According to Regulation (EC) of the European Parliament and of the Council, the 2011 population and housing census was held for the first time in all EU Member States in the same year, using uniform or similar definitions of surveyed data. It was part of a global program of the population and housing censuses, which, in collaboration with Eurostat, was coordinated by the United Nations. In the Slovak Republic, there has been a conventional census; the content, scope and method of its conducting was established by law. Residents were allowed, for the first time in history, to choose whether to fill out the Census Sheets in paper or electronic form by the Internet. The population and housing census was conducted as of the 21st May 2011. The census date was midnight between Friday the 20th of May 2011 and Saturday the 21st of May 2011. The data obtained from the population and housing census are: 1. unique (in the Slovak Republic, the data may not be currently obtained otherwise only by cooperation with residents), 2. indispensable (help to create a coherent picture of the society, its demographic, social, cultural, educational and economic level, the structure of households and housing fund), 3. used in all areas of social life from the highest territorial levels down to municipalities, in current policies and in developing long-term strategies.

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 is considered as temporarily absent persons and thus included in the total usually population. In contrast, persons living or expected to live outside the place of enumeration for one year or more is not considered temporarily absent and therefore is 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.

The Slovak Republic assesses usual residence as a place of permanent residence, i.e. by the registered residence. Permanent resident population (de jure population) include residents who have at the census reference date permanent residence in the Slovak Republic and have intention to live here 12 months or more. Permanent residence is person´s pernament place of abode. It is municipality in which citizen of the Slovak Republic, or foreign citizen stays according to official registration, i.e. signing up for permanent residence (Act. No. 500/2004 Coll. and Act. No. 48/2002 Coll. in wording of later regulations).

Sex is a biological feature of all individuals, whether male or female.

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 is classified according to his/her most recently acquired legal marital status at the reference date. In the Slovak Republic these types of marital status are legal: single, married (the minimal age for marriage is 18 years, in specific cases it is allowed from 16 years), divorced (no extra limitation for divorces) and widowed. Registered partnerships and same sex marriages are not legal in the Slovak Republic.

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 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 is enumerated in the household of at least one of the parents, and who has no partner or own children in the same household.

According to the national classification of Local Administrative Units (LAU2, municipalities), the capital City Bratislava and Košice (second biggest city) are composed of city parts. The ´city part´ administers the self-government and to this extent it has the status of municipality. For information about the capital city Bratislava (and also Košice) as one single territorial unit, it is necessary to sum data for all 17 city parts of Bratislava (and all 22 city parts of Košice). 

Data refer to the situation in the reporting country at the census reference date (see item 5)

Content, scope and method of census in Slovakia are defined by individual law. According to Act no. 263/2011 Coll. on the 2011  population and housing  the census reference date was midnight from Friday 20 May 2011 to Saturday 21 May 2011. Data actually to the census reference date were written in the census forms (A. Data on population,  B. Data on apartment, C. Data on housing) by citizens themselves. The 2011 census was conducted as conventional census by self-enumeration. All Slovak citizens and foreigners residing in the territory of the Slovak Republic except foreigners having diplomatic privileges and immunities had an obligation to provide data for census purposes, owners and managers of flats or tenants for each residential buildings or other building that was occupied at the Census reference date, except diplomatic missions of foreign countries and the owners or managers of the flats, tenants or subtenants.
Census is managed, methodologically controled and coordinated by Statistical Office of the Slovak Republic in cooperation with applicable central government authorities, district offices, municipalities and higher territorial units. Content of Census forms reflects Regulations of the European Parliament and the Council, the Conference of European Statisticians Recommendations for the 2010 censuses and national requirements. The Statistical Office proposed form and content of the census forms, which were subject of consultation exercise among the office staff, experts (sociologists , economists, statisticians, etc. ), colleagues in government departments and pilot census. Action of Statistical office Slovak Republic No. 438/2010  constitutes specialities about characteristics, basic signs and structure of collected data and publish indent of census sheet for the 2011 Population and Housing Census. Slovakia was divided into 19,756 census tracts (territory of the municipality/part of municipality in which the census was conducted), which ensured the data collection by about 20,000 census enumerators.
Census tracts were created by district offices by the draft of municipality through a web application. The starting point was boundaries of the 2001 census tracts.
At the Census period (from 13 May 2011 to 6 June 2011) census takers  delivered to households census forms and  identifiers and took back completed forms. Population was for the first time allowed to complete census forms in paper form or electronically (from 21 May to 29 May 2011) through a special website.
Census forms were in the state (Slovak) language and on ethnically mixed areas have residents also available census forms in the languages of national minorities (Hungarian, Roma, Ukrainian and Ruthenian) and in English. After completion of data collection municipalities completed census forms and other census material from the census enumerators. Municipalities submitted whole agenda to district offices and than to the regional office of the Statistical Office. In the middle of June 2011 Statistical Office started data processing (scanning, coding, etc.).

Data validation was performed on the basis of the data obtained after scanning the paper census forms of population, houses and dwellings and merging them with electronic forms. It was followed by transformation into a database form and removal of duplicates (for example persons, dwelling and houses counted both through a paper form and electronic form). After this process, the obtained data on population were compared with data from demographic statistics. The obtained data on housing were compared with the statistics new, under construction and completed dwellings.

The primary database called "ZBER" (collection) was created by merging the paper and electronic versions of the census forms. Next step was data coding, which converted verbally recorded information to the classification schemes according to statistical code lists. It was followed by items imputations (occupation, current activity status, status in employment, industry etc.) and logical checks aimed at the logical links of information on the population, housing and dwellings conducted according to technical projects. After correcting irregularities detected, secondary items were derived (age, duration of current marriage, size groups of municipalities, etc.). The last phase was the generation of households by matching data on population, housing and dwellings. As a result, the final database called ZBD_SODB_2011 (microdatabase) was created.
