This dataset provides 2011 estimates that classify usual residents in households in United Kingdom by NS-SeC of Household Reference Person. The estimates are as at census day, 27 March 2011.

The National Statistics Socio-economic Classification (NS-SeC) provides an indication of socio-economic position based on occupation. Similar estimates from the 2001 Census were provided in table UV33, however there may be some differences as these estimates were based on Standard Occupational Classification SOC2000. The rebased version of NS-SeC used in census results uses occupation coded to the SOC version released in June 2010 (SOC2010).

More information about the Standard Occupational Classification 2010 (SOC2010) can be found here: http://www.ons.gov.uk/ons/guide-method/classifications/current-standard-classifications/soc2010/index.html.

In Northern Ireland this table is numbered QS608NI.

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.
