2010 World Census Programme

Endorsed by the United Nations Statistical Commission in March 2005 and adopted by the United Nations Economic and Social Council in July 2005

Three essential goals of Programme:

for Member States to carry out a population and housing census during the period 2005-2014 and to disseminate census results in a timely manner

to agree on a set of acceptable international principles and recommendations governing the conduct of a census

to facilitate countries in conducting censuses

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,

concerns raised against traditional censuses
Concerns raised against traditional censuses
  • Periodicity of data production
  • Prohibitive costs
  • Untimeliness of census results
  • Under-coverage
  • In some cases questionable data quality
  • Inflexibility

  • 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

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)

22–26 October 2007

principles and recommendations alternative approaches29
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

principles and recommendations alternative approaches30
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

22–26 October 2007

principles and recommendations alternative approaches31
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
