This release contains three tables on migration within Wales, cross-tabulated by ability to speak Welsh and one or more other topics from the census. Two tables are provided at both 2011 Census Merged Wards and Middle Layer Super Output Areas (MSOAs) level, and one table at Unitary Authority level. Each table is available to download as a reference table in Excel format.
The level of detail included in Detailed Characteristics tables means that, in order to prevent disclosure of individuals’ information, these tables are only produced for areas that have minimum population thresholds of 1,000 persons or 400 households. Some wards fall below this threshold. In these cases the ward is merged with a neighbouring ward, or wards, until the combined Census estimate for the merged wards is above both the minimum person (1,000) and household (400) threshold. Detailed characteristics are therefore produced for wards known as 2011 Census Merged Wards. The complete set of 2011 Census Merged Wards includes both those that have been merged, as well as those wards above the threshold that do not need to be merged. This gives complete coverage of England and Wales.
More information about MSOAs and 2011 Census Merged Wards is available from ONS Geography.
ONS will publish additional migration statistics for the whole of the UK later in 2014.
Cross-tabulations of other topics from the census are available for 2011 Census Merged Wards and Middle Layer Super Output Areas (MSOAs) in Detailed Characteristics tables, and for Output Areas in Local Characteristics tables. All Detailed and Local Characteristics are available on the Nomis website.
Further information about the census estimates, including details about the methodology used and information about how other population sub-groups are counted and defined, is available in the in the 2011 Census user guide.
Further information on the fitness for purpose of the statistics in this release can be found in the Quality and Methodology Information (157.6 Kb Pdf) paper.
These National Statistics are produced to high professional standards and released according to the arrangements approved by the UK Statistics Authority.
