  3. 1. History of census taking The history of population censuses held in Belarus was closely linked first to Russia and then to the USSR, of which Belarus was a member. The first general population censusin Russia was conducted in February 1897. In the territory of Belarus resided6 673 000people, of whom 5 774 000 rural (87 %) and 899 000 urban (13 %) .

  4. 1. History of census taking • Censuses conducted in the territory of Belarus while it was part of the USSR: 1926, 1939, 1959, 1970, 1979, 1989

  5. 1. History of census taking Each census made an important contribution to the development of demographic and statistical theory and practice • Based on the1926census the first demographic projections and detailed mortality tables were made. • In the1939census, control forms and enumeration certificates were used for the first time. • The1959and1970censuses used punch-cards and computers; a combination of exhaustive and sample enumerations was introduced, whichreduced the costs of the census operation and shortened the period of data processing. • In1979a new census questionnaire was brought into use: responses were entered with graphic symbols and only selected ones in words.

  6. 1. History of census taking • The1989 census – the last Belarusian census within USSR. Afterwards a new history took its rise - the history of national censuses. • In February1999,the firstnational population censusof the Republic of Belarus took place.Only one population category – the permanent population- registered.No sampling, the total population questioned.The observation unit - household.

  7. 2. Census documentation • Census documentation includes specially developed and validated instruments intended to collect data from the population and prepare those for processing in accordance with the census programme.

  9. 2. Census documentation • Census questionnaires: • form 2П - "List of those usually (permanently) residing in dwelling and their housing conditions " - 7 questions; • form 3Н - "Census questionnaire " - 17 questions; • form 4И - "Census questionnaire for those temporarily present in the territory of the Republic of Belarus " - 7 questions; • Instructions on conducting the 1999 Population Census and filling in the enumeration forms.

  10. form 2П - “List of permanent residents in dwelling and their housing conditions"

  11. form 3Н - “Census questionnaire"

  12. form 4И - “Census questionnaire for temporarily present"

  13. 2. Census documentation • Instructionsare the methodological basis of the census.They determine the time schedule and methods of the census taking, the procedure of filling in enumeration questionnaires, categories of the population to be enumerated, and the unified rules of recording answers to the census programme questions.

  14. 2. Census documentation To prepare the enumeration questionnaires for machine processing the following classifications were used: • Countries of the World • Nomenclature of Administrative and Territorial units and Settlements • Glossary of Nationalities and Languages of the Republic of Belarus • Alphabetical Index of Occupations • Register of the names of streets • Codebook

  15. 3. History of census microdata, availability and accessibility (use by external users). • The central database containing all census data – the key component of the information system. • The population census data are stored independently at two levels: republicandregion.

  16. 3. History of census microdata, availability and accessibility (use by external users). • Republic level(Oracle ) : all microdata of the 1999 Population Census of the Republic of Belarus. • Region level(Visual FoxPro): microdata of regions. The data bases contain all data collected in the 1999 Population Census in a structured form.

  17. 3. History of census microdata, availability and accessibility (use by external users). Methods of data dissemination: • production of essential tables on paper; • production of equivalent tabulations for machine-readable media (magneto-optical disks, CD-ROM); • production and reproduction of spreadsheets (inExcel format)

  18. 3. History of census microdata, availability and accessibility (use by external users). Automated preparation of subject pages to be disseminated via Internet ensures: • storage of compiled census results as PDF files; • retrieval of required information from the warehouse of finished reports ; • transmit files retrieved through e-mail service of the global network Internet ; • production of statistical web-pages.The automated information system is GIS-compatible.

  19. 4. Contents of microdata files : variable for dwellings, households/families, persons • The information resource of the 1999 Population Census of the Republic of Belarus has a two-level structure with the central database containing all population census data at the first level and six population census regional databases at the second level

  20. 4. Contents of microdata files : variable for dwellings, households/families, persons • Special divisions in six regional statistical offices to manually enter data to the regional microdata bases organized in the Visual FoxPro environment. • The regional databases integrated into the central database developed in the Oracle environment to contain all population census microdata.

  21. 4. Contents of microdata files : variable for dwellings, households/families, persons • The primary unit - individual person • The secondary unit – household Simple (sequential) sampling to select every tenth household. • The sample unit - private household Total sample size - approximately 1000000 personal records in 385502 households.

  22. 4. Contents of microdata files : variable for dwellings, households/families, persons Three base tables in dbf-format: The first tablecontains source information on each sample household: • type of ownership • number of occupied rooms • useful and living floor space The second tablecontains source information on housing units occupied by sample households: • type of housing unit • period of construction • construction material of outer walls • facilities of housing unit

  23. 4. Contents of microdata files : variable for dwellings, households/families, persons The third tablecontains source information on individual persons comprising households: • relationship to reference member of household • serial number of mother in the list of residents • sex • age • place of birth • language (mother tongue, spoken language, other) • citizenship • nationality • marital status • educational attainment • source of livelihood • economic activity • occupation • status in employment • place of previous residence • children born alive, children surviving, children living separately (for women) • number of children the womanis planning to have

  24. 4. Contents of microdata files : variable for dwellings, households/families, persons The three tables have one common key attribute. In addition, the information is classified across the six regions of the Republic of Belarus by urban and rural. The large city criterion is also distinguished (100 thousand inhabitants and over). The structure of the base tables is shown in the codebook where each attribute is provided with the following information: • name of attribute (name of the base table field); • type and length of field; • list of values of attribute; if values are listed in indexes, a reference to the relevant index (glossary) is used; • statistical population: description of units, information for which is presented in the database (for example, the question on marital status was asked of persons aged 15 and over).

  25. 4. Contents of microdata files : variable for dwellings, households/families, persons The indexes are presented as tables in dbf-format: • territories; • nationalities; • languages; • countries; • occupations. The structure of indexes is shown in the codebook.

  26. 5. Harmonization: comparability with other censuses and with international standards • The main mission of the official statistics of the Republic of Belarus is development of a sound, scientifically justified statistical methodology and improvement thereof in accordance with the national and international statistical standards • The programme of the 1999 Population Census was developed following one of the key principles of official statistics - comparability of statistical data.The construction of questions was aimed at preserving historical consistency and facilitating chronological comparisons with previous population censuses.

  27. 5. Harmonization: comparability with other censuses and with international standards • The table below shows the comparability of the 1999 census programme with the previous census and recommendations of Eurostat:

  28. 6. Completeness of enumeration • “Control visits covering 10% of households”within four days after the census to check the work of enumerators and introduce corrections. • 42.7 thousand persons (0,4%) enumerated in addition and included in the results of the census.

  29. 6. Completeness of enumeration Assessment of the quality of the 1999 Population Census : • Visual check • Comparative analysis of the 1999 population census data and total population estimates based on the current vital statistics • Comparison of age groupings obtained in the census and in estimates based on the natural and mechanical population movement • Comparison of census results for a number of the population’s characteristics with other sources like current household surveys and existing data banks
