3.1  Data description

Population data cover persons with permanent residence in the territory of the Slovak Republic (SR citizens and foreigners granted permanent residence permit in the Slovak Republic).

Permanent residence is person´s permanent 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).

 

Data are disseminated on stocks, flows and structures of population with permanent residence in the Slovak Republic.

In the Slovak Republic, demography statistics is built upon results of population censuses carried out once every 10 years. In the intercensal period (i. e. between two subsequent censuses), the Statistical Office of the SR processes and publishes data on the population number and demographic structures for individual reference years on the basis of the continuous data updating performed by means of the balancing method. The data on the structures by sex and age are processed for the end of the year (31 December), broken down from the republic level (NUTS 1) to the municipality level (LAU 2), as well as for the mid-year (since 2011, the arithmetic mean of starting (1 January) and final (31 December) stocks of population.


3.2  Classification system

International standards: Data are compiled consistent with Regulation (EU) No. 1260/2013 of the European Parliament and the Council of 20 November 2013 on European Demographic Statistics as well as with Regulation (EC) No. 862/2007 of the European Parliament and of the Council of 11 July 2007 on Community statistics on migration and international protection and repealing Council Regulation (EEC) No. 311/76 on the compilation of statistics on foreign workers as well as with their implementing regulations.


3.3  Sector coverage

  • Population group coverage: Data cover persons with permanent residence in the Slovak Republic.
  • Geographical coverage: Data are processed for all municipalities (LAU 2) of the Slovak Republic and grouped by 4 areas (NUTS 2), 8 regions (NUTS 3) and 79 districts (LAU 1). 
  • Topical coverage: Data are compiled by sex and single year of age, and age group.


3.4  Statistical concepts and definitions

Permanent resident population (de iure population):

persons with permanent residence in the territory of the Slovak Republic (citizens of the Slovak Republic and foreigners granted permanent residence permit in the Slovak Republic).

11.2  Quality assessment

The data collection and processing of demographic statistics in Slovakia is conducted in accordance with the Quality management system of the Statistical Office of the Slovak Republic. The SO SR holds certificate of the quality management system according to ISO 9001:2015

The compliance of the Quality Management System with the requirements of the ISO 9001:2015 standard was confirmed by recertification audit by Bureau Veritas Slovakia in November 2018. The successful audit reaffirmed that the quality management system introduced in the SOSR creates the appropriate conditions for further improvement of the products and services provided to the customers and for the development of the office towards greater efficiency and effectiveness.

Quality manual

Methodological notes are included in all relevant population as well as in population databases.

The Slovak Republic has a high quality of demographic data because they are based on the results of the most recent Census of Population and Housing, updated every year by results of a regular, continual and exhaustive demographic survey on all vital events and migration, covering the whole territory/population of the SR. Civil registration system, health institutions and residence registration authorities are obliged by law to register and report to the Statistical Office on all occurred vital events and cases of migration.

The Census of Population and Housing was an exhaustive survey – i.e. covering each person in the territory of the Slovak Republic. It was based on the method of self-enumeration. In 2021, it will be implemented for the first time by the combined method, i. e. data will be obtained by self-enumeration as well as from administrative sources.

  • Population group coverage: Data cover persons with permanent residence in the Slovak Republic.
  • Geographical coverage: Data are processed for all municipalities (LAU 2) of the Slovak Republic and grouped by 4 areas (NUTS 2), 8 regions (NUTS 3) and 79 districts (LAU 1). 
  • Topical coverage: Data are compiled by sex and single year of age, and age group; all vital events and events of migration, population stocks and structures. 

As regards the statistics on causes of deaths (CoD):

The quality of COD data is subject to the way in which the information on causes of death is reported and classified in each country (i.e. national certification and coding procedures). In general, all countries follow the standards and rules specified in the ICD, and the overall procedures for the collection of COD data are relatively homogenous between European countries (medical certification of cause of death, use of ICD).

However, national differences in interpretation and use of ICD rules exist and, as a result, important quality and comparability issues remain. Based on the report "Comparability and Quality Improvement of the European Causes of Death Statistics" countries work towards further improving certification and coding procedures.


Ongoing work is reported to Eurostat's Working Group "Public Health Statistics" (documents available on circabc).

The causes of death data are based on a regulation, which defines scope, definitions of variables and characteristics of the data.

All the statistical data usually requested by international institutions and national users are available. 


Data are transmitted as requested in Art. 4.1 of the Regulation No. 1260/2013.


13  Accuracy and reliabilityUp
13.1  Overall accuracy

Demography statistics is collected by way of statistical survey on population changes (vital events and migration) conducted each year by the Statistical Office of the SR by means of statistical reports OBYV 1-5/12. The survey covers the whole population of the SR including the foreign citizens who have been granted the permanent residence permit in the SR. It is an exhaustive survey conducted under the Programme of National Statistical Surveys imposing the reporting duty concerning all statistical surveys on reporting units. Demography statistics is built upon results of the Population Census. In the intercensal period (i.e. between two subsequent censuses), the number of population is calculated by means of the balancing method.

Demographic outputs of data processing from the monthly population survey covering the total SR population provide reliable population data, therefore, it is not necessary to calculate population estimates or estimates of individual demographic characteristics for the Slovak Republic.

 

Register of foreigners data on are obtained from the Mninistry of Interior of the SR (all foreigners are covered); the data on foreginers are registered with the exact date of the entry into force / expiration of the stay permit.

Asylum seekers and refugeesthey are not involved in the number of population of the Slovak Republic. Persons with granted asylum in the Slovak Republic have permanent residence in the territory of the Slovak Republic and they are involved into the number of the SR population.

Register of acquisition and loss of citizenship the data are obtained from the Mninistry of Interior of the SR (all cases are covered).

14  Timeliness and punctualityUp
14.1  Timeliness

Population number no later than 12 weeks after the end of the reference year.

Population structures no later than 4 months after the end of the reference year.

Data for Census years are published with the time delay of up to 3 months.


14.2  Punctuality

Not applicable.


15  Coherence and comparabilityUp
15.1  Comparability - geographical

The level of geographical detail of demographic survey results is processed in accordance with the Commission Regulation EU No. 31/2011 amending annexes to Regulation (EC) No 1059/2003 of the European Parliament and of the Council on the establishment of a common classification of territorial units for statistics (NUTS).

There is a 100% comparability of statistics among geographical areas from LAU 2 up to NUTS 1 according to the NUTS classification. The data are aggregeable, i. e., data for higher territorial levels are obtained by aggregating data for lower territorial levels.


15.2  Comparability - over time

The data on the number of population, live births, deaths, immigrants, emigrants are available since 1920 (time series).


15.3  Coherence - cross domain

The Statistical Office of the SR is the only provider of population stocks figures for all other national statistics.


15.4  Coherence - internal

In the Slovak Republic, demography statistics is built upon results of the Population Census. In the intercensal period (i.e. between two subsequent censuses), the number of population is calculated by means of the balancing method:

Population on 31 December = Population on 1 January + Live Birth from 1 January to 31 December - Deaths from 1 January to 31 December + Immigrants from 1 January to 31 December - Emmigrants from 1 January to 31 December

Demographic statistics is internally coherent: it uses the same data sources (exhaustive demographic statistical surveys with monthly periodicity), statistical processing methods and definitions of demographic indicators.

Statistical surveys are carried out on the basis of valid, internationally comparable statistical code lists according to EU statistical standards. In order to achieve comparability of demographic indicators within the European Statistical System, the data are processed for the national (NUTS 1), the regional (NUTS 2 and NUTS 3) and the local (LAU 1 and LAU 2) levels. For the purposes of countries designation and for the purposes of processing data on international migration, the country-code list after the international standard ISO 3166-93 is used. Data on causes of death are processed after the 10th International Classification of Diseases and Related Health Problems (ICD - 10).

18  Statistical processingUp
18.1  Source data

Source data collection programs

  • Base estimates: The population data reflect the results of the most recent Census of Population and Housing, updated every year.
  • Population Census: A Census of Population and Housing was conducted as of 21 May 2011.
  • Births and deaths: The base for vital demographic statistical surveys is the system of civil registrations of all born children of mothers with permanent residence in the Slovak Republic, and civil registrations of deaths of persons with permanent residence in the Slovak Republic, and a special registration of the vital events that ocurred to SR citizens abroad.
  • Migration: The statistical forms completed in the case of change of permanent residence (in the country or at immigration from, or emigration to foreign country) are used for migration statistics.

Source data statistical techniques

  • Reference dates and frequency: Data are disseminated for a year end (31 December) reference date or, if appropriate, for shorter time periods (i. e. monthly, quarterly data, mid-year).
  • Time adjusted estimates: The data reflect the results of the most recent Census of Population and Housing, updated annually, based on the results of the statistical surveys on vital statistics and migration made by the Statistical Office of the Slovak Republic.
  • The results of the surveys are processed monthly. The dates of occurrence of demographic events (births, deaths and changes of permanent residence), not the dates of the civil registration of demographic events), are used in compiling population data.


18.2  Frequency of data collection

  1. Monthly – statistical surveys on the conclusion of marriage, birth, death, divorce, migration, abortion
  2. Every 10 years – Population and Housing Census

18.3  Data collection

Demography statistics is collected by way of statistical survey on population changes (vital events and migration) conducted each year by the Statistical Office of the Slovak Republic (SR) by means of statistical reports OBYV 1-5/12. The survey covers persons with permanent residence in the territory of the Slovak Republic (SR citizens and foreigners granted permanent residence permit in the Slovak Republic). It is an exhaustive survey conducted under the Programme of National Statistical Surveys. The Programme of National Statistical Surveys is a legislative document imposing the reporting duty concerning all statistical surveys on reporting units according to § 18, Par. 3 of Act No. 540/2001 Coll. on State Statistics as amended.

Demography statistics in the Slovak Republic covers the following demographic events: birth, marriage, divorce, change of address of permanent residence and death. The data are collected from the reporting units including municipal and city authorities in charge of keeping birth, marriage and death registers (i.e. registry offices), health institutions, competent courts, residence registration offices of municipal and city authorities, competent departments of the Ministry of Interior for foreigners. There is also a special register of the vital events that occurred to Slovak Republic´s citizens abroad.

Demographic data are drawn from the following reports on demographic events for each person with permanent residence in the Slovak Republic:

OBYV 1-12 (Statistical Report on the Conclusion of Marriage)

OBYV 2-12 (Statistical Report on Birth)

OBYV 3-12 (Medical Report and the Statistical Report on Death)

OBYV 4-12 (Statistical Report on Divorce)

OBYV 5-12 (Statistical Report on Change of the Address of Permanent Residence/Report on Migration)

From 1958, demography statistics includes also data on spontaneous and induced abortions. The data are drawn from the information system of the Ministry of Health. The National Health Information Centre under the Ministry of Health produces the abortion data by means of processing the form ´Application for Abortion and the Report on Abortion´.

The population census data are the basis for the demographic statistics in the Slovak Republic in the intercensal period  i. e. demographic statistics is updated every 10 years according to results of the most recent census.


 


18.4  Data validation

Information on each demographic event is recorded in an individual paper-based statistical report ´OBYV´. Reporting units send the collection of individual paper reports for each reference month on a monthly basis to the Statistical Office of the SR for the electronic processing: data from the paper reports are recorded in the Integrated Statistical Information System (ISIS). When recording data in the ISIS, automated checks of accuracy, consistency, and completeness of data are performed (e. g., logical checks focused on logical links/relations among particular information according to technical project documentation for the processing of demographic statistics). The source database containing microdata on population is created. The quality of demographic data is suppported also by the use of internationally harmonised statistical code-lists in the processing of statistical outputs.


18.5  Data compilation

The data reflect the results of the most recent Census of Population and Housing, updated annually, based on the results of statistical surveys on vital statistics and migration conducted by the Statistical Office of the Slovak Republic.

The results of the surveys are collected monthly. The dates of occurrence of demographic events (births, deaths and changes of permanent residence), not the dates of the civil registration of demographic events), are used in compiling population data.

Processing of demographic data is performed under the integrated statistical information system (ISIS) encompassing the following three databases: the source database, the production database and the public database. The source database is loaded with primary data, the production database with outputs from primary data processing, and the public database is opened to external users, e.g. bodies co-operating with the Statistical Office of the SR, such as the Ministry of Health, the Ministry of Interior and the Ministry of Justice.

The data processing has the following phases:

  • recording and checking data from the OBYV 1-5/12 reports
  • loading data into the source database
  • processing outputs for the production database
  • production of output tables and of other aggregates

 

Demography statistics is processed continually, separately for each month and for the whole year.

 

Data on population change are processed in monthly statistical processing, and, as a result, the following outputs are available:

  • statistics on population change (basic absolute and relative indicators, population growth and population numbers by sex for a given period)
  • tables on individual demographic events (statistics on marriages, divorces, births, abortions, deaths and the change of permanent residence)
  • specific age-related indicators for concerned persons (e.g. fiancés, mothers of the new live-born, the dead, divorced couples, females who have undergone abortion, etc.)

 

Concerning annual statistical processing, ´annual files´ are produced by aggregation of ´monthly files´. The annual files are used for:

  • balancing population change (by sex, year of birth, territory where the person was born, marital status, ethnic nationality, country of birth, citizenship)
  • producing aggregated table files for the presentation and publication purposes (e.g. the age structure of the population)
  • producing a file of combining tables (the demographic source book)
  • producing special outputs such as life tables, marriage tables, etc.

 



18.6  Adjustment

The methodology and content of demographic statistics are internationally comparable. The processing by classification point of view is done according to valid, internationally comparable statistical code lists according to EU statistical standards.  

Demographic outputs of data processing from the monthly population survey covering the total SR population provide reliable population data, therefore, it is not necessary to calculate population estimates or estimates of individual demographic characteristics for the Slovak Republic.
