Estimated number of workers in each 2011 Census output area in England and Wales, processed and saved in an easy to analyse format. Original Source: https://www.nomisweb.co.uk/datasets/1300_1 This dataset provides 2011 Census estimates of the workplace population in England and Wales by residence type (household or communal resident), by sex and by age. The estimates are as at census day, 27 March 2011. Statistics about the number and demographic characteristics of people are used to monitor differences and track how these proportions change over time. Statistical Disclosure Control 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 http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site.
