2011 Census Roadshows and Statistical Disclosure Control Strategy.

The article provides updates of the 2011 Census roadshows and the Statistical Disclosure Control (SDC) strategy in Great Britain. It emphasizes that the Office for National Statistics (ONS) will establish a series of roadshow meetings in which it will report the selection of questions in the pre-census rehearsal, setting up of a Census Output User Council, and other census outputs including geography, coverage assessment, and quality assurance. The SDC strategy for 2011 offers three stages that review information resources and quantitatively evaluates the shortlist of methods which include record swapping, over-imputation, and the Australian Bureau of Statistics (ABS) cell perturbation to avoid disclosure risks and utility loss.
