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.
Persons usually resident in the place of enumeration but absent, or expected to be absent, at the time of the census for less than one year shall be considered as temporarily absent persons and thus included in the total unsually population. In contrast, persons living or expected to live outside the place of enumeration for one year or more shall not be considered temporarily absent and shall therefore be 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 usual 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 usually resident population.

Gender divides people into men and women.

The age reached at the reference date (in completed years).

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'.

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. 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.

Private households may be defined according to the 'housekeeping concept' , or, if this is not possible, Member States may apply the 'household-dwelling' concept.
1. Housekeeping concept
According to the housekeeping concept, a private household is either:
(a) A one-person household, that is a person who lives alone in a separate housing unit or who occupies, as a lodger, a separate room (or rooms) of a housing unit but does not join with any of the other occupants of the housing unit to form part of a multiperson household as defined below; or
(b) A multiperson household, that is a group of two or more persons who combine to occupy the whole or part of a housing unit and to provide themselves with food and possibly other essentials for living. Members of the group may pool their incomes to a greater or lesser extent.
2. 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 the household dwelling concept, then, the number of occupied housing units and the number of households occupying them is equal, and the locations of the housing units and house­ holds 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' 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'.

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'.

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.

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.

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.

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.

'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'.

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.

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.
Information on the country of birth is based on the international boundaries existing on 1 January 2011. 'EU Member State', in particular, means a country that is a member of the European Union on 1 January 2011. The list of countries in the breakdown 'country/place of birth' serves only for statistical purposes.
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.

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 1 January 2011. 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'.

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.

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.

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).

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.

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.

Common reminder of EU legislation

The 2011 Population and housing census (the “Census”) was managed in the Czech Republic under Act No 296/2009 on the 2011 Population and Housing Census, and Regulation (EC) No 763/2008 of the European Parliament and of the Council on population and housing censuses.

Act No 296/2009 governs the preparation and enactment of the 2011 Population and housing in the Czech Republic and the conditions for providing data from this census. It further makes reference to Act No 326/1999, on the residence of foreigners in the Czech Republic, Act No 325/1999, on asylum, Act No 221/2003, on temporary protection for foreigners, Act No 137/2006,  on public contracts, Act No 365/2000, on public administration information systems, Constitutional Act No 347/1997, on the creation of territorial self-governing units and a change to the Czech National Council Constitutional Act No 1/1993., Act No 36/1960 Sb., on the territorial division of the state, Act No 128/2000 Sb., on municipalities, Act No 89/1995 Sb., on the state statistics service, Act No 133/2000 Sb., Registration of Inhabitants and Personal Identification Numbers, Act No 359/1992 Sb., on Surveying, Mapping and Cadastral Bodies, Act No 131/2000 Sb., on the Capital City of Prague, Act No 222/1999 Sb., on securing defence of the Czech Republic , Act No 250/2000 Sb., on budget rules for territorial budgets, Act No 269/1994 Sb., on the Criminal Register, Act No 499/2004 Sb., on Archiving and the File Registry, Act No 101/2000 Sb., on the Protection of Personal Data.

Act No 101/2000 on the protection of personal data also covers the processing of confidential statistical data on physical persons (individuals) for statistical purposes.

The securing of statistical confidentiality, managing the risk of disclosure of statistical data.

When presenting statistical data, a public database will not allow data designated as confidential to be shown (i.e. given the attribute of primary confidentiality) – in tables such data will be replaced with a standard data (i.d. or c.d. in any English language version). Also in tables giving confidential data the question of secondary protection of confidentiality is resolved – a table is not offered to users on-line, but sent later after secondary confidentiality risks are resolved (using the method of hiding further statistical data under the secondary confidentiality protection methodology). Hiding of additional data allowing the disclosure of primary protected data is arranged by the public database administrators in collaboration with methodologists from the relevant section.

Data are made available 27 months after the end of the reference period (March 2014)

Detailed Report on Quality in Annex

Management and evaluation of the quality of the processes leading to data collection and the data themselves were an integral part of the 2011 Census. It was focused on two areas: factual and statistical quality. Management of factual quality took place through the establishment, monitoring and evaluation of processes (activities), auditing and evaluation of possible risks and systematic proposing of possible remedial measures. Statistical quality was assessed using a number of instruments: quality indicators proposed by the CZSO, quality indicators proposed by Eurostat.

In collaboration with external specialists, the Czech Statistical Office developed a set of “quality indicators” which document and assess all activities related to data collection and processing. The indicators make use of information on the entire life cycle of census forms and later data records stored in CZSO reports and applications, and evaluates them using mathematical and statistical procedures. In this way information was acquired for example on the quality of distribution and collection of census forms, the quality of data processing, and the quality of the data themselves.

Evaluation of quality took the form of Quality Hypercubes[TK1]  QHC) with data defined by Commission (EU) Regulation No 1151/2010, in Annexes II and III. In view of the differing processing of data in each EU member state, in Chapter 12.2 (Quality Management) hereinafter a detailed methodology is given for the evaluation of quality, or more precisely, data and metadata transferred:

Accuracy:

Data sources: The primary data sources (data acquired from census questionnaires and data from administrative sources) were linked to the census microdata database (DS_PERSONS[2]), which is reported on in QHC02. The required data were evaluated as follows:

The number of inhabitants from the census (NBR_POP_CENSUS[3], NBR_ETP_POP_CENSUS): number of all statistical units (persons) stored in the census microdata database.

Estimated target population (NBR_POP_ETP): calculate according to equation [4]Census population + under-coverage + over-coverage. For further clarification of the estimate use was made of available data on the numbers of persons born and deceased in the inter-census period and on numbers of migrants.

Undercoverage (NBR_UNDERCOV, PC_CP_UNDERCOV): undercoverage was calculated using the equation for the target population – census population + overcoverage.

Overcoverage (NBR_OVERCOV, PC_CP_OVERCOV): the calculation is based on the total number of inhabitants enumerated using forms, with their usual residence derived, but who could not be found in the Central Population Register (ISEO).

Number of all record imputations (NBR_IMPU_REC, PC_CP_IMPU_REC): No records were imputed to the census microdata database, therefore the value is always zero. No imputations took place in the primary data sources [5], the number of inhabitants from the census was not increased.

Number of record deletions (NBR_DEL_REC, PC_CP_DEL_REC): the DS_PERSONS source had records deleted for persons to whom a census form could not be delivered and for whom no change was recorded in administrative sources over the previous 5 year (see Chap. 3.3.1). Records were also deleted for persons for whom a usual residence was not given.

The number of non-imputed records in the data source for statistical units belonging to the target population: (NBR_REC_TGT_NIMPU, PC_CP_REC_TGT_NIMPU, PC_ETP_REC_TGT_NIMPU, PC_NIR_REC_TGT_NIMPU): In the 2011 Census there are no imputed records, therefore all records contained in the census microdata database are non-imputed.

Null data for a unit - before imputation of a record (NBR_UNIT_NINFO, PC_CP_UNIT_NINFO) – for data based on questionnaires: In the 2011 Census no records were imputed, therefor the datum was not evaluated and is always zero.

Topics: The two aforementioned primary data sources (data acquired from census forms and data from administrative sources) were linked in the manner described in Chap 3.3.1 to the census microdata database (DS_PERSONS), which is reported on in QHC03-35. The required data were secured as follows:

Census population (NBR_POP_CENSUS[6]): total of all statistical units (persons) stored in the census microdata database.

Number of records containing formation on a topic (NBR_REC_TOPIC, PC_CP_REC_TOPIC): the number of records for which the topic given contained an answer other than “not identified”.

The number of imputed records containing information on a topic (NBR_IMPU_REC, PC_CP_IMPU_REC): The 2011 Census has no imputed records, therefore the value is always zero.

Imputation of an item for a given topic (NBR_IMPU_ITEM, PC_CP_IMPU_ITEM): For each topic a comparison was made of completeness, specifically of incompleteness of an item at the start of processing and at the end.   If an item for the given topic was not completed at the start and at the end of processing there existed an answer (without “not identified”) the item was evaluated as imputed.

Zero information on an item before imputation (NBR_NINFO_ITEM, PC_CP_NINFO_ITEM): For each topic a comparison of completeness, specifically of incompleteness of the item at the start of processing and at the end.   If a topic at the start of processing was not completed (and should have been) and there was an answer at the end (including “not identified”), the item was evaluated as zero before imputation.

Number of non-imputed observations for a given topic (NBR_NIMPU, PC_CP_NIMPU): For each topic a comparison took place of completeness at the start of processing and at the end.   If a topic was complete at the start of processing (contained any non-zero value) and is also complete at the end of processing (contains any determined non-zero value), then the observation was non-imputed.

Transferred data for hypercubes for a given topic: number of transferred data (automatic count).

The number of non-imputed records containing non-imputed information on a topic divided according to the hypercube for the given topic: In the 2011 Census there are no imputed records, therefore not all records are non-imputed.

The topics [7] for which data on quality are transferred are: place of work (LPW), sex (SEX), age (AGE), marital status (LMS), current activity status (CAS), occupation (OCC), industry (branch of economic activity(IND), status in employment (SIE), educational attainment (EDU), place of birth (POB), country of citizenship (COC), year of arrival in the country YAE), residence one year before the census (ROY), type of housing (HAR), usual residence (GEO), size of locality of residence (LOC), household status (HST),  family status (FST).

For the last four named topics data on quality cannot be evaluated because of the differing methods for calculation – the individual indicators were derived by special algorithms, to which quality evaluation by comparison of processing versions could not be applied.

Completeness: Data are collected across the whole the Czech Republic for all statistical units at all prescribed geographical levels. Data transferred to the EU in the form of QHC01 do not contain the special cell values “not available” (CMPL_N), not available, flagged as “unreliable” (CMPL_NU), “not available” flagged confidential (CMPL_NC), nor number of numerical cell values flagged as “unreliable” (CMPL_U). The Czech Republic transfers values in that territorial breakdown which does not require data protection in the sense of their being replaced with special values (concerns the values “not available” and “not available” flagged as “confidential”). Neither are there any data which meet the definition of the special value “not available” flagged as “unreliable”.

The 2011 Census did not contain any post-enumeration survey. Following expiration of the deadlines for submission of census forms supplemental inquiries took place from 20^th to 25^th May. This supplemental inquiry was not covered by the Act on the Census. This was a field operation to contact households for which receipt of census forms had been recorded, but for whom completed census forms in either physical or electronic form had not been received and registered in the records database. The supplementary inquiry was performed exclusively by enumerators working under the instructions of the CZSO and holding special authorisation.

For the purposes of this inquiry, only dwelling households from whom no form had been received were considered. A list of address of these households was set up, of which there were 152 thousand in total (342 thousand census forms) Such a quantity of contacts could not however be realistically processed in the limited time with the available capacity. A selection was therefore made according to the concentration in the number of households in the territory which it was realistic for the enumerators census commissioners to cover on foot for the supplementary inquiry. Inquiries were made on Census Form - Person and Census Form – Dwelling  distributed  during the formal census period and not yet submitted in any way. Census Forms – Bulildings were not the subject of supplementary inquiry.

The outcome of the supplementary inquiry was the acquisition of 45.5 thousand completed forms. A side effect of the inquiry was the acquisition of forms from several hundred people who were not part of the selection. For example, people who learned about the supplementary inquiry by chance, expressed an interest in being counted, and had not been included in the standard census, had not received  census forms nor sought them out, and individuals from households where the other members had given in forms, etc. The renewed interest in submitting census forms was aided by promotion of the supplementary inquiry in the media.

The census data disseminated by Eurostat are addressed to policy makers, researchers, media and the general public.

No user satisfaction surveys are carried out. User inquiries are handled by the Eurostat User Support service.

Depends on the availability of data transmitted by the National Statistical Institutes.

Census Day 26.3.2011, data transfer data (hypercubes) 31.3.2014. Time interval between data availability and census date 1101 days (27 months, as defined in European Parliament and Council (EC) Regulation No. 763/2008, Art. 5).

Data transferred by the CZSO are fully comparable across all territorial levels. All processing was performed on the basis of EU standards in respect of census scope, definitions, unit and classifications.  

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.

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).

Census Budget

Preparation of the census budget began in connection with development of the main principles and concept of the 2011 Census in 2005. Implementation of the census project took place over the 2008 – 2013 period. In 2007 the CZSO also proposed a budget, which was approved by the government. Its original budget for the entire period was 2,648 million CZK, of which 2,519 million CZK were for the CZSO. This was less than the value of the census budget in 2001, if inflation between 2001 and 2011 is taken into account. The budget was reduced by a total of 137.3 mill. CZK by a Ministry of Finance ruling as part of an overall reduction in state budgetary expenditure. In addition further savings were made against this reduced budget. For the last two years of the project – 2012 and 2013 – the CZSO did not request the release of the set budget for these years and covered expenditure entirely from project savings in preceding years. It may be stated that compared to the original budget, total savings were made of 246 mill. CZK.

A major part of the expenditure on preparation and conduct of the census was implemented in the form of paying for completed public contracts. The largest value was for a public contract for supply of services associated with the distribution and collection of census forms, to the value of 756 million CZK, before VAT. The second largest public contract was for census IT at a value of 450 million CZK, before VAT.

The expenditures of central administrative offices linked to the census were budgeted in their respective budgets. Municipalities, regions and the city of Prague were entitled to special-purpose grants for expenditure associated with the preparation and conduct of the census.

The largest savings during the census were achieved in personnel costs – roughly 138 mill. CZK. The savings on salaries were mainly achieved from the fact that an unexpectedly high proportion of the population did not hand their completed census forms back to enumerators, but sent them to the P.O.Box. It was therefore possible to reduce the number of controllers who were to collect the forms from the field works supplier’s enumerators to roughly one-third. A further major saving arose at the coding facility, where thanks to the high efficiency of the automatic coding, and the higher performance of the staff, it was possible to finish the planned tasks using a lower number of staff and in one-quarter less time than planned. Similarly, at each stage of results processing savings were made on salaries.

Use of budget

Use of the census budget was governed by the general directive for managing budget resources as valid for state administration bodies. The census project was also affected by several other binding directives. In particular, the Directive on Managing Budget Resources for the 2011 Census, on the right to make use of such resources and certain other authorisations, adopted at the end of 2008.

Approval of the budget and use of all budget resources was within the purview of the Chairman of the CZSO, or the Representative Office member in charge. Budget resources for the census project were allocated  only for the purposes of the census and these resources were accounted for separately from other CZSO budget resources. Within the project team individual staff members were designated for the use of budget resources; the relevant activities, such as signing payment orders, administration of the budget, management of overall records, etc., were divided.

For the preparation and implementation of contracts (approval of plan, adoption of contract, acceptance of completed work) concluded by the CZSO with suppliers, specific working procedures were established. Work then underwent ongoing checks.

Measures leading to a reduction in demands on the budget

The key phase of the project was the distribution and collection of census forms. When preparing distribution, administrative data sources were used – Central Population Register (CPR) for partial pre-completion of personal data in the Persons census forms, Register of Census Districs and Buildingsthe Census Districts and Buildings Register for pre-completion of the House- and partly of the Dwelling Census Forms. Data from CPR was also used in other phases of data processing. The use of administrative sources helped to increase the completeness of the census and the quality of data, and contributed in a fundamental way to increasing the work efficiency of the enumerators and to reducing the demands put on respondents.

A major step in limiting demands on the budget was arranging for distribution and collection of forms using suppliers. Setting up a large number of collection spots, together with hiring temporary staff, would also have been costly and difficult to manage in terms of management and logistics. The Czech Post Office as the supplier of field services had the required capacity in human resources, technologies and infrastructure. A further advantage was that the functions of enumerators were performed mainly by post office staff with a knowledge of local conditions in a given census district.

All external census suppliers were selected using public tenders. The issue of public contracts was governed by the CZSO Directive on public contracts which refers to Act no. 137/2006 Coll., on Public Contracts.

Savings were also made because a major share/part of respondents used postal services (the mail-out method) for returning their census forms, which led to savings in manpower and thus to field services costs of 28 mill. CZK.

There was a very positive response to the option for submitting data using the Internet. Enumeration of 27.5% of all inhabitants, 22.8% of all dwellings, and 25.3% of all buildings were done in this way. The internet application supported form completion with help questions and a check on completeness and logical correctness. Thanks to the high share of electronic census forms the completion, primary datacollection and checking went more quickly than in the timetable. This was another source of savings.

From the very beginning the CZSO website served as the main source for providing census results to all users. Similarly, basic data publications were issued in both electronic and printed form. An electronic database of results down to municipality level is available as well; this – while complying with the requirements for personal data protection – permits further individual analysis in line with users’ needs. This reduction in printed publications also has an impact on reducing demands on the census budget.

The data being transferred in the form of hypercubes are correct and have not undergone any data revision. Nor has any data revision taken place for data provided to other users.

Data on population and housing censuses are collected every decade, in a reference year that falls during the beginning of every decade

Preparation of data collection was divided into several areas

1. Proposing and testing of questionnaires

The content of the questionnaires for the 2011 Census was based on the census content set out in Act No 296/2009, European Parliament and Council (EC) Regulation No 763/2008, but also on the needs of data users and state statistics in the Czech Republic. The final form of the census forms was established by an amending legal regulation to the Census Act, Decree No. 279/2010.

2. Field work preparation of the census

The purpose of territorial preparation was verification of the territorial structure – buildings, addresses and functional definition of housing estate locations of buildings, addresses and housing estate locations. Territorial preparation also permitted the creation of census districts, the preparation of documentation for the field work of enumerators and the creation of a managing set of territorial units for processing and summarising of census results.

3. Communication and Information Campaign

The reason for the campaign was the attempt to gain the public’s interest and support and so achieve maximum precision and completeness of acquired statistical data for the 2011 Census. The main purpose was to advise the wider public about the 2011 Census, to explain its purpose and significance and to build positive perceptions of the event.

4. Data collection (including field work)

Work in the field was conducted by the field work supplier, the Czech Post Office. In census districts of a specific nature, distribution and collection of forms was arranged by other partners – the Ministries of Defence, the Interior, Foreign Affairs and Justice. In large accommodation facilities the census was conducted by CZSO enumerators.

Field work was achieved through 681 collection points (selected branches) of the Czech Post Office, 14 regional and 82 distributed CZSO offices and 4 Ministries. There were 9799 census districts under the administration of the Czech Post Office, the CZSO conducted the census in 2109 districts and Ministries in 258 districts. In total the census required more than 23,000 field staff and further back-office personnel.

Form Distribution:

a) Distribution of paper forms (pre-completed and blank) to those to be recorded, through a enumerators

b) Electronic distribution

distribution of Census form – building to major property owners using their official databoxes

electronic census forms available at the census Internet application using an access code printed on the paper form.

c) Supplemental distribution of paper forms at Czech Post Office contact points, at municipal offices and at CZSO offices.

Completion of census forms was done using self-completion. The Internet application supported form completion with help questions and a check on the completeness and logical correctness of form completion.

Form collection:

a) Form collection by the enumerator from the person recorded.

b) Form collection by mailing to P.O.Box address

c) Electronic submission using an Internet application with a high level of data protection.

d) Electronic submission of completed forms using an official databox (large property owners).

e) Personal submission of completed forms at the counters of designated Czech Post Office branches or CZSO offices.

Data validation:

Records from administrative sources were added to data records acquired from census forms. This so-called linking of records took place in two steps: linking via personal identification number (including full agreement of name and surname), probabilistic pairing (assessing the level of agreement of name, surname, date of birth and personal identification number. Identification also took place in administrative sources of records for those people no longer living in the country. These records were not transferred to the census microdata database.

To be included in the census (input into the census microdata database) a record had to meet at least one of the following conditions:

a) The submitted census form matched an ISEO (Central Population register) record.

b) A pre-completed form intended for a given recorded person was successfully distributed to the household, but did not return.

c) The ISEO (CPR) record contained a change to one of the selected data over the last five years.

Meeting one of these conditions was taken as an indication that the recorded person in question is probably actually in residence in the country. A total of 274 thousand ISEO records were eliminated from further processing for failing to meet these criteria. A further 419 thousand ISEO records which were not linked to a submitted form were used to extend the set of people counted.

Imputation of records into any of the primary sources was not performed; the resulting set of persons arose through record consolidation.

Data processing

Deduplication and prioritisation followed data linking. Prioritisation represented the selection of a particular indicator in cases where a given record/item was available from multiple sources. In principle, priority was given to data from forms over data from an administrative source, where the datum on a form was not evidently nonsensical. A series of checks served to assess the meaningfulness of data. Following deduplication and prioritisation a set of data records was formed to go into further processing.

Data processing included:

a) Data coding (subsequent scanning and digitisation of forms, text recognition, verification, validation and export to the processing database), deduplication and prioritisation of records and individual data.

b) Feasibility checks evaluated the input values in respect of expected value intervals, or codes in the relevant table. Corrections to inadmissible values were made using autocorrection.

c) Stating the usual residence of people was crucial for data processing. Based on questions in the form and the permanent residence address taken from an administrative source a specific address was derived to serve as the basis of further processing and the basis for preparing outputs for the usual place of residence of the inhabitants.

d) According to the normal residence address further data records were linked for persons, dwellings and buildings. In the Census form - dwelling information was determined in the field on relations within a functioning household. After data records were linked these declared relations were verified (forming the basic input for determining the type of household, or family). In the case of missing information on relations within a functioning household, these relations were constructed using information from an administrative source. Within this processing subsystem duplicates of building and dwelling records were also evaluated.

e) A process of logical checks verified the data logic for mutual relationships, both within a single entity (responses from a single form) and within two entities (e.g. the logic relationships between data on dwellings and data for a particular building). Logical checks were aimed mainly at improving data quality. Repairs or removal were done using autocorrection.

f) So-called indicator derivation secured the transformation of input data into output, evaluated missing responses and processed new information according to prescribed algorithms. Derivation was integrated with the SMS subsystem, which was the source of metadata descriptions for the individual transformations. The independent algorithm was for deriving the kind of household, or family in the case of people living in the household. Outside households there were the homeless and those in institutions (these persons did not meet the conditions for a functioning household). Processed independently were data on so-called commuters flows which are vectors of two territorially differing addresses with counted frequencies of the characteristics of working people or school pupils, students and apprentices commuting from their place of residence to a workplace or school.

Following the populating of the processing database with data, the processing of pre-defined outputs followed – for publication output or website presentation.
