SIC80 Activity (4-digit) to SIC92 Division (2-digit) one-to-one mapping based on job stayers between Autumn 1993 and Winter 1993/4, implementing a recode in a STATA do-file (REVISED 13 October 2016 to include previously omitted SIC codes when using recode based on ONS codes).

Autumn 1993 data give SIC 1980 Activities and Winter 1993/94 data give SIC 1992 Divisions and SIC 1992 Sections.

The second method is based on individuals remaining in the same job (stayers) between Autumn 1993 and Winter 1993/94.

Excel spreadsheet containing SIC80-SIC92 overlap-based correspondences and giving information about the overlap-based one-to-one mapping.SIC80 Activity (4-digit) to SIC92 Section (1-digit) one-to-one mapping based on overlapping data provided in the Seasonal Quarterly LFS dataset Autumn (September-November) 1993, implementing a recode in a STATA do-file.The first method is based on overlapping information provided in the LFS Autumn 1993 dataset on SIC80 Activity and SIC 1992 Section. Using two alternative methods, I have created direct mappings between SIC 1980 and SIC 1992. Jennifer Smith's one-to-one mapping between SIC 1980 and SIC 1992 ONS document prepared for the LFS Steering Group in October 2010 on the effect of the change to SIC 2007, including information about the mapping method used in the LFS.Ģ.SIC92 Class (4-digit) to SIC07 Section (1-digit) one-to-one mapping, implementing a recode in a STATA do-file.SIC92 Class (4-digit) to SIC07 Division (2-digit) one-to-one mapping, implementing a recode in a STATA do-file.Sean Milburn of the LFS Research team at the ONS Social Survey Divison has very kindly made available his coding to map SIC 1992 Classes to SIC 2007 Divisions or Sections. The reverse SIC92-SIC07 would be useful for time series analysis if SIC 2007 classification is wanted throughout.

The QLFS data from 2009 Q1 use a SIC07-SIC92 mapping from SIC 2007 Classes (4-digit level) to SIC 1992 Divisions, Sections and Sectors (2- and 1-digit levels). It is this direct mapping that is used to generate the ongoing industry information based on SIC 1992 after the changeover to SIC 2007 in 2009 Q1. The ONS LFS team therefore devised a modified direct, one-to-one, mapping.

The ONS realised that a proportional mapping based on the IDBR weighted correspondence between SIC 1992 (2003) and SIC 2007 (discussed here) would not be suitable for many purposes using LFS data, where those purposes required a mapping at individual level that was consistent over time. Office for National Statistics (ONS) one-to-one mapping between SIC 1992/SIC 2003 and SIC 2007 Further discussion can be found on my LFS SIC Mapping page. Before using resources for one-to-one mapping, please ensure that you are certain that a one-to-one mapping is most suitable for your purposes.
