This article describes the revision of the Standard Occupational Classification from its 2000 to its 2010 version (SOC2010).
It details the revision process, outlines the major areas of change and illustrates the impact of these changes on national estimates of employment by occupation. Given that the revision of a classification introduces potential discontinuities in the interpretation of occupational information over time, the final section discusses ways in which such discontinuities can be minimised.
