The National Statistics Socio-economic Classification (UK)

From 2001, the National Statistics Socio-economic Classification (NS-SEC) has been used for official statistics and surveys. It was rebased in 2010.1 It replaces social class based on occupation and socio-economic groups. The information required to create the NS-SEC is occupation (coded to the Standard Occupational Classification 2000) and details of employment status (whether an employer, self-employed, or employee; whether a supervisor; number of employees at the workplace) (see Box A8.1). There are eight classes, the first of which can be subdivided.

A simpler, self-coded version of the NS-SEC has been developed with five classes for use in postal surveys or where detailed occupation information is not needed (Box A8.2).
