This dataset provides 2011 Census estimates that classify the workplace population in England and Wales by passports held. The estimates are as at census day, 27 March 2011.

This information will provide a measure of the number of citizens from other countries living in the UK and provide international research to compare the origins and destinations of migrants. The statistics are used to identify whether the population eligible to vote actually registers to vote, and may be needed for any electoral reforms.

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.
