3.1. Data description
The data present the results of the 2021 EU census on population and housing, following Regulation (EC) 763/2008; Regulation (EU) 2017/543; Regulation (EU) 2017/712 and Regulation (EU) 2017/881.
3.1.1. Impact of the COVID-19 pandemic on census methodology
Covid-19 has had no impact on the census methodology.
3.2. Classification system
The following classification has been used:
- Nomenclature of Territorial Units for Statistics (NUTS 2021)
- International Standard Classification of Education (ISCED-2011)
- International standard classification of occupations (ISCO-08)
- Statistical Classification of Economic Activities in the European Community (NACE Rev 2)
3.3. Coverage - sector
Not applicable.
3.4. Statistical concepts and definitions
The information is given separately for each census topic.
3.4.1. Statistical concepts and definitions - Usual residence
‘Usual residence’ is defined as the place of registered residence.
3.4.2. Statistical concepts and definitions - Sex
‘Sex’ refers to the registered sex.
3.4.3. Statistical concepts and definitions - Age
The age reached in completed years at the reference date.
3.4.4. Statistical concepts and definitions - Marital status
Marital status is defined as the (legal) conjugal status of an individual in relation to the marriage laws in Denmark.
A person is classified according to his/her most recently acquired legal marital status at the reference date.
3.4.5. Statistical concepts and definitions - Family status
The family nucleus is defined in a 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.
3.4.6. Statistical concepts and definitions - Household status
Private households are identified using the ‘household-dwelling concept’.
The household-dwelling concept considers all persons living in a housing unit to be members of the same household, such that there is one household per occupied housing unit.
In some cases young children might be registered as living alone. This can be the case if the migration/relocation of the parent is not registered at the same time as the migration of the child.
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.
3.4.8. Statistical concepts and definitions - Occupation
Occupation refers to the type of work done in a job. ‘Type of work’ is described by the main tasks and duties of the work.
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) refers to the kind of production or activity of the establishment or similar unit in which the job of an employed 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
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’.
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.
Information on persons who do not have a fixed place of work but who report to a fixed address at the beginning of their work period (for example bus drivers, airline crew, operators of street market stalls that are not removed at the end of the workday) refer to that address. This group may also include individuals who travel to work, on a regular basis, across the border to a neighbouring country. Breakdown ‘No fixed place of work (inside or outside the Member State)’ includes all persons without fixed place of work but will also refer to persons such as sailors, fishermen and offshore workers for whom it may not be possible to allocate the place of work.
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.
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 neighboring or contiguous buildings.
Such buildings may be either:
(a) form a continuous built-up area with a clearly recognizable street formation; or
(b) though not part of such a built-up area, comprise a group of buildings to which a locally recognized 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 neighbor by more than 200 meters.
3.4.14. Statistical concepts and definitions - Place of birth
Information on the ‘Place of birth’ is collected according to the place of usual residence of the mother at the time of the birth, or, if not available, the place in which the birth took place, on the basis of international boundaries existing on 1 January 2021.
For reporting countries that are EU Member States, the sub-category under the category 'other EU Member State' that refers to their Member State does not apply. For reporting countries that are not EU Member States, 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.
The category 'outside any country' covers persons for whom the usual residence of the mother at the time of the birth is not known and who where born outside the borders of any country, for example at sea or in the air.
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 naturalization, 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:
- reporting country
- if the person does not have the citizenship of the reporting country: other EU Member State
- 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 1 January 2021. The list of countries in the breakdown 'Country of citizenship' shall only apply for statistical purposes.
For reporting countries that are EU Member States, the sub-category of the category 'citizenship not of reporting country, but other EU Member State' that refers to their Member State does not apply. For reporting countries that are not EU Member States, the category 'citizenship not of reporting country, but other EU Member State' shall be changed to 'citizenship of an EU Member State'.
Persons who are neither citizens of any country nor stateless and who have some but not all of the rights and duties associated with citizenship shall be classified under 'recognised non-citizens'.
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 2021 refer to the time span between 1 January 2021 and the reference date.
3.4.17. Statistical concepts and definitions - Residence one year before
The relationship between the current place of usual residence and the place of usual residence one year prior to the census.
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.
'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 a 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. A child who alternates between two households (for instance if his or her parents are divorced) shall consider the one where he or she spends the majority of the time as his or her household. Where an equal amount of time is spent with both parents the household shall be the one where the child is found at the time on census night.
The term couple shall include married couples, couples in registered partnerships, and couples who live in a consensual union.
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.
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 not included in the definition of a family.
3.4.20. Statistical concepts and definitions - Size of family nucleus
The family nucleus is defined in a 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.
3.4.21. Statistical concepts and definitions - Type of private household
Private households are identified using the ‘household-dwelling concept’.
The household-dwelling concept considers all persons living in a housing unit to be members of the same household, such that there is one household per occupied housing unit.
There are a few cases where child is registered as living alone. This is because of technical issues with the regsitration of migrations at census night.
3.4.22. Statistical concepts and definitions - Size of private household
Private households are identified using the ‘household-dwelling concept’.
The household-dwelling concept considers all persons living in a housing unit to be members of the same household, such that there is one household per occupied housing unit.
'Primary homeless persons' are persons living in the streets without a shelter that would fall within the scope of living quarters.
3.4.23. Statistical concepts and definitions - Tenure status of households
The topic ‘Tenure status of households’ refers to the arrangements under which a private household occupies all or part of a housing unit.
3.4.24. Statistical concepts and definitions - Type of living quarter
A living quarter is housing which is the usual residence of one or more persons.
'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.
3.4.25. Statistical concepts and definitions - Occupancy status
‘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.
3.4.26. Statistical concepts and definitions - Type of ownership
‘Type of ownership’ refers to the ownership of the dwelling and not to that of the land on which the dwelling stands. It shows the tenure arrangements under which the dwelling is occupied.
'Owner-occupied dwellings' are those where at least one occupant of the dwelling owns parts or the whole of the dwelling. 'Cooperative ownership' refers to ownership within the framework of a housing cooperative.
'Rented dwellings' are those where at least one occupant pays a rent for the occupation of the dwelling, and where no occupant owns parts or the whole of the dwelling.

Statistics Denmark collects data from administrative registers from public authorities. The data is used to create statistical registers on individual level. The main administrative registers used for the statistical registers which are used in the Census are the Central Register on Persons, the Building and Dwelling Register, the Business Register and the Tax Register. The administrative registers are all of high quality as they are necessary tools for the Danish authorities. The statistical registers are constantly being maintained and if new technological possibilities appear the registers are improved accordingly. The registers can be linked via the unique person_id, the work-place id and the address.
There has been no new registers from 2011 onwards.
