The 2007 Census Test: evaluation of key objectives.

The Office for National Statistics conducted a major census field test in May and June 2007 as part of the planning and preparation for the next census of population and housing in England and Wales in 2011. The 2007 Census Test was a large scale test covering approximately 100,000 household in five local authorities (LAs) selected to reflect a range of geographic conditions and social characteristics. Within England the Test covered parts of Bath and North East Somerset, Camden, Liverpool and Stoke on Trent. In Wales the Test took place in Carmarthenshire. The selected LAs were chosen to provide a varied cross section of the population and types of housing that would be covered in a full census. This article summarises the evaluation results and, where decided, decisions for 2011 on four key aspects of the Test: delivery method - post-out compared with hand delivery; inclusion of an income question; outsourcing recruitment, training and pay; and liaison with LAs.
