The information requested is not held centrally and could be provided only at disproportionate cost. Information on full-time and part-time employee jobs in English local authorities is held by the Employers Organisation and data on the population in each English authority are available from the 2001 census. Using these data the Office of the Deputy Prime Minister has calculated the proportion of local authority employees to total population in the categories of local authority requested. A table showing these data is available in the Library of the House. It should be noted that the population figures refer to the total population of each authority rather than just the adult population.
