This dataset provides 2011 Census estimates of the usual resident population of the UK who were living outside the UK one year before the Census. The data classifies people currently resident in each local authority or higher area in the UK by the country in which they were resident one year before the Census. The country classification used is an expanded classification providing more detail in the breakdown of the countries of origin. The estimates are as at census day, 27 March 2011.

In order to protect against disclosure of personal information from the 2011 Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.

More details on the ONS Census disclosure control strategy may be found on the Statistical Disclosure Control page on the ONS web site.
