3.1. Data description | |||
All data used in the Norwegian census 2011 were retrieved from statistical registers. These are mostly based on administrative registers. Most of the statistical registers used were established before the census. However, a combined register of households and dwellings was established as a part of census preparations. The census in 2011 was the first totally register-based census in Norway. Annexes: Census without questionnaire Towards register-based census step by step |

3.4. Statistical concepts and definitions | |||
3.4.1. Statistical concepts and definitions - Usual residence Usual residence means the place where a person normally spends the daily period of rest, regardless of temporary absences for purposes of recreation, holidays, visits to friends and relatives, business, medical treatment or religious pilgrimage. Classification as male or female as in the Central Population Register. 3.4.3. Statistical concepts and definitions - AgeThe age reached at the reference date (in completed years). 3.4.4. Statistical concepts and definitions - Marital statusMarital 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. 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. Private households may be defined according to the 'housekeeping concept' or, if this is not possible, Member States may apply the 'household-dwelling' concept. . 'Current activity status' is the current relationship of a person to economic activity. The reference period is the last seven days prior to enumeration. 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. 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. 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. The location of the place of work is the geographical area in which a currently employed person does his/her job. '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. 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: Place of birth is defined as the place of usual residence of the mother at the time of the birth, or, if not available, as the place in which the birth took place. 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. 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 the reference date. 3.4.17. Statistical concepts and definitions - Residence one year beforeThis 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'. 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. 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. Size of family nucleus is the number of persons living in the 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. 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. Private households may be defined according to the 'housekeeping concept' or, if this is not possible, Member States may apply the 'household-dwelling' concept. Size of private household is the number of persons living in the household. Private households may be defined according to the 'housekeeping concept' or, if this is not possible, Member States may apply the 'household-dwelling' concept. The topic 'Tenure status of households' refers to the arrangements under which a private household occupies all or part of a housing unit. '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. 'Occupied conventional dwellings' are conventional dwellings which are the usual residence of one or more persons at the time of the census. 'Unoccupied conventional dwellings' are conventional dwellings which are not the usual residence of any person at the time of the census. The topic 'Type of ownership' refers to the ownership of the dwelling and not to that of the land on which the dwelling stands. The number of occupants of a housing unit is the number of people for whom the housing unit is the usual residence. 3.4.28. Statistical concepts and definitions - Useful floor spaceUseful floor space is defined as the floor space measured inside the outer walls excluding non-habitable cellars and attics and, in multi-dwelling buildings, all common spaces; or the total floor space of rooms falling under the concept of 'room'. A 'room' is defined as a space in a housing unit enclosed by walls reaching from the floor to the ceiling or roof, of a size large enough to hold a bed for an adult (4 square metres at least) and at least 2 metres high over the major area of the ceiling. Number of rooms is not reported for Norway. 3.4.30. Statistical concepts and definitions - Density standard (floor space)The topic ‘Density standard’ relates the useful floor space in square metres or the number of rooms to the number of occupants, as specified under the topic 'Number of occupants'. Since data on useful floor space are not available in registers, 'Utility floor space' is reported as a substitute. The topic ‘Density standard’ relates the useful floor space in square metres or the number of rooms to the number of occupants, as specified under the topic 'Number of occupants'. The topic ‘Water supply system‘ relates to the existence of piped water in the housing unit. 3.4.33. Statistical concepts and definitions - Toilet facilitiesThe topic ‘toilet facilities relates to the existence of flush toilet(s) in the housing unit. 3.4.34. Statistical concepts and definitions - Bathing facilitiesA bathing facility is any facility designed to wash the whole body and includes shower facilities. 3.4.35. Statistical concepts and definitions - Type of heatingA housing unit is considered as centrally heated if heating is provided either from a community heating centre or from an installation built in the building or in the housing unit, established for heating purposes, without regard to the source of energy. Housing units with permanent electric heaters are regarded as having central heating. 3.4.36. Statistical concepts and definitions - Type of buildingThe topic 'Dwellings by type of building' refers to the number of dwellings in the building in which the dwelling is placed. 3.4.37. Statistical concepts and definitions - Period of constructionThe topic 'Dwellings by period of construction' refers to the year when the building in which the dwelling is placed was completed. |

3.5. Statistical unit | |||
The EU programme for the 2011 population and housing censuses include data on persons, private households, family nuclei, conventional dwellings and living quarters |
|||
3.6. Statistical population | |||
Persons enumerated in the 2011 census are those who were usually resident in the territory of the reporting country at the census reference date. Usual residence means the place where a person normally spends the daily period of rest, regardless of temporary absences for purposes of recreation, holidays, visits to friends and relatives, business, medical treatment or religious pilgrimage. In Norway registered residence is reported as a substitute for usual residence, see definition of the topic 'Usual residence' (3.4.1). |

According to The Norwegian Statistics Act, Article 2.6, information collected in accordance with any prescribed obligation to provide information, or which is given voluntarily, shall under no circumstances be published in such a way that it can be traced back to the supplier of any data or to any other identifiable individual to the detriment of the person concerned. Annexes: Confidentiality protection of large frequency data cubes |
|||
7.2. Confidentiality - data treatment | |||
Small count rounding has been applied in order to protect the Norwegian Census hypercubes against reasonable means of attack. Counts of 1 and 2 were rounded unbiasedly to 0 or 3. Marginal counts were recalculated and the maximum deviation from original counts at one and two variable level was calculated. 10 000 solutions were generated and the solution with the smallest maximum deviation was selected. I order to ensure as much consistency as possible groups of hypercubes were combined to aggregated cubes and rounded jointly. Only 1s and 2s in the aggregated cubes that contributed to 1s and 2s in the corresponding hypercubes were selected for rounding. In order to secure the credibility of the method and the quality of the rounded results, the rounding of some aggregated cubes were based on the 1s and 2s in the Primary Marginal Distributions. For hypercubes in these aggregated cubes, all secondary cells were labeled Confidential. Applying this method the census hypercubes have to our best ability been protected against all disclosure attacks that Statistics Norway considers likely to occur.

In a register-based census data are retrieved from several statistical registers that are operated continuously. Quality assurance is basically managed for each statistical register system and is not specific for the census. However, some additional measures have been taken to ensure maximum compliance with the EU regulation. |
|||
12.2. Quality management - assessment | |||
12.2.1. Coverage assessment | |||
Coverage related to registered population: In the Norwegian census registered resident population is reported as a substitute for usual resident population. Given this definition, the target population could be defined as those persons who according to the regulations for population registration should be registered as resident at census time. Under-coverage is very difficult to assess in a register-based statistical system due to lack of independent data (all statistical surveys are using the registered population as frame). Registrations of births and deaths are complete and very rarely delayed. Notifications of immigration are also rarely delayed since persons legally living in Norway will indeed have self-interest to register as residents. Consequently, under-coverage will be very low.

14.1. Accuracy - overall | |||
14.1.1. Accuracy overall - Usual residence There are no particular reasons for data unreliability for this topic. However, it should be noticed that registered residence is reported as a substitute for usual residence. 14.1.2. Accuracy overall - SexThere are no particular reasons for data unreliability for this topic. 14.1.3. Accuracy overall - AgeThere are no particular reasons for data unreliability for this topic. 14.1.4. Accuracy overall - Marital statusThere are no particular reasons for data unreliability for this topic. However it should be noticed that persons in 'registered partnership' are classified under 'married'. 14.1.5. Accuracy overall - Family statusPartners in same-sex consensual unions are not identified as relevant data are not available from registers. It should be noticed that persons in 'registered partnership' are classified under 'married'. 14.1.6. Accuracy overall - Household statusPartners in same-sex consensual unions are not identified as relevant data are not available from registers. For confidentiality reasons persons in 'registered partnership' are classified under 'married'. 14.1.7. Accuracy overall - Current activity statusFor a small group of employees and self-employed/employers, classification by employment is based mainly on information from tax registers. For these groups there is some uncertainty attached to the whether the persons actually were employed in census week or not. The data source for unemployment is a register on unemployed kept by the national labour and welfare administration. This register only comprises those persons seeking work through an employment office. Hence only unemployed seeking work this way are classified as ‘unemployed' in the census. 14.1.8. Accuracy overall - OccupationFor 15 per cent of the current economically active persons 'Occupation' is imputed. This may affect the overall accuracy for this topic. 14.1.9. Accuracy overall - IndustryThere are no particular reasons for data unreliability for this topic. 14.1.10. Accuracy overall - Status in employment'Contributing family workers' cannot be identified as a separate category. 14.1.11. Accuracy overall - Place of workThe number of persons with place of work 'not in the territory of the member state' is under-estimated as it comprises only employees in the Norwegian embassies. 14.1.12. Accuracy overall - Educational attainmentThere are no particular reasons for data unreliability for this topic. 14.1.13. Accuracy overall - Size of the localityThere are no particular reasons for data unreliability for this topic. 14.1.14. Accuracy overall - Place of birthThere are no particular reasons for data unreliability for this topic 14.1.15. Accuracy overall - Country of citizenshipThere are no particular reasons for data unreliability for this topic 14.1.16. Accuracy overall - Year of arrival in the countryThere are no particular reasons for data unreliability for this topic. 14.1.17. Accuracy overall - Residence one year beforeThere are no particular reasons for data unreliability for this topic. 14.1.18. Accuracy overall - Housing arrangementsRegistered place of residence is reported as a substitute for usual place of residence. In the registers available no persons are classified as living in 'other housing units' or as 'homeless'. More information, see Comparability - geographical (item 16.1). 14.1.19. Accuracy overall - Type of family nucleusPartners in same-sex consensual unions are not identified as relevant data are not available from registers. Furthermore, it should be noticed that persons in 'registered partnership' are classified under 'married'. 14.1.20. Accuracy overall - Size of family nucleusThere are no particular reasons for data unreliability for this topic. 14.1.21. Accuracy overall - Type of private householdApplying the household dwelling concept, the number of occupied housing units and private households should be equal, and the locations of the housing units and households should be identical. Due to quality problems in the registers the number of private households and occupied housing units is not fully equivalent. In the census statistics there are 19 000 more private households than occupied dwellings. There are no particular reasons for data unreliability for this topic. 14.1.23. Accuracy overall - Tenure status of householdThere are no particular reasons for data unreliability for this topic. However, it should be noticed that for 15 per cent of all households 'tenure status' have been imputed. 14.1.24. Accuracy overall - Type of living quarterThe number of 'collective living quarters' is estimated from the number of 'persons in an institutional household'. For some persons living in institutions the information on precise address is less reliable than for persons living in conventional dwellings, affecting the reliability of the estimates of the number of collective living quarters. 14.1.25. Accuracy overall - Occupancy statusData on households and dwellings are produced by combining information from the dwelling register (Cadaster) and the population register. Due to some quality problems in both registers, the estimate for unoccupied dwellings is considered as less reliable than the estimate for occupied dwellings. 14.1.26. Accuracy overall - Type of ownershipThere are no particular reasons for data unreliability for this topic. However, it should be noticed that for 14 per cent of all occupied conventional dwellings 'type of ownership' has been imputed. 14.1.27. Accuracy overall - Number of occupantsThere are no particular reasons for data unreliability for this topic. 14.1.28. Accuracy overall - Useful floor spaceThere are no particular reasons for data unreliability for this topic. 14.1.29. Accuracy overall - Number of roomsStatistics on this topic is not reported. Instead the preferred topic 'useful floor space' is reported. 14.1.30. Accuracy overall - Density standard (floor space)There are no particular reasons for data unreliability for this topic 14.1.31. Accuracy overall - Density standard (number of rooms)Statistics on this topic is not reported. Instead the preferred topic 'density standard (floor space)' is reported. 14.1.32. Accuracy overall - Water supply systemIn the dwelling register information on this topic is missing for approximately 60 per cent of all dwellings. However, almost all of these dwellings have either bathrooms, toilets or a sewerage system, meaning that they most certainly should be classified as having ‘piped water‘. Using this method, more than 99.9 per cent of all dwellings would be classified as having ‘piped water‘. For the remaining dwellings it is difficult to determine whether they should be classified as having ‘no piped water‘ or as ‘not stated‘. Based on this fact, and also on results from other surveys, it is estimated that all conventional dwellings have piped water. 14.1.33. Accuracy overall - Toilet facilitiesAccording to the dwelling register 96 per cent of all conventional, occupied dwellings have a flush toilet. For the remaining dwellings it is not possible to determine whether they do have a flush toilet or if they should be classified as ‘not stated‘. In the 2001 census 97 per cent of the dwellings had both toilet facilities and bathing facilities. This indicates that the percentage with flush toilets in the 2011 census should be somewhat higher than 96 per cent. 14.1.34. Accuracy overall - Bathing facilitiesAccording to the dwelling register 96 per cent of all conventional, occupied dwellings have fixed bath or shower. For the remaining dwellings it is not possible to determine whether they do not have bathing facilities or if they should be classified as ‘not stated‘. In the 2001 census 97 per cent of the dwellings had both toilet facilities and bathing facilities. This indicates that the percentage with bathing facilities in the 2011 census should be somewhat higher than 96 per cent. 14.1.35. Overall accuracy - Type of heatingIn the dwelling register information on this topic is missing for approximately 70 per cent of all occupied conventional dwellings. Even if additional data sources are used, information is missing for more than 20 per cent of the dwellings. Dwellings with permanent electric heaters are regarded as having central heating. According to the sample survey Energy consumption in households, 95 per cent of all dwellings have electric heaters and 6 per cent have other types of central heating. Even if some dwellings have both these types heating, it can be concluded that almost all dwellings have central heating according to the definition applied. Based on this fact it is estimated that all conventional dwellings have central heating. 14.1.36. Overall accuracy - Type of buildingThere are no particular reasons for data unreliability for this topic. 14.1.37. Overall accuracy - Period of constructionThere are no particular reasons for data unreliability for this topic |

16.1. Comparability - geographical | |||
Usual place of residence: Registered residence is reported as a substitute. To be registered as resident in Norway, a person should have lived, or have the intention to live, in the country for at least six months, as compared to twelve months in the definition of usual residence. There are a few exceptions. Asylum seekers are not registered as residents before they have granted a residence permit even if they have stayed in the country for more than six months. Unmarried third level students may choose whether they want to be registered at their parents’ address or at the address at their place of study. This means that some third level students with place of study abroad is included in the census population even if they have stayed abroad for more than six mints. This applies to students with their place of study in Norway as well as abroad. More information about coverage, see Coverage assessment (item 12.2.1). |

20.2. Frequency of data collection | |||
Data on population and housing censuses are collected every decade, in a reference year that falls during the beginning of every decade |
|||
20.3. Data collection | |||
All census data are collected from registers. Most registers used are administrative registers kept by governmental or local authorities; the main exception being the statistical register on education kept in Statistics Norway. Data from administrative registers are combined in several statistical register that are kept in Statistics Norway on a permanent basis. These registers are used in production of subject matter statistics and updated at least annually. The same registers are used as data sources for the census and hence, the census has no separate data collection. |
|||
20.4. Data validation | |||
Census data are collected from several statistical register kept in Statistics Norway. These are permanent registers, and data validation is integrated in the maintenance of these register. The procedures used for validation may vary between the register systems, but some basic principles are applied. All data retrieved from administrative registers are checked for completeness and internal consistency. When data from several sources are combined, procedures have been established to ensure consistent statistical data. In some register systems it has been necessary to establish comprehensive procedures to achieve this goal. For example, in the statistical labour market register, the system comprises modules for consistency management between various data sources (jobs, self-employment and unemployment), selection of main job and classification by employment in the reference week. |
|||
20.5. Data compilation | |||
A census micro file is established by combining data from different statistical registers. Data capturing and coding is managed by each statistical register system. All data are captured electronically. Coding is mainly done in the administrative registers, that is, by the authorities responsible for the registers. |
