Stata code for mapping the Standard Occupational Classification 2000 (SOC2010) to the International Standard Classification of Occupations (ISCO08).
The Stata dofile below maps the occupation categories of the the UK Standard Occupational Classification 2010 to the International Standard Classification of Occupations 2008 using the guidelines available from the Office for National Statistics (ONS).
The mapping has three elements: 1:1 mapping of SOC2010 categories with equivalents in ISCO08, 1-to-2 mapping of SOC2010 categories corresponding to two ISCO08 categories, and indicating those ISCO08 categories with no SOC2010 equivalent.
The 1-to-2 mapping is done using a random 50:50 or 40:60 assignment to reflect the proportions suggested by ONS (see guidelines above). – Given the random assignment the proportions are occasionally not exact 50% or 40/60% and users of the code might want to re-run the respective lines to achieve closer proportions if necessary.
Do-File for Soc2010 to ISCO2008 conversion (using the UK Labour Force variable SOC10M): SOC10M_to_ISCO08_v1_1_20160409 (Do-file).
