Demography (gr. demos – people, grafein – describe) is the social science dealing with the study of reproduction of human populations.

The object of demography: human populations

Population (lat. populus – people) is the social formation encompassing human beings with individual qualities, living in a given geographic area or space, and the reproduction taking place among them.

The focus of demography: demographic events (phenomena) and processes related to the reproduction of human populations.

Demographic events include: marriage, birth, abortion, death, divorce, migration (change of the address of residence).

Demographic processes are: nuptiality, natality, abortion, mortality, divorce, migration (The demographic process – a process where demographic events are registered and monitored as collective phenomena).

Demographic statistics is the basic method of demography and represents the specialised activity for the collection and processing of quantitative population data.

The object of demographic statistics: the individual (inhabitant)

The focus of demographic statistics: quantifying of demographic events and processes

The system of demographic and international migration statistics in the Slovak Republic

The system of demographic statistics in the SR is based on monthly processing of data on demographic events drawn from the exhaustive population survey and regularly performed censuses of population and housing.

I. 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 SR by means of statistical reports:

• Statistical Report on the Conclusion of Marriage
• Statistical Report on Birth
• Medical Report and the Statistical Report on Death
• Statistical Report on Divorce
• Statistical Report on Change of the Address of Residence/Report on Migration Migration

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, courts, residence registration offices of municipal and city authorities, departments of the Ministry of Interior of the Slovak Republic for the registration of foreigners, and a special registry office for the registration of the vital events that occurred to SR citizens abroad.

II. DATA PROCESSING

Demographic 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 marriages, divorces, births, abortions, deaths, migration, and population growth and population numbers by sex (basic absolute and relative indicators).

Monthly data presented during the reference year are the preliminary data; they are updated continuously (monthly) until the conclusion of the statistical processing of annual results.

Concerning annual statistical processing, databases of final micro-data on each demographic process in the reference year are created and used for:

• balancing population change by sex, age, marital status, highest educational attainment, country of birth, citizenship and nationality,
• producing multidimensional tables on demographic processes,
• producing special outputs, e. g., life tables.

III. SUPPLYING AND PRESENTATION OF DATA

The public database ´DATAcube.´

Demographic results of monthly and annual statistical processing presented in the form of multidimensional tables in time series (http://datacube.statistics.sk/#!/lang/en). The data are processed for the SR, urban/rural, areas, regions, districts and municipalities.

Demographic source books (´The Population Change in the SR´)

Detailed tabulated results (cross-tables) on the population change in the SR for the reference year, including data on marriages, divorces, births, abortions, deaths and causes of death and migration.

Publications

The ´WE IN NUMBERS´ edition annually presents basic information compiled from statistical data on the results of demographic processes in the SR in the publication WE IN NUMBERS – Population change and basic information compiled from statistical data on the results of international migration in the publication WE IN NUMBERS – International Migration.

The ´STATISTICS IN CONTEXTS´ edition presents analytical publications dealing with the population development and demographic processes:
