  1. The Use of Administrative Sources for Statistical PurposesAdministrative Sources and Statistical Registers

  2. Direct Use • Simplest case - an administrative source is used directly as a sampling frame • Easy and cheap • Quality problems? • Lack of control?

  3. Indirect use (1) • One or more administrative sources are used to construct a statistical register • A statistical register can be a tool for integrating data from different sources

  4. Indirect use (2) • A statistical register can contain additional variables, e.g. from surveys, imputed, or calculated • The statistical register is owned and controlled by statisticians

  5. Multiple data sources • Data from a single source • no check on accuracy • Data from several sources • better view of the accuracy of the data • increased range of variables available • but; how to deal with data conflicts?

  6. Models for Creating and Maintaining Statistical Registers using Administrative Data

  7. UK Business Register

  8. Basic Registers in Sweden

  9. Central Register • Cross-government projects to create central registers of person / business data to facilitate data sharing, e.g. • Registers in Nordic Countries • Australian Business Register • UK Business Index

  10. Case Study - ABR • The Australian Business Register (ABR) is developed and maintained by the Australian Tax Office • Web interface (www.abr.gov.au) • Businesses can register, amend details and file returns on line • Free access for Australian Bureau of Statistics

  11. Case Study - ABR (2) • The Australian Bureau of Statistics has a two-tier statistical business register • Most records are direct copies from the ABR • Only the largest and most complex business structures are maintained by the statistical office • This allows statistical resources to be used where they are most needed

  12. Case Study - UK Business Index • New project to create a basic central register of businesses • Partners: • Office for National Statistics • Tax office • Company registration agency • Local authorities • Specialist agencies e.g. environment, health and safety

  13. Business Index Model

  14. Using Administrative Data in SatelliteRegisters

  15. What is a satellite register? The Eurostat Task Force on satellite registers on distributive trade said:- A satellite register is a register of units which belongs to the national statistical system, and fulfils the following conditions:

  16. 1. Satellite registers are not part of main statistical registers, but are closely linked to them; 2. Satellite registers are more limited in scope than main statistical registers, but within their scope they may have better coverage;

  17. 3. Satellite registers contain one or more characteristics that are not found in main statistical registers, especially stratification variables; 4. Satellite registers should be distinguished from those databases in which results from surveys are normally recorded

  18. So a satellite register is a tool for incorporating administrative data that are only relevant for a sub-set of units in a statistical register Satellite registers may contain additional units, or variables, or both Satellite Register Statistical Register

  19. Examples in Practice • Tourism - hotel register (category, number of beds) • Transport - vehicle or ship register (type, capacity) • Distributive trades - buildings register (building size, sales area) • Military personnel – register of people serving in the armed forces

  20. Purposes of Satellite Registers (1) • Constructing more comprehensive sampling frames • Extending coverage of target populations • Providing additional stratification variables • Providing auxiliary variables to help estimate population totals

  21. Purposes of Satellite Registers (2) • Providing variables that can supplement or replace those collected through surveys • Improving the quality of information already in the main register, therefore reducing costs and the response burden

  22. Group ExerciseCreating a Statistical Register of Entrepreneurs

  23. Case Study:Statistical Business Registers in the European Union

  24. Background (1) • EU Regulation (2186/93) - Business registers for statistical purposes are compulsory in all EU Member States • The Regulation lists compulsory and optional variables • The latest version includes enterprise group variables

  25. Background (2) • It is unlikely that all variables are available from one source, so multiple sources are needed • The use of administrative sources is encouraged • The choice of sources is left to Member States

  26. Background (3) • Eurostat collect information on sources used and data quality via an annual questionnaire • The UNECE sends the same questionnaire to countries that are not members of the European Union

  27. Sources used for Business Registers in European Union and Candidate Countries(Slides from Eurostat / UNECE)

  28. Number of Sources Used

  29. % of Countries Using Each Source

  30. Comparison: Balkans and Former Soviet Union

  31. Sources of information on Enterprise Groups
