Where the distribution of staff across functional categories is not directly known it has in appropriate cases been estimated by proportional allocation e.g. proportions in earlier year’s data are applied to the current year's total or PES head office staff are distributed across functional categories in the same proportions as PES local office staff. Total staff in each functional category in principle include all management and support staff. Where data for part-time staff are available they are counted as a half of a full-time equivalent. Staff hired through a labour market programme which fully subsidises their wage are not included.
