United Nations Economic Commission for Europe Statistical Division SPECA PWG on Statistics 2nd Meeting, 14 and 15 June 2007 Geneva United Nations Economic Commission for Europe Statistical Division Item 7: Requirements for the legal framework for the census Heinrich Brüngger. Director, Statistical Division UNECE Reference Material Appendix III of the CES Recommendations for the 2010 Censuses of Population and Housing - UNECE Statistical Division Slide 3 Relationship between census law and statistics law The census law can be simplified by an explicit reference to the statistical law for all matters for which no specific provisions are included in the census law However, this is only possible if the individual data from the census are for exclusively statistical use - UNECE Statistical Division Slide 4 Statistical use Check whether the statistical law contains a definition of statistical use that covers also indirect use for statistical purposes (e.g. through updating of statistical registers of persons, dwellings, buildings, or economic units, or through dierct use as sampling frame for surveys) - UNECE Statistical Division Slide 5 Avoiding non-statistical use in all phases of the census Censuses use staff and insitutions, notably at local level, which are not normally involved in official statistics and are therefore not very familiar with the confidentiality rules of official statistics For this reason, the census law needs to be more specific on this issue than the statistical law, and has to specify safeguards for all phases of the production, especially for the data collection and processing - UNECE Statistical Division Slide 6 Professional independence While the topics covered by the census may be fixed in the census law (which is not the case for other data collection activities of official statistics), the precise formulation of the question is to be decided by statisticians on the grounds of international standards and ease of response. The lessons learnt from the pilot census are a key element in the final decisions about the questionnaire - UNECE Statistical Division Slide 7 Professional independence (ctd.) Other items to be decided by statisticians without political interference: • • • • • Choice of administrative sources in various forms for completing and combining with the information collected dreictly from respondents Methods and strategies of editing, imputation and quality control of individual data Choice of aggregates to be released as results of official statistics from the census, including the terminology used in these tables Quality control of results Forms of dissemination - UNECE Statistical Division Slide 8 Dissemination Dissemination of census results should follow the same principles as dissemination of results from other sources of official statistics, i.e. to be fully under the umbrella of professional independence without any clearance of results by a committee or even government This is so fundamental that repeating in the census law what may already be contained in the statistical law is justified, if no discrepancies between the two laws are created - UNECE Statistical Division Slide 9 Dissemination (ctd.) Release dates to be announced in advance Simultaneous release to all users [Government may receive the release a few hours ahead of the official release if this is on the same day, for the exclusive purpose of preparing a statement that is clearly separate from the release of the NSO, but not for the purpose of modifying or delaying the release of the NSO] - UNECE Statistical Division Slide 10 Additional tabulation Requests from users, especially government users, for tabulation using census data but with definitions that deviate from those used in the official results, should be carried out by the NSO as statistical services An example may be indicators for allocation of funds or seats to regions and municipalities. These definitions may differ for good reasons from the international statistical standards used for the main results - UNECE Statistical Division Slide 11 Additional tabulation (ctd.) In the user consultation during the planning process of the census, the NSO has to get a full picture of at least government requests for such special tabulations The NSO has to make sure that such requests for additional tabulation can be easily met with the individual data from the census Avoid at all cost that definitions that are not in line with international standards are imposed from outside the statistical system to be used for the main results from the census - UNECE Statistical Division Slide 12 Summary Census laws should be rather detailed concerning processes, rights and obligations, but not so detailed on content Census laws should not deviate from the general provisions in the statistical law, but rather specify additional safeguards to ensure that the fundamental principles are respected in the context of the census where the risk of violation is greater compared to other activties of official statistics - UNECE Statistical Division Slide 13
