National Statistics Socio-economic classification (NS-SeC)

Mnemonic reference (code): NS-SeC

Type: Derived variable

Definition: The National Statistics Socio-economic Classification (NS-SeC) provides an indication of socio-economic position based on occupation. It is an Office for National Statistics standard classification.

To assign a person aged 16 and over to an NS-SeC category their occupation title is combined with information about their employment status, whether they are employed or self-employed and whether or not they supervise other employees. Full-time students are recorded in the ‘full-time students' category regardless of whether they are economically active or not.

Although all people aged 16 and over are assigned to a NS-SeC category, statistical outputs for this variable are generally based on the 16 to 74 years old population due to statistical disclosure control considerations

The rebased version of NS-SeC used in census results uses occupation coded to SOC2010.

Information about the classification is available here:

Since the 2011 Census did not ask a question about the number of employees at a person's workplace, the reduced method of deriving NS-SeC (which does not require this information) is used.

Known comparability issues:

The version of NS-SeC used in the 2011 Census results uses occupation titles coded to the SOC2010, whereas the 2001 Census used codes as defined by SOC2000. In 2011, because the census did not ask a question about the number of employees at a person’s workplace, a reduced method of deriving NS-SeC (which does not require this information) was used. In addition, in 2011, rules were used to estimate a category of NS-SeC for any person who did not have occupation details, however, in 2001, there was an extra category of ‘Not classified’, within which 19 per cent of the population fell. These factors mean direct comparisons between the 2001 and 2011 census results are not possible without further processing of the data.
