual residence of at least one person at the time of the census.
'Occupied conventional dwellings', 'other housing units' and 'collective living quarters' together represent'‘living quarters'. Any 'living quarter' must be the usual residence of at least one person.
The sum of occupied conventional dwellings and other housing units represents 'housing units'.
The homeless (persons who are not usual residents in any living quarter category) can be persons living in the streets without a shelter that would fall within the scope of living quarters (primary homelessness) or persons moving frequently between temporary accommodation (secondary homelessness).
3.4.19. Statistical concepts and definitions - Type of family nucleus
The family nucleus is defined in the narrow sense, that is as two or more persons who belong to the same household and who are related as husband and wife, as partners in a registered partnership, as partners in a consensual union, or as parent and child.

The legal residence is the main residence of the person as registered in the population register, regardless of temporary absences for purposes of recreation, holidays, visits to friends and relatives, business, medical treatment or religious pilgrimage. Persons who are enumerated but do not meet the criteria for permanent legal residence in the place of enumeration, i.e. do not live or do not expect to live in the place of enumeration for a continuous perod of at least 12 months, are considered temporarily present and are therefore not counted in the total permanent resident population.
3.7. Reference area
Data are available at different levels of geographical detail: national, NUTS2, NUTS3 and local administrative units (LAU2)

15.1. Comparability - geographical
Data from registers (STATPOP): Persons are enumerated where they are legally registered in the population registers, regardless of where most of the daily period of rest is spent. This also applies for children who alternate between two places of residence. Persons who work or study abroad but return home on a regular basis are included in the census population if they are registered in the population registers. The place of enumeration for homeless or roofless persons, nomads, vagrants and persons is also the commune where they are legally registered; if they are not officially registered in the commune, the FSO gets no information and therefore does not enumerate them.
Data from the sample survey (Structural Survey): Only the population aged 15 and over, and living in private households, is enumerated. Foreign diplomatic personnel and their families are excluded.
Au niveau des logements, que ce soient des données de registre (StatBL) ou relevées par échantillon (SE), ne sont recensés que ceux qui comportent un équipement de cuisine (cuisine ou cuisinette). Tous sont considérés ici comme 'Conventional dwellings', qu'ils soient either used as a residence, or vacant, or reserved for seasonal or secondary use, ou utilisés à d'autres fins que l'habitation, ou inhabitables. Tous les bâtiments et les logements recensés sont terminés au jour de référence.
15.2. Comparability - over time
15.3. Coherence - cross domain
Figures provided by the National Statistical Institutes in the framework of the 2011 Population and Housing Census may differ from those transmitted in other statistical domains due to the cross domain differences in definitions and methodologies used. For additional information please see metadata specific to each domain.
15.4. Coherence - internal
Internal coherence is assured by regulations defining breakdowns and definitions of topics (Regulation (EC) No 1201/2009, Regulation (EU) No 519/2010, Regulation (EU) No 1151/2010)
The new annual Swiss Census has considerably reduced the burden on communes and respondents. Indeed register harmonization at national, regional and local levels have made it possible that data from registers can be extracted four times a year. The overall costs of compiling data thus have been reduced.
Further measures that helped reduce cost were: application of project management procedures, controlling, good coordination between developers of IT-applications and census specialists, extensive testing of Census procedures and IT-applications, quality control.
17.1. Data revision - policy

Since 2010, data on population and housing censuses are collected every year, with reference date 31 December.
18.3. Data collection
Register-based data:
a) A special law was passed to define the content (only census data) of the already existing registers of persons used for the census: the Federal Act of 23 June 2006 on the Harmonisation of the Register of Residents and of other Official Registers of Persons (Register Harmonisation Act, RHA; SR 431.02. See also the Ordinance on Register Harmonisation of 21 November 2007, SR 431.021). It also addresses the transmission of data to the FSO, the legal obligations regarding registration, the delays in reporting, etc.
Art. 11 Duty to notify specifies:
The cantons shall issue the required regulations so that:
a. natural persons notify the official agency responsible for maintaining the register of residents within 14 days of relocation;
b. the persons required to report provide truthful information on the data defined in Article 6 and, if required, the relevant documents.
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).
b) Concerning data on buildings and dwellings, the rules concerning the maintenance of the register are fixed in the Ordinance of 31 May 2000 on the Federal Register of Buildings and Dwellings (SR 431.841).
Questionnaire-based data:
The questionnaire is available here (see "Translation aid for the structural survey 2013"):
http://www.bfs.admin.ch/bfs/portal/en/index/news/02/03/02.html
The sample population (sample of persons aged 15 and over living in private households) is drawn from the register-based data. Persons receive the questionnaires per post and can return it the same way or answer via the internet.
18.4. Data validation
All data treatments are done in accordance with the EDIMBUS Recommended Practices on Editing and Imputation in Cross Sectional Business Surveys (see link below). Although these recommendations have been developped for business surveys, they are also applicable to census surveys.

18.6. Adjustment
Since 2010, a new Census is conducted and evaluated on an annual basis by the Swiss Federal Statistical Office (FSO). The census consists of four separately conducted surveys, two of which have been used in the preparation of the data for the Census Hub Hypercubes – the Register Survey and the Structural Survey.
In the Register Survey, data from the local, cantonal and national population registers as well as from the national Buildings and Dwellings Register is used. It provides information on: a) persons and households such as age, sex, marital status, nationality, household size, etc.; b) buildings and dwellings such as period of construction, building category, number of dwellings, number of rooms, useful floor space etc. The Register Survey provides basic information about the entire population, buildings and dwellings; the data can be evaluated at a very detailed geographical level since for every building, metric geo-coordinates are available and a building and dwelling identifier is associated to every person in the population registers.
The Structural Survey provides information on the themes of population, households, families, housing, employment, mobility, education, language, religion and migration. The sampled population is composed of persons aged 15 or more of the permanent resident population living in private households; each year a minimum of 200'000 persons is randomly selected in order to participate in the Structural Survey. Cantons or large cities can enlarge the sample for their territory on request. Overall approximately 4% of the resident permanent population aged 15 years or older is surveyed in writing (participation by internet or by completing a paper questionnaire). The survey complements the information collected from the registers and provides additional statistics on the structure of the population. Survey results with a sufficiently high quality are available at the following geographic levels: Switzerland (NUTS 1), major regions (NUTS 2), cantons (NUTS 3) and communes (LAU 2) with more than 15’000 inhabitants.
In contrast to the Register Survey which contains information on the entire resident population, the Structural Survey is based only on the resident permanent population aged 15 years or older.
The fact that the Register Survey and the Structural Survey use different universes and are distinct by theme, leads to the situation where population totals of evaluated data vary.
If a hypercube used in the Census Hub is based on Structural Survey data then the result will be 6’587’556 persons, which corresponds to the total population aged 15 years or older and living in private households. If a hypercube is based on Register Survey data then the resulting total resident population will be 7’954’662 persons.
18 May 2015
The EU programme for the 2011 population and housing censuses include data on persons, private households, family nuclei, conventional dwellings and living quarters.
Persons enumerated in the 2011 census are those who were legally resident in the territory of the reporting country at the census reference date. The legal residence is the main residence of the person as registered in the population register, regardless of temporary absences for purposes of recreation, holidays, visits to friends and relatives, business, medical treatment or religious pilgrimage. Persons who are enumerated but do not meet the criteria for permanent legal residence in the place of enumeration, i.e. do not live or do not expect to live in the place of enumeration for a continuous perod of at least 12 months, are considered temporarily present and are therefore not counted in the total permanent resident population.
Data are available at different levels of geographical detail: national, NUTS2, NUTS3 and local administrative units (LAU2)
