ECE Work Session on Population Censuses Geneva, 23-25 November 2004 Types of censuses, enumeration methods and selected operational aspects: results of the ECE questionnaire Paolo Valente Social and Demographic Statistics Section UN Economic Commission for Europe - Statistical Division
Summary of presentation Review of census methods used in 2000 round, also in relation with legal and administrative context.“Bonus slides” with preliminary general results on some topics not covered in the paper: - Statistical uses of census data - Publicity and information campaign - Census evaluation - Census costsby main budget lines - Main problems faced by countries in the 2000 roundConclusions
The 2000 round of population and housing censuses in the ECE region Censuses taken in 48 out of 55 countries in the ECE regionIn all countries the census was taken between 1999 and 2002, with a few exceptions: - Turkmenistan, Israel and Malta: 1995 - Republic of Moldova: October 2004 Replies to the ECE questionnaire on censuses available for 44 countries (43 out of the 48 ECE countries where census was taken + Australia)
Legal context for the 2000 censuses: Existence of statistical legislation Census act existing in 38 countries (86%)Statistics act existing in 36 countries (82%)Data protection act existing in 33 countries (75%) No significant differences among different groups of countries, but……in countries using registers, possible association with existence of Statistics acts and Data protection acts, rather then Census acts?
Administrative context:Existence of use of PIN (2/2) PIN is not necessary to use registers for censuses (examples: Netherlands, Spain, Switzerland) Countries using registers for censuses and where PIN exist, use it extensively for statistical purposes Other countries make limited use of PIN for censuses and statistical surveys (because of restrictions?)
Administrative context:Existence of registers No population register No register-based census!
Administrative context:… and use of censuses for registers Confidentiality implications!
Publicity campaign (1/2) Publicity campaign carried out in 41 countries No publicity campaign in Belgium, Denmark and the Netherlands……but publicity campaign in some countries with register-based censuses (Finland and Norway)
Publicity campaign: “Innovative approaches…” • In Canada, no national TV, but: - free ads/inserts - sugar bags - milk cartoon - rail cars - calendar and agenda companies - mail inserts - plastic bags - ATMs, etc. • And in Italy: SMS!!!
Main problems and difficulties faced in the 2000 round of censuses
Conclusions In 2000 round, limited variability in census methodology adopted: most countries took traditional censusDifferent methods have different implications on various phases of censusIn 2010, much higher variability is expected with regard to census methods (seminar, pres. on Plans for 2010)
Implications for 2010 recommendations (1/2) New expanded section on census methodology (2000 recommendations focussed on content)Objective: not to “recommend” specific approaches, but rather to “inform” about possible options and help countries to evaluate themReview of different approaches, discussing: - necessary conditions - implications on various phases of census - advantages and disadvantages
Implications for 2010 recommendations (2/2) Possible areas to be covered: - Possible uses of registers - Possible uses of sample surveys - Other approaches (“rolling census”?) - Census evaluation (coverage and quality) - Publicity and information campaign - …
