Preliminary annual data on population and vital events are available in t+30 days, final data are released at the end of June after the reference year.

Preliminary vital events data are published on a monthly basis with First releases. Preliminary annual data as well as final annual data are released on HCSO website under the Data - Stadat link. The Statistical Yearbook is published in August, while the Demographic yearbook is available in October.

Monthly first releases are published on the preliminary data of vital events.

The most comprehensive publication is the annual Demographic yearbook, covering all fields of demography, available in Hungarian and English. A wide range of population and vital events data are released in the annual Statistical Yearbook as well.

On HCSO website a Dissemination database is available with large quantity of demographic data. Users can compile the most relevant data in an interactive manner, choosing the variables and the structure of the tables.

Fixed tables are also published on the website presenting the most important numbers, these tables are available under Data - Stadat points.

Statistics are prepared in line with the principles of the European Statistical Code of Practice. The Hungarian Statistical Office has a publicly available Quality policy. For the statistical production process Quality principles were prepared in line with the EUROSTAT requirements and recommendations. As for product quality Eurostat Quality reports are filled in for certain statistics as well as the calculation of quality indicators. A documentation sheet is filled in annually for all subject-matter statistics covering main methodological information.

Annual population data are based on the fully comprehensive data of the last census. Annual vital statistics are also prepared on the basis of a fully comprehensive registration system, while during processing dual record check is applied, therefore providing data in good quality. International migration statistics are estimated with the use of all relevant administrative data sources, providing reliable data to the highest possible extent.

Quality aspects are described in the publicly available metadata of subject-matter statistics.

All user needs (including unsatisfied ones ) are registered in the system of the Hungarian Statistical Office. By completing them with data of downloads from the website, we have comprehensive information on user needs, which are taken into account during the design of dissemination products. Concerning population and vital events data, the annual Demographic Yearbook offers a wide range of data, which fulfill most of user needs.

Data are published as soon as they are available, i.e. preliminary data are available at the end of January, while final data are published at the end of June.

Data publications follow the dates previously disclosed in the release calendar.

Geographical breakdown of population data is in line with NUTS classification, therefore internationally comparable.

The different subject-matter statistics use the same population estimates, assuring high level cross-domain coherence.

Data are coherent.

The general principles of HCSO’s data revision policy statistical data in HCSO can be found at: http://www.ksh.hu/docs/bemutatkozas/eng/ksh_revizios_politikaja_2018_eng.pdf

For the time being, description of data revisions are available for every subject-matter statistics at: http://www.ksh.hu/apps/meta.main?p_lang=EN&p_session_id=24716643

For annual demographic data, preliminary data are available t+30, while final data are published at the end of June after the reference year.

Major revisions:

For population data, back- and forward revisions might be carried out after censuses, depending on the size of differences between estimated and census data, which is due to methodological reasons. The discrepancies may require retrospective correction of the population estimates on the basis of census data. This revision might be made every ten years. A revision of the entire inter-censal period (between 1991 and 2000) was based on the census of 1 February 2001. After Census 2011, only the population estimate for January 2012 was adjusted. The reason for this was the conversion to the new, 2011 census base.

Collection of vital events data is continuous. Migration  datasets are transmitted from dataowners on a quarterly base regarding migration data of Hungarian citizens while in connection with foreign citizens data are transmitted on a monthly base.

Data of live birth statistics are collected by civil registrars and health institutions, death statistics are collected by civil registrars. Migration data are transferred from different administrative data sources with different frequency (see 18.2.).

During data production processes, quality and consistency checks (e.g. dual record checks) are carried out in order to handle logical contradictions and errors.

As for live births statistics, data sources are collected by civil registrars and health institutions, while deaths statistics data are collected by civil registrars and than compiled by the Hungarian Central Statistical Office. Coding, editing and imputation are carried out by the HCSO, and then the final, verified data are loaded into the internal Demographic database.

In case of migration data, input data are transmitted from different administrative organizations as the Population and Address register, and registers of the National Directorate-General for Aliens Policing, and the National Health Insurance Fund. Datasets are linked by the HCSO, then cleaned from duplications and estimations of stocks and flows are made

The reason for the statistical adjustment is that population, vital and migration statistics data are compiled from several separate data sources (i.e. civil registrars, health institutions, HCSO statistical data collection on vital events, Population register, National Directorate-General for Aliens Policing, National Health Insurance Fund), which are not fully harmonized.
