A number of measures have been produced to help users understand the quality of the 2001 Census for each local authority. These have been presented on the National Statistics website as they have become available.
This information has been brought together for each local authority in England and Wales. Each local authority page contains links to a profile, population pyramid, One Number Census quality assurance pack, quality indicators, One Number Census person and household imputation rates, question non-response rates and 95 per cent confidence intervals for the population estimates.
