  8. Principles and Recommendations - major changes Orientation • Emphasis on production of outputs for evidence-based decision making • Recognition of an integrated statistical system for the production of outputs • Non-prescription of data sources for outputs Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  9. Outputs/tabulations • Basic/essential tabulations • Top priority • Providing minimum statistics for countries in difficult circumstances • Population (20) • Housing (7) • Recommended tabulations • Adequate for meeting essential data needs for evidence-based planning, monitoring and implementation of national policies • Population (33) • Housing (19) • Optimal tabulations • Meet the needs of most data users nationally and internationally Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  10. On the recommended tabulations • Reflect essential data needs - relevance at national and international levels • Potential for production of detailed statistics at lowest geographical level • Developed independently of source • Produced at least once in the period 2005-2014 Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  11. Set of recommended tabulations • Number of recommended by broad topic (51 tables) • Geographical and internal migration characteristics – 6 • International migration characteristics – 4 • Household and family characteristics – 3 • Demographic and social characteristics – 2 • Fertility and mortality - 4 • Educational characteristics - 3 • Economic characteristics – 8 • Disability characteristics – 3 • Housing characteristics - 19 • Produced at least once in the period 2005-2014 Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  14. Non-core to core Date of birth of the last child born alive Births in the past 12 months Household deaths in the past 12 months Deaths among children born in the past 12 months Country of birth Year or period of arrival Disability status Core to non-core Time worked Alternate core topics Place of previous residence Place of residence at a specified date in the past Changes in core topics - Population Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  15. New core Fuel used for cooking Main source of drinking water Information technology and communication devices in the household Core to non-core Year or period of construction Useful floor space Rental and owner-occupied housing costs Separate core topics – previously one Type of toilet Sewage disposal Changes in core topics – Housing Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  16. Principles and Recommendations - major changes • Introducing definition of Place of usual residence (a) The place at which the person has lived continuously for most of the last 12 months (that is, for at least six months and one day), not including temporary absences for holidays or work assignments, or intends to live for at least six months; OR (b) The place at which the person has lived continuously for at least the last 12 months, not including temporary absences for holidays or work assignments, or intends to live for at least 12 months. • Impact on regional and international data comparability Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  17. Principles and Recommendations - major changes New classification of living quarters that: • With clearer distinction between conventional and non-conventional housing units • Enlarges the taxonomy of collective living quarters Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  18. Living quarters Housing units Collective living quarters Conven. dwellings Hotels Basic dwellings Insti- tutions Temp. Hous. units Camps Mobile Hous. units Other Marginal Hous. units Impro- vised Not for habit.

  20. Principles and Recommendations - major changes Alternative approaches • Introducing elaboration of alternative approaches • Traditional census – most countries • Register based census • Rolling surveys (with national variants) • UNSD website – national examples of alternative approaches Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  21. Concerns raised against traditional censuses • Periodicity of data production • Prohibitive costs • Untimeliness of census results • Under-coverage • In some cases questionable data quality • Inflexibility Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  22. Principles and Recommendations – Alternative approaches Register based census - Prerequisites • Personal identification number • Comprehensive and functioning system of registers • Legal basis • Public trust • Unique and uniform coding systems • Record linking across registers Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  23. Principles and Recommendations – Alternative approaches Register based census - Advantages • Timeliness of data • Reduced cost associated with data compilation • Reduced respondent burden • Maximizes use of data collected by different agencies • Flexibility in terms of reference date and periodicity Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  24. Principles and Recommendations – Alternative approaches Register based census - Disadvantages • Lack of flexibility – expanding data items • Completeness of data limited to data available in registers • High initial investment setting up registers • Need continuous financial and other resources to sustain registers • Harmonization of concepts and definitions across register could be an issue Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  27. Principles and Recommendations – Alternative approaches Rolling surveys - Disadvantages • Technically demanding • Multi-year planning and testing necessary • Possibility of double-reporting Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  28. Principles and Recommendations – Alternative approaches National examples of variants of rolling surveys • USA approach based on a combination of • Traditional 10-year census using the short form, and • American Community Survey (continuous cumulative survey) • French rolling census (continuous cumulative survey) Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  29. Principles and Recommendations – Alternative approaches USA approach - Traditional censuses with yearly updates • Census year: Total population count and basic characteristics based on short questionnaire • Every year: Large household survey that replaces decennial long form • Data from survey used to model estimates Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  30. Principles and Recommendations – Alternative approaches USA approach - Traditional censuses with yearly updates Some issues • Requires building and keeping the address frame up-to-date • Some operational risks likely reduced – short questionnaire only • Work in progress – lessons learnt on the go Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  31. Principles and Recommendations – Alternative approaches French approach - rolling census • Data collected each year used for modeling of estimates • Quinquennial rolling cycle: Every year, Y, data are produced on the basis of data collected in Y-4, Y-3, Y-2, Y-1 and Y with the average on Y-2 • For communes less than 10,000 – full count once in a five year period • For communes over 10,000 – sample of 8% of dwellings each year for five years Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007

  32. Principles and Recommendations – Alternative approaches French approach - rolling census Some issues • Inventory of buildings – continuously updated building register • Close relationship between statistical office and communes • Work in progress – lessons learnt on the go Workshop on Census Cartography and Management, Port-of-Spain, Trinidad and Tobago, 22–26 October 2007
