This dataset provides 2011 Census estimates that classify usual residents in England and Wales by passports held and by age of arrival in the UK. The estimates are as at census day, 27 March 2011.

This dataset counts each person only once, therefore people only appear in one category even if they hold more than one passport.

In cases where a person recorded having more than one passport, they were categorised in the following priority order: 1. UK passport, 2. Irish passport, 3. Other passport

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.
