The Great Britain Historical Database has been assembled as part of the ongoing Great Britain Historical GIS Project. The project aims to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain at sub-county scales. Further information about the project is available on A Vision of Britain webpages, where users can browse the database's documentation system online. The Great Britain Historical GIS Project has also produced digitised boundary data, which can be obtained from the UK Data Service Census Support service. Further information is available at census.ukdataservice.ac.uk There are two tables in this part of the Great Britain Historical Database : Wages holds wage statistics gathered by the Board of Trade Labour Department for 24 occupations in 87 towns from 1845 to 1906. Not all towns appear for all occupations. Minedays holds monthly data on hours worked in coal-mining for between 17 and 20 coalfields from January 1900 to December 1913. Please note: this study does not include information on named individuals and would therefore not be useful for personal family history research.
