The approach, or design, chosen for the 2011 Census drew on experiences from the 2001 Census, contemporary world best practice and changes in available technology. It also took account of the comments received from respondents to proposals published in a discussion paper in October 2003.
The design included the following major innovations:
multiple enumeration approaches, targeted at specific areas, including post-out of questionnaires, supported by an accurate and up-to-date address register
online completion of questionnaires
tracking of each form from printing to processing through a robust questionnaire tracking system
more functions for the call centre, acting as a hub for query resolution and the issuing of additional questionnaires
follow-up teams, targeted on poor response areas
use of technology in the field to monitor progress and direct the follow-up operation

For a more detailed description of the design, download the White Paper published in December 2008, which details the extensive consultation to identify requirements for census data, sets out the topics and questions proposed for inclusion, and highlights changes in methodology.
An information paper – a precursor to the White Paper - was published in March 2004. This paper highlights the statistical and operational strategic aims that helped to frame the design. It also outlines the major changes that were proposed from the 2001 approach, indicating the benefits and risks. Download the information paper The 2011 Census: A Design for England and Wales.
