Nationality estimates (2004-2015) tool

**Updated 21/11/16 to include 2015 data

In July 2015, the Office for National Statistics (ONS) released a set of re-weighted population estimates by country of birth and nationality for calendar years 2004 to 2013 by local authority. These are the result of the Annual Population Survey (APS) being re-weighted in line with the results of the 2011 Census in March 2015. These were followed in August 2015 by the release of population estimates by country of birth and nationality for calendar year 2014 by local authority. The data released by ONS has been provided rounded to the nearest thousand with estimates for the City of London combined with those for Westminster.

Estimates have been rounded to the nearest thousand and care should be taken in interpreting small numbers. Some data in the visualisation shows up as a blank value. This is because Tableau is unable to interpret the following symbols released by ONS:

. No contact This value is used where the APS has had no contact with any resident with a particular country of birth or nationality.
: Not available This value is used where estimates for a geographical area are not available in the source data.
c Not available due to disclosure control This value is used where an estimate cannot be disclosed due to confidentiality reasons, as there have been less than 3 APS contacts.
0~ Rounded to zero This value is used where an estimate or a confidence interval rounds to zero. All estimates and confidence intervals in these tables are rounded to the nearest thousand, so 0~ indicates that the unrounded value is less than 500.

The visualisation also does not take into account the confidence levels applied by ONS. These can be seen in the associated Excel file that is available to download.

Use of the visualisation: The visualisation lets you select a pre-defined country grouping or an individual country or selection of countries. To clear the selected countries, choosing (All) for each grouping will re-set.

Further information on the confidence levels and data can be found on the ONS website.

An Update and visualisation of country of birth estimates are also available on the Population by Nationality page.

A list of countries which fall under each country group can also be found in Appendix A of the Update.
