This release provides population estimates, of the usually resident population, by five-year age bands and sex, as well as household estimates for all local authorities (or equivalent) in the constituent countries of the United Kingdom. This will combine data for Scotland with data already published for England, Wales, and Northern Ireland.
This release provides population estimates of the usually resident population by age and sex, and households estimates, for each local authority in the United Kingdom. The release draws together results from each of the three censuses in England and Wales, Scotland, and in Northern Ireland, that were held on 27 March 2011.
This release supplements the first release of UK 2011 Census data in the 'Population and household estimates for the United Kingdom' published 17 December 2012.
The statistical bulletin accompanying this release also adds to the analysis included in the 17 December release, providing analysis of the new household estimates, new commentary on population density, and further analysis of the population estimates made possible because of the reduced level of rounding applied to the figures in this release.
Due to the breadth and depth of census data, results from the 2011 Census are being released in stages. Subsequent releases of UK census data will be available as soon as all constituent country data are available. An outline of the timetable for subsequent UK releases has been published in the 2011 Census prospectus (415.9 Kb Pdf) .
Further information about the methodology and quality assurance processes for the 2011 Censuses in England and Wales, Scotland and Northern Ireland are available from their respective websites.
