A project based at the University of Aberdeen and directed by Clive Lee systematically re-worked county-level occupation/industry data from all censuses 1841-1971 to the 1968 Standard Industrial Classification, distinguishing males and females. Lee calculated two alternative sets of data, Series A and Series B. The former is for Registration Counties and follows the nineteenth century censuses approach of grouping distributive workers with those involved in manufacturing the same items. Series B is for Administra...
tive Counties and is closely modeled on employment classifications used in the 1970s; in consequence, sector 23 ('Distributive Trades') is much larger. Lee's book provides a detailed discussion of the difference between the two series. Unfortunately, Lee did not list data for all individual counties: For Scotland, the original counties were aggregated to the regions of the 1975-96 period. For Wales, all counties were grouped into just 'Glamorgan and Monmouthshire' and 'North and West Wales'. He did provide data for all individual Registration Counties in England, but his data for Administrative Counties merges the parts of Lincolnshire, Suffolk and Sussex. Given that these are derived data and that our system holds many of the original occupational tables he used, we hold Lee's data only for actual counties and nations already in our system.
