| (P724)?Digest: | The primary, secondary and tertiary (PST) system for classifying occupations in economic sectors was first developed by Wrigley and Davies in 2004 as part of the project ‘The Occupational Structure of Britain ca. 1379–1911’ at the University of Cambridge. It followed an approach that had already been developed in broad terms by Colin Clark. PST was subsequently used in 174 projects and was offered in further versions in 2006, 2008 and 2010. The taxonomy categorises occupations according to a four-point system, which ultimately identifies the hierarchical levels of the vocabulary (sector, occupational group, occupational sub-group, occupation). In total, PST has eight sectors which, in addition to primary and secondary activities, primarily identify the tertiary professions and missing or unspecified professions. A definition table containing a total of 1,635 different occupational groups and the four-point code was published on the website in April 2010 and is available as an Excel file. A dictionary with 2,614 occupations and their PST codes is also available. The service is rounded off by a reference table with 31,999 different spellings of the coded occupations. Wrigley also wrote a documentation in which he addressed the methodological challenges posed by temporal and social changes. PST was intended to be particularly useful for international comparisons in order to reveal economic structures of different times and regions. |
