You asked
Could you please provide a breakdown of the UK population by postcode area? That is, the population in each post code area throughout the UK.
We said
Thank you for your email requesting data pertaining to a breakdown of the UK population by postcode area.
The Office for National Statistics has not published data at postcode level for the United Kingdom.
England and Wales
The information you have requested is available for England and Wales, and is published as Table KS101EW, available to download from the Nomis website. The population estimates are based on data from the 2011 Census and refer to the usual resident population on census day, 27th March 2011. A usual resident is anyone, who on census day, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more, or had a permanent UK address and was outside the UK and intended to be outside the UK for less than 12 months. Please note steps have been taken by the Office for National Statistics to protect the confidentiality of personal information.

If you have any further questions may I suggest that, rather than using the Freedom of Information route, you contact Census Customer Services directly. They will be glad to deal with any census related queries and the process is much speedier.
