The population census is one of the major statistical collections that countries undertake.

 A small number of countries have started using electronic data collection in their most recent rounds of population censuses.

  The following documents relate to this subject:

The Australian 2006 Census and the Internet

Prepared by Paul Williams, Australian Bureau of Statistics, for the
UNECE/Eurostat Work Session on Electronic Raw Data Reporting ( Geneva, 6-8 November 2006).

  Executive Summary

 The role of the Australian Census of Population and Housing is to accurately measure the characteristics of all people in Australian territories on census night. The census aims to provide high quality data for small geographic areas and for small population groups.

  This paper briefly outlines the processes that were put in place to provide an Internet option to the Australian public at the 2006 Census and the experience with the solution. The use of the Internet provided new opportunities to reach out to geographic areas and population groups that were difficult to enumerate using traditional census methodology. As well there are a range of risks that needed to be managed to ensure that the implementation of the Internet solution was both operationally sound and secure and the quality of the census was maintained.

Census Data Collecting by Internet. Spanish Experience In 2001

Prepared by Adolfo Galvez Moraleda, INE, Spain, for the
UNECE/Eurostat Work Session on Electronic Raw Data Reporting ( Geneva, 6-8 November 2006).

  Executive Summary

  Spain has conducted census operations regularly from the second half of the 18th century. During the last century, censuses of dwellings and population have been undertaken once a decade.

  In 2001, the National Statistical Institute of Spain (INE) relied on a strong technological component throughout the entire census process. Main issues to be pointed out in this field are:

  1. Questionnaires were “pre-filled” with personal data from the Population Register. They were carefully designed to allow digitalisation into a high performance system, which enabled most of the information to be processed within three months after collection.
  2. The option to complete questionnaires on the Internet was made available for the whole population.
  3. The dissemination system is based in datawarehouse technology. This includes OLAP navigation techniques that allow users to design tables according to their needs and analyse the information presented requiring more details and at the same time guaranteeing statistical confidentiality.

Census was based on Spanish Population Register (Padrón). Padrón is established in each municipality to record individual residence information. This information is limited to only a few characteristics: name, sex, date and place of birth, citizenship and educational attainment. In 2001 Census the questionnaires were “pre-printed” with the Padrón data to be confirmed or updated by respondents. More than 30.000 interviewers worked on data collecting, firstly distributing paper forms and after a short time picking up them from the dwellings .
