  1. Experiences of the 2010 Round of Population and Housing Censuses: A global OverviewMargaret MbogoniUnited Nations Statistics Division

  2. Summary Implementation of 2010 census round Country experiences Census methodology Enumeration methods Use of technology Methods of data dissemination Collaboration among countries Successes/achievements Challengesexperienced

  3. Surveys on country experience during 2010 round Mid-2011 and early 2012 UNSD and USCB conducted survey on country practices for 2010 censuses Objectives of the survey Document early lessons learned from the 2010 round Identify preliminary recommendations for the Statistical Commission to consider as planning begins on the 2020 World Programme on Population and Housing Censuses 2009-2010 UNSD survey

  4. Response to 2011/2012 survey by region 126 countries or areas responded to survey

  5. Salient findings More countries undertaking a census in 2010 round than in 2000 round 26 did not conduct a census for 2000 round Only 7 countries with no information on plans for 2010 round 25 countries rescheduled their censuses for 2010 round (20%) Initially, 2010 was peak year for census taking for 2010 round Due to postponements, 2011 became peak for the round Reasons for postponement include: Budgetary constraints Technical issues Lack of skilled staff Political situations

  6. Salient findings (contd.) As of 1 November 2012 192 countries already conducted census Population enumerated = 6.1 billion representing 89% of world population Countries already conducted census Population enumerated

  7. Salient findings (contd.) • Changes in how countries conduct censuses • Increase in use of alternative methodologies from 2000 round • Use of multiple sources to generate census data • Multi-mode enumeration methods • Increased use of improved technology in all phases of census • Implementation of new technologies most cited successful aspect of census • Reasons for changes: • Reduce cost of census • Improve quality of data • Improve timeliness of dissemination of census results

  8. Main methodology for census In 2010 census round: Full field enumeration still dominant methodology for population and housing censuses (85%) Use of alternative methodologies 10% use administrative registers 5% use other methods mainly combinations Application of alternative methods not uniform across countries and needs careful documentation and study

  9. Main census Methodology by region

  10. Use of other sources of data

  11. Use of multi-sources of data

  12. Use of alternative methodologies

  13. Enumeration methods

  14. Use of technology - Cartography Census cartography one of census domains that have benefited the most from technological innovations In 2010 census round: 58% use digitized maps 74% use GPS/GIS 25% aerial photography 24% satellite imagery Source: UNSD survey conducted in 2009-2010

  15. Use of technology (contd.) • Predicted cost or time savings by using new technology • Yes: 79 – 76% • No: 25 – 24% • Realized cost or time savings by using new technology • Yes: 70 – 74% • No: 25 -26%

  16. Use of technology (contd.) • Benefits of using new technology • Time savings - 62% • Improved data quality - 57% • Improved coverage - 37% • Cost savings - 36% • Increased participation/response rates – 23% • Risks of using new technology • Increased cost – 29% • Obstacles faced in use of new technology • Staff resources/expertise – 52% • Financial resources – 37%

  17. Contracting out use of technology • Yes: 49% • No: 51% • Successes about contracting out use of technology • Contract management ~ 23 – 18% • Staying within scope ~28 - 22% • Adhering to budget ~29 – 23% • Adhering to schedule ~30 - 24% • Improved census integration ~25 - 20% • Other ~5 – 4% • Challenges of contracting out use of technology • Contract management ~ 16 - 13% • Adhering to schedule ~ 14 - 11% • Adhering to budget ~ 13 - 10%

  18. Contracting out use of technology (contd.) More in-depth analysis of results on previous slide is needed to show successes and challenges by census methodology

  19. Data dissemination – primary method Primary method of data dissemination Paper publications ~ 66 - 52% Static web pages (html, pdf, Excel) ~ 34 – 28% Interactive online databases ~ 17 - 14% Africa Paper publications – 88% Static web pages – 8% America North Static web pages - 44% Paper publications – 31% CD-Rom/DVD – 19%

  20. Data dissemination – primary method America South Interactive online databases – 43% Static web pages (29%) Paper publications, CD-Rom/DVD – 14% Asia Paper publications – 73% Static web pages – 23% Europe Static web pages – 39% Interactive online databases – 36% Paper publications - 22% Oceania Paper publications - 67% Static web pages - 33%

  21. Collaboration among countries Areas in which collaborated with other countries Total Data dissemination - 27% Questionnaire design – 21% Alternative methodologies - 21% New technologies – 18% Africa Post enumeration survey (PES) – 30% Cartography - 26% Data dissemination – 22% Data analysis - 22%

  22. Collaboration among countries (contd.) Areas in which collaborated with other countries America North Data capture – 39% Questionnaire design – 33% Data processing – 33% America South Cartography, data processing, data analysis - 29% Asia Data dissemination - 26% New technologies, questionnaire design, data capture – 23%

  23. Collaboration among countries (contd.) Areas in which collaborated with other countries Europe Data dissemination – 31% Alternative methodologies – 28% New technologies – 11% Oceania Alternative meth., questionnaire design, data collection – 57% Cartography, data processing, data dissemination – 43% New technologies, data capture, data analysis – 29%

  24. Successes in 2010 round Implemented new technologies ~ 70 - 56% Met deadlines ~ 62 - 49% Kept within a budget ~ 59 - 47% Improved/maintained data quality ~ 58 - 46% Improved logistics and coordination ~ 56 - 44% Improved data dissemination ~ 50 - 40% Improved/maintained response/participation rates ~ 47 - 37% Implemented new methodologies ~ 46 – 37% Other ~ 21 - 17%

  25. Challenges during 2010 round Cost ~ 88 - 70% Timeliness ~ 56 - 44% Data quality ~ 43 - 42% Public perception ~ 46 - 37% Response rates ~ 45 - 36% Privacy ~ 37 - 29%

  26. Challenges for the 2010 round In spite of achievements during 2010 round, still challenges: Use of new technology (scanning, GIS, PDA) Financing for the census Lack of adequate skilled personnel Institution of annonymization procedures for dissemination of micro-data Census evaluation (both operation and data) Public concerns over privacy issues Enhancing statistical literacy of basic data users Implementing alternative approaches to traditional census Political situations
