This release provides 2011 Census estimates for postcodes in England and Wales. These summary figures give estimates of the number of usual residents, by sex, and the number of households with at least one usual resident, for each unit postcode at as census day, 27 March 2011.

As the purpose of this product is to provide counts of usual residents by postcode, postcodes which do not contain usual residents are omitted.

The CD-ROM has data files in csv format containing:

• for each postcode, estimates of the number of usual residents (total, males, females) and the number of households with at least one usual resident
• for each split postcode, the corresponding Output Area, the total number of usual residents in the postcode, and an indicator of the percentage of each postcode that is in the corresponding Output Area.

To protect the confidentiality of individuals information these summary figures provide the most level of detail from the census for unit postcodes. They may be used in combination with other published statistics for Output Areas should users wish to perform their own analysis at postcode level.
