The evaluation from the 2009 Census rehearsal has been published by ONS. The rehearsal was undertaken on 11 October 2009 and selected around 134,000 households in Newham, Lancaster and Anglesey.
- no significant problems found with any of the systems; questionnaire post out/back and tracking was successful
- response rate was lower than expected at 41 per cent; most common reason for non-response was the voluntary nature of the exercise
- internet returns were lower than expected at 8 per cent
- follow-up resource in 2011 will be increased, particularly in hard to count areas
