Information on the previous occupations of asylum applicants is not centrally recorded and is held in an individual’s paper case file or within the notes section of the case information database (CID). Such data are not aggregated in national reporting systems, which would mean this question could be answered only through a disproportionately expensive manual case search to collate the data.
The Home Office publishes immigration statistics annually and quarterly, which are available from the Home Office research and statistics website.
This includes information on asylum applications by nationality. The latest statistics can be found in asylum volume 1, data table as_01 at the following link : https://www.gov.uk/government/statistics/immigration-statistics-april-to-june-2015-data-tables
