Standard Occupational Classification (SOC 2000) and NS-SEC on the Labour Force Survey

The March to May Labour Force Survey (LFS) dataset released on 18 July 2001 contained several new classifications for the first time.

This page deals with two of these; the Standard Occupational Classification (SOC) 2000 which replaced SOC 90 and the National Statistics Socio-economic Classification (NS-SEC) which is now used in place of Social Class (SC) and Socio-economic Group (SEG).

SOC 2000

SOC 2000 was introduced because SOC 90 became outdated.

The extensive revisions to the SOC included a tighter definition of managerial occupations and the movement of many job titles between major groups to reflect the repositioning of certain jobs.

New occupations have been introduced in the fields of computing, environment and conservation and customer service occupations.

Most of the major groups have been renamed and all have a different composition in terms of job titles compared with their SOC 90 counterparts.

From Spring 2001 the LFS classified people's occupations to SOC 2000.

Information about the key differences between this and the previous (SOC90) classification were published in the July 2001 issue of Labour Market Trends (1.89 Mb Pdf) .

The article was based on data from the LFS summer 2000 quarter that was dual-coded to both SOC 90 and SOC 2000 and on the LFS winter 1996/1997 quarter that was recoded to both classifications.

SOC 2000 is available on micro-datasets from LFS spring 2001 quarter and is also included in the Spring edition of the LFS quarterly supplement and the August edition of Labour Market Trends.

The Office for National Statistics (ONS) has produced a limited set of historic time series estimates on a SOC 2000 basis to meet users needs, these are considered the best available.

These estimates are based on the LFS winter 2000/01 dual-coded quarter, because there is no direct mapping between the two classifications.

The table below shows the LFS data for all in employment for Spring 2001 at the major group level of the classification.

NS-SEC

The NS-SEC is an occupationally based classification designed to categorise the whole adult population.

It is available from the Spring 2001 micro-datasets and the Summer 2001 LFS quarterly supplement. This concept relied on new questions introduced in the Spring quarter and as such, it is difficult to provide any historic data on a consistent basis.

The version of the classification, which is used for most analyses, has eight classes, the first of which can be subdivided.

The table below presents data from the LFS in these categories.
